However, this device uses the magnetic field emitted from the magnet to cause the movable part to float, which does not allow the movable part to move sufficiently.

[0015] like Figures 1 to 4 As shown, the thrust generating mechanism (thrust generating device) 1 according to the first embodiment includes: a moving portion 3 which can be moved on a plane G (reference Figure 3 and Figure 4 ) and is equipped with a plate-shaped first magnet (first magnet) 9; a linear first magnet (one side magnet portion) 5 and a second magnet (the other side magnet portion) 7, which are placed on a plane G and are located on both sides of the moving portion 3. It should be noted that although there is only one moving portion 3 in this embodiment, Figure 2 In order to show that the moving part 3 moves from the rear side to the front side (from Figure 2 The diagram shows a state where the moving parts 3 on the left and right sides are shown.

[0016] The moving part 3 has a plate-shaped first magnet 9 (refer to Figure 2 ), a non-magnetic housing 11 made of resin or the like covering the periphery of the plate-shaped first magnet 9 (reference Figure 1 ), and four wheels 13 (reference Figure 4 (a)), and formed in the front direction shown by arrow A ( Figure 1 、 Figure 2 as well as Figure 4 In addition, Figure 2 In the figure, for the sake of convenience, the illustration of the housing 11 and the wheel 13 in the moving part 3 is omitted (in other words, only the plate-shaped first magnet 9 is shown). Figure 3 and Figure 4 , the housing 11 in the moving portion 3 is omitted from the illustration (in other words, only the plate-shaped first magnet 9 and the wheel 13 are shown).

[0017] like Figure 2 As shown in (a), in each plate-shaped second magnet 9, the left side surface 15a on the lower side has an S-pole magnetic pole, and the right side surface (the other side surface) 9b on the upper side has an N-pole magnetic pole identical to the left side surface (one side surface) 9a of the plate-shaped first magnet 9. When the moving part 3 is placed on the plane G, the left side surface 9a and the right side surface 9b of the plate-shaped first magnet 9 are respectively perpendicular to the plane G (refer to FIG. Figure 3 ).

[0018] In addition, if Figure 4 As shown in FIG. 2( b ), in a state where the moving portion 3 is placed on the plane G, the moving portion 3 is moved perpendicularly to the front direction indicated by the arrow A and the height direction of the plate-shaped first magnet 9 ( Figure 4 (b) the up and down direction) Figure 4 A first center line (moving side center line) C1 passing through the center in the height direction of the plate-shaped first magnet 9 is parallel to the plane G when viewed in the direction passing through the paper in (b), hereinafter referred to as the “vertical direction”.

[0019] Here, about Figures 2 to 4 The plate-shaped first magnet 9 shown in the figure has a white portion as the N pole and a black portion as the S pole. Figure 6 It should be noted that, in this embodiment, the white portion is used as the N pole and the black portion is used as the S pole, but of course, the white portion can also be the S pole and the black portion can also be the N pole.

[0020] The moving direction of the moving unit 3 in this embodiment is restricted by each wheel 13 to either the forward direction (first direction) indicated by arrow A or the rearward direction opposite to the first direction. In other words, the housing 11 and the four front, rear, left, and right wheels 13 constitute a moving direction restriction unit that restricts the moving direction of the moving unit 3 to the front-rear direction.

[0021] like Figure 2As shown in (c), the linear first magnet portion 5 is composed of a plurality of plate-shaped second magnets (second magnets) 15 as plate-shaped permanent magnets arranged in the front-to-back direction, and the plurality of plate-shaped second magnets 15 are formed into the same shape as each other. Specifically, the linear first magnet portion 5 is constructed as follows: among the plate-shaped second magnets 15 adjacent to each other in the front and back, the lower half of the front of the plate-shaped second magnet 15 on the rear side is fixed to the upper half of the rear of the plate-shaped second magnet 15 on the front side in sequence by bonding or welding, thereby connecting each other, and then a non-magnetic shell not shown is used to cover the periphery of the plate-shaped second magnet 15. It should be noted that in Figure 2 In (c), for convenience of explanation, all the plate-shaped second magnets 15 constituting the linear first magnet portion 5 are partially shown in fragmentary form.

[0022] observe Figure 2 (a) Each of the plate-shaped second magnets 15 has an S-pole on the left side 15a at the bottom and an N-pole on the right side (the other side) 15b at the top. That is, Figure 3 As shown, the right side surface (opposing surface on one side) 15b of each plate-shaped second magnet 15 is able to face the left side surface (surface on one side) 9a of the plate-shaped first magnet 9 of the movable portion 3 that moves forward between the linear first magnet portion 5 and the linear second magnet portion 7, and the polarity is the same as that of the left side surface 9a. Therefore, a repulsive force CL is generated between the left side surface 9a of the plate-shaped first magnet 9 and the right side surface 15b of the plate-shaped second magnet 15. In addition, when the linear first magnet portion 5 is placed on the plane G, the left side surface 15a and the right side surface 15b of each plate-shaped second magnet 15 are each perpendicular to the plane G.

[0023] like Figure 4 As shown in (b) and (c), the lower end of the rear end portion of each plate-shaped second magnet 15 (for example, at Figure 4 (b) and (c) the lower right corner) contacts the plane G, and the lower end of the front end of each plate-shaped second magnet 15 (at Figure 4 (b) and (c) are the lower left corners) in a state of floating from plane G. In other words, the front end of each plate-shaped second magnet 15 is tilted upward so that the inclination angle between the bottom surface of the plate-shaped second magnet 15 and plane G becomes a predetermined angle (acute angle). In addition, the inclination angles of each plate-shaped second magnet 15 are the same as each other. Therefore, when the linear first magnet portion 5 is placed on plane G, when viewed from the vertical direction, the second center line (fixed side first center line) C2 passing through the center in the height direction of each plate-shaped second magnet 15 intersects with the first center line C1 of the plate-shaped first magnet 9 at a predetermined angle.

[0024] like Figure 2As shown in (b), the linear second magnet portion 7 is the same as the above-mentioned linear first magnet portion 5, and is composed of a plurality of plate-shaped third magnets 17 as plate-shaped permanent magnets arranged in the front and back, and the plurality of plate-shaped third magnets 17 are formed into the same shape as each other. Specifically, the linear second magnet portion 7 is constructed as follows: among the plate-shaped third magnets 17 adjacent to each other in the front and back, the front lower half of the plate-shaped third magnet 17 on the rear side is fixed to the rear upper half of the plate-shaped third magnet 17 on the front side in sequence by bonding or welding, thereby connecting each other, and then a non-magnetic shell not shown is used to cover the periphery of the third magnet 17. It should be noted that in Figure 2 (b) and Figure 2 (c) Similarly, for convenience of explanation, a portion of all the plate-shaped third magnets 17 constituting the linear second magnet portion 7 is shown.

[0025] observe Figure 2 (a) Each plate-shaped third magnet 17 has a lower left side (opposite side) 17a having the same S pole as the right side (other side) 9b of the plate-shaped first magnet 9, and an upper right side 17b having an N pole. Figure 3 As shown, the left side (opposing side) 17a of each planar third magnet 17 is able to face the right side (opposite side) 9b of the planar first magnet 9 of the movable portion 3, which moves forward between the linear first magnet portion 5 and the linear second magnet portion 7, and has the same polarity as that of the right side 9b. Therefore, a repulsive force CR is generated between the right side 9b of the planar first magnet 9 and the left side 17a of the planar third magnet 17. Furthermore, when the linear second magnet portion 7 is placed on the plane G, the left side 17a and right side 17b of each planar third magnet 17 are perpendicular to the plane G.

[0026] like Figure 4 As shown in (b) and (c), the lower end of the rear end portion of each plate-shaped third magnet 17 (for example, at Figure 4 (b) and (c) the lower right corner) contacts the plane G, and the front end of each plate-shaped third magnet 17 (at Figure 4(b) and (c) (the left end) are in a state of floating from plane G. In other words, the front end of each plate-shaped third magnet 17 is tilted upward so that the inclination angle formed by the bottom surface of the plate-shaped third magnet 17 and plane G is the same as the inclination angle formed by the bottom surface of the plate-shaped second magnet 15 and plane G, and the inclination angles of each plate-shaped third magnet 17 are the same. Therefore, when the linear second magnet portion 7 is placed on plane G, when viewed vertically, the third center line (the second center line on the fixed side) C3 passing through the height center of each plate-shaped third magnet 17 is parallel to the second center line C2 and intersects with the first center line C1 of the plate-shaped first magnet 9 at a predetermined angle (acute angle).

[0027] like Figure 1 As shown, the linear first magnet portion 5 and the linear second magnet portion 7 are formed to have the same length as each other. The linear first magnet portion 5 and the linear second magnet portion 7 are configured to be parallel to each other and face each other on the plane G at a predetermined interval. In this state, the linear first magnet portion 5 and the linear second magnet portion 7 are configured to be positioned further forward than the front end of the linear first magnet portion 5 when viewed from the vertical direction, and the forward displacement is half of the length of the plate-shaped third magnet 17 tilted at a predetermined angle in the front-to-back direction. That is, when viewing the linear first magnet portion 5 and the linear second magnet portion 7 from the vertical direction, each of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 is offset from each other front to back, and the offset is half of the front-to-back length of the magnet (reference Figure 1 ).

[0028] Specifically, in Figure 1 In the embodiment, the frontmost plate-shaped second magnet 15 ( Figure 1 The plate-shaped second magnet 15 located on the leftmost side of the second magnet portion 7 and the plate-shaped third magnet 17 located on the frontmost side of each plate-shaped third magnet 17 constituting the linear second magnet portion 7 ( Figure 1It can be seen from the leftmost plate-shaped third magnet 17 in the figure that the linear first magnet portion 5 and the linear second magnet portion 7 are arranged so that the front end of the lower side of the plate-shaped second magnet 15 on the front side is located at the center of the plate-shaped third magnet 17 on the front side. It should be noted that in the linear first magnet portion 5 and the linear second magnet portion 7, as long as the plate-shaped second magnet 15 and the plate-shaped third magnet 17 are staggered forward and backward with respect to each other in the vertical direction (in other words, as long as the plate-shaped second magnet 15 and the plate-shaped third magnet 17 do not overlap or coincide with each other in the vertical direction), the staggered ratio can be appropriately set according to the specifications, etc. In addition, although in the present embodiment, the linear second magnet portion 7 is staggered forward relative to the linear first magnet portion 5, it is of course also possible for the linear first magnet portion 5 to be staggered forward relative to the linear second magnet portion 7.

[0029] In this embodiment, since each plate-shaped second magnet 15 and each plate-shaped third magnet 17 are formed into the same shape, the plate-shaped second magnet 15 of the linear first magnet portion 5 and the plate-shaped third magnet 17 of the linear second magnet portion 7 facing the plate-shaped second magnet 15 have a positional relationship as described below.

[0030] That is, taking the frontmost plate-shaped second magnet 15 of the linear first magnet portion 5 as an example, the front half of the plate-shaped second magnet 15 ( Figure 1 The left half of the straight second magnet portion 7 and the rear half of the plate-shaped third magnet 17 on the front side ( Figure 1 The rear half of the plate-shaped second magnet 15 faces the plate-shaped third magnet 17 ( Figure 1 In other words, the planar second magnet 15 faces the two adjacent planar third magnets 17 (in an overlapping positional relationship when viewed in the vertical direction), and the planar third magnet 17 also faces the two adjacent planar second magnets 15.

[0031] In addition, in this embodiment, Figure 4 As shown in (b) and (c), when the moving part 3 is placed between the linear first magnet part 5 and the linear second magnet part 7 on the plane G, the height of the first center line C1 of the plate-shaped first magnet 9 of the moving part 3 is lower than the second center line C2 of the plate-shaped second magnet 15 of the linear first magnet part 5 ( Figure 4 (c) below the right end of the center line C2) and below the third center line C3 of the plate-shaped third magnet 17 of the linear second magnet portion 7 ( Figure 4 (b) below the right end of the center line C3). In this case, Figure 3As shown, a magnetic field is generated between the plate-shaped first magnet 9 and the plate-shaped second magnet 15 in the direction indicated by the arrow D ( Figure 3 A repulsive force (direction of the right oblique downward direction) is generated between the plate-shaped first magnet 9 and the plate-shaped third magnet 17 in the direction indicated by the arrow E ( Figure 3 As a result, as shown by arrow B, the movable portion 3 is pressed against the plane G. Since the movable portion 3 no longer floats from the plane G, the movable portion 3 is placed stably and horizontally on the plane G.

[0032] Next, based on the above structure, the function of this embodiment is described. Figure 5 As shown, at an appropriate first position between the linear first magnet portion 5 and the linear second magnet portion 7 on the plane G, for example, the position between the front and rear plate-shaped third magnets 17 and the plate-shaped second magnet 15 located therebetween ( Figure 5 The moving part 3 is placed (arranged) on the right side of the moving part 3. At this time, as described above, the moving part 3 is stably placed on the plane G, and the plate-shaped first magnet 9 of the moving part 3 is also perpendicular to the plane G (refer to Figure 3 ).

[0033] The front ends of the second plate-shaped magnet 15 and the third plate-shaped magnet 17 are tilted upward relative to the first plate-shaped magnet 9 and are offset from each other in the front-to-back direction. Therefore, the left side 17a of the third plate-shaped magnet 17 faces the right side 9b of the first plate-shaped magnet 9 (see FIG. Figure 4 (b)) is smaller than the range where the right side 15b of the plate-shaped second magnet 15 faces the left side 9a of the plate-shaped first magnet 9 (refer to Figure 4 (c)) (In other words, the exposed range (exposed area) of the right side surface 9b of the planar first magnet 9 that does not overlap with the planar third magnet 17 is larger than the exposed range of the left side surface 9a of the planar first magnet 9 that does not overlap with the planar second magnet 15.) As a result, the repulsive force CL between the planar first magnet 9 and the planar second magnet 15 is larger than the repulsive force CR between the planar first magnet 9 and the planar third magnet 17 (CL>CR).

[0034] In addition, since the front ends of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 are inclined upward relative to the plate-shaped first magnet 9, as shown in FIG. Figure 4 As shown in (c), on the left side 9a of the plate-shaped first magnet 9, the area where the rear side of the plate-shaped first magnet 9 faces the right side 15b of the plate-shaped second magnet 15 (the area of ​​the left side 9a of the plate-shaped first magnet 9 covered by the plate-shaped second magnet 15 when viewed in the vertical direction) is larger than the front side (in other words, the exposed area of ​​the left side 9a of the plate-shaped first magnet 9 is larger on the front side than on the rear side). Similarly, Figure 4 As shown in FIG. 1( b ), on the right side 9 b of the planar first magnet 9, the area where the rear side of the planar first magnet 9 faces the left side 17 a of the planar third magnet 17 (the area covered by the planar third magnet 17 on the right side 9 b of the planar first magnet 9, as viewed vertically) is larger than the front side (in other words, the exposed area of ​​the right side 9 b of the planar first magnet 9 is larger on the rear side than on the front side). As a result, the repulsive force CL between the planar first magnet 9 and the planar second magnet 15, and the repulsive force CR between the planar first magnet 9 and the planar third magnet 17, are stronger on the rear side of the planar first magnet 9 than on the front side. Therefore, the movable portion 3 to which the planar first magnet 9 is mounted moves in the forward direction indicated by arrow A.

[0035] Thereafter, when viewed in the vertical direction, the moving portion 3 reaches the second position ( Figure 5 When the movable part 3 is positioned at the center of the movable part 3 (in the middle of the movable part 3), the movable part 3 is also stably placed on the plane G as in the first position, and the planar first magnet 9 of the movable part 3 is also perpendicular to the plane G. In this second position, in contrast to the first position, the range where the right side 15b of the planar second magnet 15 faces the left side 9a of the planar first magnet 9 is smaller than the range where the left side 17a of the planar third magnet 17 faces the right side 9b of the planar first magnet 9 (in other words, the exposed range of the left side 9a of the planar first magnet 9 becomes larger than the exposed range of the right side 9b of the planar first magnet 9). Therefore, the repulsive force CR between the planar first magnet 9 and the planar third magnet 17 becomes greater than the repulsive force CL between the planar first magnet 9 and the planar second magnet 15 (CR>CL).

[0036] Furthermore, even in this second position, on the left side 9a of the planar first magnet 9, the rear side of the planar first magnet 9 faces the right side 15b of the planar second magnet 15 over a wider range than on the front side. Furthermore, on the right side 9b of the planar first magnet 9, the rear side of the planar first magnet 9 faces the left side 17a of the planar third magnet 17 over a wider range than on the front side. As a result, the repulsive force CL between the planar first magnet 9 and the planar second magnet 15, and the repulsive force CR between the planar first magnet 9 and the planar third magnet 17, are both stronger on the rear side of the planar first magnet 9 than on the front side. Consequently, the movable portion 3, to which the planar first magnet 9 is attached, moves in the forward direction indicated by arrow A.

[0037] Like this, Figure 5 As shown, the moving part 3 moves from the initial first position ( Figure 5 The first position is moved to the first second position ( Figure 5The first position is moved to the center of the moving part 3 in the middle of the moving part 3), and then moves to the second first position ( Figure 5 The left side moving portion 3 in the middle) and the second position (not shown) of the second time in front of the first position of the second time are repeated, thereby moving forward.

[0038] Here, the movable portion 3 is able to move due to the constant magnetic force generated by the plate-shaped first magnet 9 of the movable portion 3, the magnetic force generated by the plate-shaped second magnets 15 of the linear first magnet portion 5, and the magnetic force generated by the plate-shaped third magnets 17 of the linear second magnet portion 7. Therefore, if at least one of these magnets 9, 15, and 17 loses its magnetic force (demagnetization), for example, due to factors such as being heated to a temperature exceeding the Curie point, being subjected to strong external impact for a long period of time, or self-demagnetization, the factor (energy) that causes the movable portion 3 to move disappears, rendering the movable portion 3 unable to move. Therefore, it should be noted that the thrust generating mechanism 1 of this embodiment does not correspond to a so-called perpetual motion machine.

[0039] As described above, since each plate-shaped second magnet 15 of the linear first magnet portion 5 and each plate-shaped third magnet 17 of the linear second magnet portion 7 are tilted, the repulsive force CL between the plate-shaped first magnet 9 and the plate-shaped second magnet 15 and the repulsive force CR between the plate-shaped first magnet 9 and the plate-shaped third magnet 17 are stronger at the rear side of the plate-shaped first magnet 9 than at the front side, so that a forward thrust can be generated in the movable portion 3, and the movable portion 3 can be fully moved forward.

[0040] Furthermore, the movable portion 3 can be moved by a simple structure simply by tilting the second plate-shaped magnets 15 and the third plate-shaped magnets 17. Furthermore, by adjusting the tilt angles of the second plate-shaped magnets 15 and the third plate-shaped magnets 17, the moving force of the movable portion 3 can be adjusted.

[0041] Furthermore, since the positions of the linear first magnet portion 5 and the linear second magnet portion 7 are offset from each other in the front-to-back direction (the plate-shaped second magnets 15 constituting the linear first magnet portion 5 and the plate-shaped third magnets 17 constituting the linear second magnet portion 7 are offset from each other in the front-to-back direction), the repulsive forces CL and CR acting on both sides of the movable portion 3, which is interposed between these magnet portions 5 and 7 and moves forward, can be prevented from being unbalanced. As a result, the movable portion 3 can be prevented from being stopped by the balance of magnetic forces (the balance of magnetic forces can be prevented from acting as a brake on the movable portion 3), and smooth movement of the movable portion 3 can be achieved.

[0042] Furthermore, since each of the plate-shaped second magnets 15 and the plate-shaped third magnets 17 is formed into the same shape and tilted at the same predetermined angle, and since the plate-shaped second magnets 15 and the plate-shaped third magnets 17 of the linear first magnet portion 5 and the linear second magnet portion 7 are offset from each other in the front-to-back direction by half the horizontal length of the magnets, the distance from the initial first position to the initial second position (hereinafter referred to as the "first cycle"), the distance from the initial second position to the second first position (hereinafter referred to as the "second cycle"), and the distance from the second first position to the second second position (hereinafter referred to as the "third cycle") can be the same. Furthermore, since the degree of change in the repulsive forces CL and CR acting on the movable portion 3 can be the same in each of the first to third cycles, the movable portion 3 can move at a constant speed.

[0043] Next, based on Figure 6 The second embodiment will be described. In this description, the same components as those in the first embodiment will be marked with the same reference numerals to omit or simplify their description. This also applies to the embodiments and modifications described later. In addition, when describing the second embodiment, the description will focus on the differences between it and the first embodiment. It should be noted that Figure 6 It is a diagram schematically showing a thrust generating mechanism 30 according to the second embodiment.

[0044] like Figure 6 As shown in (a) and (b), the thrust generating mechanism (thrust generating device) 30 involved in the second embodiment includes: an annular first magnet portion (one side magnet portion) 31, which is placed on a plane G and forms a concentric ring; an annular second magnet portion (the other side magnet portion or the one side magnet portion) 33; an annular third magnet portion (the other side magnet portion) 35; moving portions 41, 42, which are located between the annular first magnet portion 31 and the annular second magnet portion 33; moving portions 43, 44, which are located between the annular second magnet portion 33 and the annular third magnet portion 35; and a moving direction limiting portion 51, which limits the moving direction of these moving portions 41, 42, 43, 44 (hereinafter, these may sometimes be collectively referred to as "moving portion 41, etc.").

[0045] like Figure 6As shown in FIG. 1( b ), the movement direction restricting portion 51 includes a rotating shaft 53 rotatably supported by a bearing (not shown) provided on plane G; and a rod-shaped support portion 55 extending from the upper end of the rotating shaft 53 parallel to plane G. The center portion of the support portion 55 is attached to the rotating shaft 53, with its ends positioned between the annular second magnet portion 33 and the annular third magnet portion 35. Furthermore, at each end of the support portion 55, there are provided hanging portions 63 and 64, respectively, which hang downwardly from these ends. At positions corresponding to the positions between the annular first magnet portion 31 and the annular second magnet portion 33, there are also provided hanging portions 61 and 62, respectively, which hang downwardly from these positions. The plate-shaped first magnet 9 described in the first embodiment is fixed to the lower ends of each of these hanging portions 61, 62, 63, and 64, with a predetermined gap relative to plane G (the plate-shaped first magnet 9 floats relative to plane G).

[0046] That is, the movable portion 41 is formed by the hanging portion 61 and the plate-shaped first magnet 9, the movable portion 42 is formed by the hanging portion 62 and the plate-shaped first magnet 9, the movable portion 43 is formed by the hanging portion 63 and the plate-shaped first magnet 9, and the movable portion 44 is formed by the hanging portion 64 and the plate-shaped first magnet 9. Then, the movement of the movable portion 41 and the like is restricted in the circumferential direction (rotational direction) centered on the rotating shaft 53 by the movement direction restriction portion 51 composed of the rotating shaft 53 and the support portion 55. As will be described later, the movable portion 41 and the like are moved along the circumferential direction (rotational direction) of the rotating shaft 53. Figure 6 The first direction indicated by the arrow F in (a) is the clockwise direction (right rotation direction).

[0047] like Figure 6 As shown in FIG. 1 , the annular first magnet portion 31 is formed into a ring centered on the rotation axis 53 by connecting a plurality of arc-shaped second magnets 65 bent into an arc shape. Specifically, the arc-shaped second magnets 65 are formed by bending an entire plate-shaped magnet along the annular first magnet portion 31 to form an arc shape, and each arc-shaped second magnet 65 constitutes a portion of the annular ring of the annular first magnet portion 31. Furthermore, in this embodiment, each arc-shaped second magnet 65 is formed to have the same shape as the others.

[0048] Specifically, if Figure 6 As shown in FIG. 2 , the annular first magnet portion 31 is configured such that the downstream side (in the direction of rotation of the moving portion 41) of the adjacent arc-shaped second magnets 65 and 65 is bonded or welded to the annular first magnet portion 31. Figure 6 The lower half of the rear surface of the arc-shaped second magnet 65 (left side in (c)) is fixed to the upstream side of the moving direction of the moving part 41 and the like (at the Figure 6(c) is the right side) and the front upper half of the arc-shaped second magnet 65 is connected to each other, and then a non-magnetic shell not shown is used to cover the periphery of these arc-shaped second magnets 65. It should be noted that Figure 6 In (c), for convenience of explanation, one pair of all the arc-shaped second magnets 65 constituting the annular first magnet portion 31 is shown.

[0049] observe Figure 6 (a) In each arc-shaped second magnet 65, the outer side surface (opposing surface on one side) 65a has the same north pole as the inner side surface (left side surface in the first embodiment) 9a of the plate-shaped first magnet 9 of the moving portion 41 and the inner side surface (left side surface in the first embodiment) 9a of the plate-shaped first magnet 9 of the moving portion 42, and the inner side surface 65b has the south pole. That is, Figure 6 As shown in (b), the outer side surface 65a of each arcuate second magnet 65 is capable of facing the inner side surface (one side surface) 9a of the plate-shaped first magnet 9 of the movable portion 41 and the inner side surface (one side surface) 9a of the plate-shaped first magnet 9 of the movable portion 42, which moves between the annular first magnet portion 31 and the annular second magnet portion 33 in the direction of arrow F, and has the same polarity as these inner side surfaces 9a, 9a. Therefore, a repulsive force is generated between the inner side surface 9a of the plate-shaped first magnet 9 of the movable portion 41 and the inner side surface 9a of the plate-shaped first magnet 9 of the movable portion 42 and the outer side surface 65a of the arcuate second magnet 65. In addition, when the annular first magnet portion 31 is placed on the plane G, the outer side surface 65a and the inner side surface 65b of each arcuate second magnet 65 are both perpendicular to the plane G.

[0050] like Figure 6 As shown in (c), the lower end of the rear end portion of each arc-shaped second magnet 65 (at Figure 6 (c) is the lower right corner) in contact with the plane G, and at the same time, the lower end of the front end of each arc-shaped second magnet 65 (at Figure 6 (c) is the lower left corner) in a state of floating from plane G. In other words, the front end of each arc-shaped second magnet 65 is tilted upward so that the inclination angle formed between the bottom surface of the arc-shaped second magnet 65 and plane G is a specified angle (acute angle). In addition, the inclination angles of each arc-shaped second magnet 65 are the same as each other. Therefore, when the annular first magnet portion 31 is placed on plane G, when viewed from the vertical direction, the fourth center line (the first center line on the fixed side) C4 passing through the center in the height direction of each arc-shaped second magnet 65 intersects and tilts with the first center line C1 of the plate-shaped first magnet 9 at a specified angle. In other words, the fourth center line C4 is tilted at a specified angle relative to plane G (the fourth center line C4 will not be parallel to the first center line C1).

[0051] like Figure 6 As shown in (a), the annular second magnet portion 33 is larger than the annular first magnet portion 31. The annular first magnet portion 33 is formed into an annular shape by connecting a plurality of arc-shaped second magnets 66 that are bent into an arc shape, thereby forming an annular shape centered on the rotating shaft 53. That is, the arc-shaped third magnet 66 is formed into an arc shape by bending the entire arc-shaped magnet along the annular second magnet portion 33, and each arc-shaped third magnet 66 constitutes a part of the annular ring of the annular second magnet portion 33. In addition, in this embodiment, the height of each arc-shaped third magnet 66 is the same as that of the arc-shaped second magnet 65, but is longer than the arc-shaped second magnet 65. In addition, these arc-shaped third magnets 66 are formed into the same shape as each other.

[0052] Specifically, if Figure 6 As shown in FIG. 2( c ), the annular second magnet portion 33 is configured such that the downstream side (in the direction of rotation of the moving portion 41 ) of the adjacent arc-shaped third magnets 66 , 66 is bonded or welded to the downstream side. Figure 6 The lower half of the rear surface of the arc-shaped third magnet 66 (left side in (c)) is fixed to the upstream side of the moving direction of the moving part 41 and the like (at the Figure 6 (c) is the right side) and the front upper half of the arc-shaped third magnet 66 is connected to each other, and then the periphery of these arc-shaped third magnets 66 is covered with a non-magnetic shell not shown. It should be noted that Figure 6 In (c), for convenience of explanation, one pair of all the arc-shaped third magnets 66 constituting the annular second magnet portion 33 is shown.

[0053] observe Figure 6 (a) In each arc-shaped third magnet 66, the outer side surface (opposing surface on one side) 66a has the same north pole as the inner side surface 9a of the plate-shaped first magnet 9 of the moving portion 43 and the inner side surface 9a of the plate-shaped first magnet 9 of the moving portion 44, and the inner side surface (opposing surface on the other side) 66b has the same south pole as the outer side surface (right side surface in the first embodiment) 9a of the plate-shaped first magnet 9 of the moving portion 41 and the outer side surface (right side surface in the first embodiment) 9a of the plate-shaped first magnet 9 of the moving portion 42. That is, as Figure 6As shown in FIG. 1( b ), the outer side surface 66a of each arcuate third magnet 66 is capable of facing the inner side surface (one side surface) 9a of the plate-shaped first magnet 9 of the movable portion 43 and the inner side surface (one side surface) 9a of the plate-shaped first magnet 9 of the movable portion 44, which moves in the direction of arrow F between the annular second magnet portion 33 and the annular third magnet portion 35, and has the same polarity as the inner side surfaces 9a, 9a. Furthermore, the inner side surface 66b of each arcuate second magnet 66 is capable of facing the outer side surface (the other side surface) 9b of the plate-shaped first magnet 9 of the movable portion 41 and the outer side surface (the other side surface) 9b of the plate-shaped first magnet 9 of the movable portion 42, which moves in the direction of arrow F between the annular first magnet portion 31 and the annular second magnet portion 33, and has the same polarity as the outer side surfaces 9b, 9b. Therefore, repulsive forces are generated between the inner side surfaces 9a of the plate-shaped first magnets 9 of the moving portion 43 and the inner side surfaces 9a of the plate-shaped first magnets 9 of the moving portion 44 and the outer side surfaces 66a of the arcuate third magnets 66, and between the outer side surfaces 9b of the plate-shaped first magnets 9 of the moving portion 41 and the outer side surfaces 9b of the plate-shaped first magnets 9 of the moving portion 42 and the inner side surfaces 66b of the arcuate third magnets 66. Furthermore, when the annular second magnet portion 33 is placed on the plane G, the outer side surface 65a and the inner side surface 66b of each arcuate third magnet 66 are perpendicular to the plane G.

[0054] like Figure 6 As shown in (c), the lower end of the rear end portion of each arc-shaped third magnet 66 (at Figure 6 (c) is the lower right corner) in contact with the plane G, and at the same time, the lower end of the front end of each arc-shaped third magnet 66 (at Figure 6 (c) is the lower left corner) in a state of floating from plane G. In other words, the front end of each arc-shaped third magnet 66 is tilted upward so that the inclination angle formed between the bottom surface of these arc-shaped third magnets 66 and plane G is a specified angle (acute angle). In addition, the inclination angles of each arc-shaped third magnet 66 are the same. Therefore, when the annular second magnet portion 33 is placed on plane G, when viewed from the vertical direction, the fifth center line (the first center line on the fixed side or the second center line on the fixed side) C6 passing through the center in the height direction of each arc-shaped third magnet 66 intersects and tilts with the first center line C1 of the plate-shaped first magnet 9 at a specified angle. In other words, the fourth center line C4 is tilted at a specified angle relative to plane G (the fourth center line C4 will not be parallel to the first center line C1). It should be noted that in this embodiment, the inclination angle of the arc-shaped third magnet 66 is the same as the inclination angle of the above-mentioned arc-shaped second magnet 65.

[0055] like Figure 6As shown in (a), the annular third magnet portion 35 is larger than the annular second magnet portion 33. The annular third magnet portion 35 is formed into an annular shape by connecting a plurality of arc-shaped fourth magnets 67 bent into an arc shape, thereby forming an annular shape centered on the rotating shaft 53. That is, the arc-shaped fourth magnet 67 is formed into an arc shape by bending the entire arc-shaped magnet along the annular third magnet portion 35, and each arc-shaped fourth magnet 67 constitutes a part of the annular ring of the annular third magnet portion 35. In addition, in this embodiment, the height of each arc-shaped fourth magnet 67 is the same as that of the arc-shaped third magnet 66, but is longer than the arc-shaped third magnet 66. In addition, these arc-shaped fourth magnets 67 are formed into the same shape as each other.

[0056] Specifically, if Figure 6 As shown in FIG. 2 , the annular third magnet portion 35 is configured such that the downstream side (in the direction of rotation of the moving portion 41) of the adjacent arc-shaped fourth magnets 67, 67 is bonded or welded to the downstream side. Figure 6 The lower half of the front face of the arc-shaped fourth magnet 67 (left side in (c)) is fixed to the upstream side of the moving direction of the moving part 41 and the like (at the Figure 6 (c) is the right side) and the upper half of the back of the arc-shaped fourth magnet 67 is connected to each other, and then a non-magnetic shell not shown is used to cover the periphery of these arc-shaped fourth magnets 67. It should be noted that Figure 6 In (c), for the sake of convenience, a pair of all the arc-shaped fourth magnets 67 constituting the annular third magnet portion 35 is shown. Figure 6 In (c), as described above, the arcuate second magnet 65, the arcuate third magnet 66, and the arcuate fourth magnet 67 differ only in length. Therefore, for ease of explanation, these magnets 65, 66, and 67 are shown in the same figure.

[0057] observe Figure 6(a) In each arcuate fourth magnet 67, the outer side surface (opposing surface on one side) 67a has an N-pole, while the inner side surface (opposing surface on the other side) 67b has an S-pole, which is the same as the outer side surface 9b of the plate-shaped first magnet 9 of the movable portion 43 and the outer side surface 9b of the plate-shaped first magnet 9 of the movable portion 44. Specifically, the inner side surface 67b of each arcuate fourth magnet 67 is able to face the outer side surface 9b of the plate-shaped first magnet 9 of the movable portion 43 and the outer side surface 9b of the plate-shaped first magnet 9 of the movable portion 44, which moves in the direction of arrow F between the annular second magnet portion 33 and the annular third magnet portion 35, and has the same polarity as the outer side surfaces 9b and 9b. Therefore, a repulsive force is generated between the outer side surfaces 9b of the plate-shaped first magnet 9 of the movable portion 43 and the outer side surfaces 9b of the plate-shaped first magnet 9 of the movable portion 44 and the inner side surface 67b of the arcuate fourth magnet 67. Furthermore, when the annular third magnet portion 35 is placed on the plane G, the outer side surface 65 a and the inner side surface 67 b of each arc-shaped fourth magnet 67 are perpendicular to the plane G.

[0058] like Figure 6 As shown in (c), the lower end of the rear end portion of each arc-shaped fourth magnet 67 (at Figure 6 (c) is the lower right corner) and contacts the plane G, and at the same time, the lower end of the front end of each arc-shaped fourth magnet 67 (at Figure 6 (c) is the lower left corner) in a state of floating from plane G. In other words, the front end of each arc-shaped fourth magnet 67 is tilted upward so that the inclination angle formed between the bottom surface of these arc-shaped fourth magnets 67 and plane G is a specified angle (acute angle). In addition, the inclination angle of each arc-shaped fourth magnet 67 is the same as each other. Therefore, when the annular third magnet portion 35 is placed on plane G, when viewed from the vertical direction, the sixth center line (the second center line on the fixed side) C6 passing through the height center of each arc-shaped fourth magnet 67 intersects and tilts at a specified angle with the first center line C1 of the plate-shaped first magnet 9. In other words, the fourth center line C4 is tilted at a specified angle relative to plane G (the fourth center line C4 will not be parallel to the first center line C1). It should be noted that in this embodiment, the inclination angle of the arc-shaped fourth magnet 67 is the same as the inclination angle of the above-mentioned arc-shaped second magnet 65 and arc-shaped third magnet 66.

[0059] Next, the positional relationship between the arc-shaped second magnets 65 of the annular first magnet portion 31, the arc-shaped third magnets 66 of the annular second magnet portion 33, and the arc-shaped fourth magnets 67 of the annular third magnet portion 35 will be described. However, for the sake of convenience, Figure 6In (a), a particular arcuate second magnet 65 is designated by reference numeral X1, and the arcuate second magnet 65 adjacent to the downstream side of the arcuate second magnet X1 as indicated by arrow F (hereinafter referred to as the "downstream side" and the upstream side as indicated by arrow F as the "upstream side") is designated by reference numeral X2. Furthermore, the arcuate third magnets 66 of the annular second magnet portion 33 that overlap at least a portion of the arcuate second magnets X1 and X2 and are adjacent to each other as viewed in the vertical direction are designated by reference numerals Y1, Y2, and Y3, respectively. The arcuate fourth magnets 67 of the annular third magnet portion 35 that overlap at least a portion of the arcuate third magnets Y1, Y2, and Y3 and are adjacent to each other as viewed in the vertical direction are designated by reference numerals Z1, Z2, Z3, and Z4, respectively, and will be described below.

[0060] like Figure 6 As shown in FIG. 1 , the annular first magnet portion 31 and the annular second magnet portion 33 are arranged concentrically with each other so as to be parallel to and face each other on a plane G, with a predetermined interval therebetween. Furthermore, the annular second magnet portion 33 and the annular third magnet portion 35 are also arranged concentrically with each other so as to be parallel to and face each other on a plane G, with the same predetermined interval therebetween.

[0061] In this state, the arcuate second magnet X1 of the annular first magnet portion 31 is positioned such that, as viewed in the vertical direction, its left end a is positioned between the left end e and right end f of the arcuate third magnet Y1 of the annular second magnet portion 33 (approximately at the center between the left and right ends e and f), and its right end b is positioned between the left end g and right end h of the arcuate third magnet Y2 adjacent to the downstream side of the arcuate third magnet Y1 (approximately at the center between the left and right ends g and h). Furthermore, the arcuate second magnet X2 adjacent to the downstream side of the arcuate second magnet X1 is positioned such that, as viewed in the vertical direction, its left end c is positioned between the left end g and right end h of the arcuate third magnet Y2 adjacent to the downstream side of the arcuate third magnet Y1 (approximately at the center between the left and right ends g and h), and its right end d is positioned between the left end i and right end j of the arcuate third magnet Y3 adjacent to the downstream side of the arcuate third magnet Y2 (approximately at the center between the left and right ends i and j).

[0062] Furthermore, the arcuate third magnet Y1 of the annular second magnet portion 33 is arranged such that, as viewed in the vertical direction, its left end e is located between the left end k and right end l of the arcuate fourth magnet Z1 of the annular third magnet portion 37 (approximately at the center between the left and right ends k and l), and its right end f is located between the left end m and right end n of the arcuate fourth magnet Z2 adjacent to the downstream side of the arcuate fourth magnet Z1 (approximately at the center between the left and right ends m and n). Furthermore, the arcuate third magnet Y2 adjacent to the downstream side of the arcuate third magnet Y1 is arranged such that, as viewed in the vertical direction, its left end g is located between the left end m and right end n of the arcuate fourth magnet Z2 adjacent to the downstream side of the arcuate fourth magnet Z1 (approximately at the center between the left and right ends m and n), and its right end h is located between the left end o and right end p of the arcuate fourth magnet Z3 adjacent to the downstream side of the arcuate fourth magnet Z2 (approximately at the center between the left and right ends o and p). In addition, the arc-shaped third magnet Y3 adjacent to the downstream side of the arc-shaped third magnet Y2 is configured so that, when viewed in the vertical direction, its left end i is located between the left end o and the right end p of the arc-shaped fourth magnet Z3 (approximately in the center of the left and right ends o and p), and its right end j is located between the left end q and the right end r of the arc-shaped fourth magnet Z4 adjacent to the downstream side of the arc-shaped fourth magnet Z3 (approximately in the center of the left and right ends q and r).

[0063] Thus, for example, the arc-shaped second magnet X1 is arranged to span between the arc-shaped third magnets Y1 and Y2 when viewed in the vertical direction, so that the upstream side portion ( Figure 6 (a) and the downstream side of the arc-shaped third magnet Y1 ( Figure 6 The arcuate third magnet Y1 and the arcuate fourth magnet Z2 are arranged such that the upstream portion of the arcuate third magnet Y1 and the downstream portion of the arcuate fourth magnet Z1 face each other, and the downstream portion of the arcuate third magnet Y1 and the upstream portion of the arcuate fourth magnet Z2 face each other. Furthermore, for example, the arcuate third magnet Y1 is arranged so as to span between the arcuate fourth magnets Z1 and Z2 when viewed in the vertical direction, so that the upstream portion of the arcuate third magnet Y1 and the downstream portion of the arcuate fourth magnet Z1 face each other, and the downstream portion of the arcuate third magnet Y1 and the upstream portion of the arcuate fourth magnet Z2 face each other.

[0064] That is, the positional relationship between the annular first magnet portion 31 and the annular second magnet portion 33 is configured so that, as viewed in the vertical direction, the ends of the arcuate third magnets 66 of the annular second magnet portion 33 are circumferentially offset from the ends of the arcuate second magnets 65 of the annular first magnet portion 31. Furthermore, the positional relationship between the annular second magnet portion 33 and the annular third magnet portion 35 is configured so that, as viewed in the vertical direction, the ends of the arcuate fourth magnets 67 of the annular third magnet portion 35 are circumferentially offset from the ends of the arcuate third magnets 66 of the annular second magnet portion 33. It should be noted that, similar to the above-mentioned first embodiment, for each arc-shaped second magnet 65, arc-shaped third magnet 66, and arc-shaped fourth magnet 67 of the annular first magnet portion 31, the annular second magnet portion 33, and the annular third magnet portion 35, it is sufficient that they are staggered in the circumferential direction when viewed from the vertical direction (in other words, it is sufficient that at least one of the two ends of the arc-shaped second magnet 65 facing each other does not overlap or coincide with at least one of the two ends of the arc-shaped third magnet 66, and at least one of the two ends of the arc-shaped third magnet 66 does not overlap or coincide with each other, and at least one of the two ends of the arc-shaped third magnet 66 facing each other does not overlap or coincide with at least one of the two ends of the arc-shaped fourth magnet 67), and the staggered ratio can be appropriately set according to specifications, etc.

[0065] In addition, if Figure 6 As shown in (c), in this embodiment, as in the first embodiment, when viewed in the vertical direction, the first center line C1 of the plate-shaped first magnet 9 of the movable portion 41 and the like located at a position with a gap from the plane G is arranged to be lower than the fourth center line C4 of each arc-shaped second magnet 65 of the annular first magnet portion 31, lower than the fifth center line C5 of each arc-shaped third magnet 66 of the annular second magnet portion 33, and lower than the sixth center line C6 of each arc-shaped fourth magnet 67 of the annular third magnet portion 35. Therefore, as in the first embodiment, Figure 3 As described in the figure, a repulsive force acts between the annular first magnet portion 31 and the annular second magnet portion 33 to push the movable portions 41 and 42 toward the plane G (see arrow B). A repulsive force also acts between the annular second magnet portion 33 and the annular third magnet portion 35 to push the movable portions 43 and 44 toward the plane G. As a result, the movable portion 41 and the like remain in a stable state, no longer floating above the plane G.

[0066] In the present embodiment having such a structure, similarly to the first embodiment, the front ends of the arc-shaped second magnet 65, the arc-shaped third magnet 66, and the arc-shaped fourth magnet 67 are all tilted upward relative to the plate-shaped first magnet 9 of the moving portion 41, etc., and they are staggered in the circumferential direction. Figure 6(a) moves in the direction of the arrow F shown (rotates around the rotating shaft 53), achieving the same action and effect as the first embodiment. In addition, in the second embodiment, since the rotating shaft 53 rotates only by magnetic force (repulsive force), as long as the rotating shaft 53 continues to rotate by magnetic force, it is possible to generate electricity by extracting electrical energy from the rotation of the rotating shaft 53 (the energy generated by the rotation can be converted into electrical energy). It should be noted that in this embodiment, as in the above-mentioned first embodiment, when at least one of the plate-shaped first magnet 9, the arc-shaped second magnet 65, the arc-shaped third magnet 66, and the arc-shaped fourth magnet 67 loses its magnetic force for some reason, the moving part 41, etc. will become immobile. Therefore, it is explained here that the thrust generating device 30 according to this embodiment does not correspond to a so-called perpetual motion machine.

[0067] The present invention is not limited to the above-described embodiments, and appropriate changes can be made without departing from the spirit and scope of the present invention.

[0068] For example, in the first embodiment, the movable portion 3 is moved by a linear first magnet portion 5 comprising a plurality of plate-shaped second magnets 15 and a linear second magnet portion 7 comprising a plurality of plate-shaped third magnets 17. However, the thrust generating device 1 may alternatively be configured by a single plate-shaped second magnet 15, a single plate-shaped third magnet 17 disposed so as to be offset from the plate-shaped second magnet 15 in both the front-to-back directions, and the movable portion 3. Even in this case, the movable portion 3 can be moved. Furthermore, in this case, the front-to-back length of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 is preferably at least twice the front-to-back length of the plate-shaped first magnet 9 of the movable portion 3. This also applies to the second embodiment.

[0069] In the first embodiment described above, each of the plate-shaped second magnets 15 and the plate-shaped third magnets 17 has the same shape and is tilted at the same predetermined angle. However, by making the shape and size of some of the second magnets (or some of the third magnets) different from the shape and size of the other second magnets (or other third magnets), or by making the tilt angle of some of the second magnets (or third magnets) different from the tilt angle of the other second magnets (or other third magnets), the speed of the moving unit 3 can be changed even during movement. In other words, by changing the shape, size, or tilt angle of some of the second magnets or third magnets, the behavior related to the movement of the moving unit 3 can be adjusted. This also applies to the second embodiment.

[0070] Furthermore, while the second embodiment uses a plate-shaped first magnet 9, an arcuate first magnet may be used in which the entire plate-shaped first magnet 9 is bent into an arcuate shape along the annular first magnet portion 31. In this case, regardless of the position of the arcuate first magnet between the annular first magnet portion 31 and the annular second magnet portion 33 (between the annular second magnet portion 33 and the annular third magnet portion 35), the distance between the arcuate first magnet and the arcuate second magnet 65 of the annular first magnet portion 31 (the distance between the arcuate first magnet and the arcuate third magnet 66 of the annular second magnet portion 33), and the distance between the arcuate first magnet and the arcuate second magnet 66 of the annular second magnet portion 33 (the distance between the arcuate fourth magnet 67 of the arcuate third magnet portion 35) are always the same, thereby making the movement of the moving portion 41 and the like smoother.

[0071] Next, based on Figure 7 Modification 1 of the first embodiment will now be described. This modification 1 differs from the first embodiment primarily in that the individual plate-shaped second magnets 15 constituting the linear first magnet portion 5 are separated from one another, and the individual plate-shaped third magnets 17 constituting the linear second magnet portion 7 are also separated from one another.

[0072] like Figure 7 As shown in (a), a plurality of plate-shaped second magnets 15 are arranged at equal intervals from each other, and a plurality of plate-shaped third magnets 17 are arranged at equal intervals from each other. Figure 7 As shown in FIG. 2( b ), the positional relationship between the plurality of plate-shaped second magnets 15 and the plurality of plate-shaped third magnets 17 is as follows: when viewed from the vertical direction, the plate-shaped second magnets 15 (e.g., Figure 7 The leftmost plate-shaped second magnet 15 in (a), hereinafter referred to as the "leftmost plate-shaped second magnet 15", is located between the plate-shaped third magnet 17 located on the downstream side of the adjacent plate-shaped third magnets 17 and 17 (for example, Figure 7 (a) between the leftmost plate-shaped third magnet 17, hereinafter referred to as the "leftmost plate-shaped third magnet 17") and the plate-shaped third magnet 17 located on the downstream side among the adjacent plate-shaped third magnets 17, 17 (for example, the central plate-shaped third magnet 17 adjacent to the leftmost plate-shaped third magnet 17, hereinafter referred to as the "central plate-shaped third magnet 17") (between the adjacent plate-shaped third magnets 17, 17). Based on this positional relationship, as Figure 7As shown in (b), when viewed vertically, the downstream end of the leftmost plate-shaped second magnet 15 and the upstream end of the leftmost plate-shaped third magnet 17 overlap, and the upstream end of the leftmost plate-shaped second magnet 15 and the downstream end of the center plate-shaped third magnet 17 overlap, forming an "overlapping positional relationship." Even with this structure, the same functions and effects as those of the first embodiment can be achieved. Of course, it should be noted that the multiple plate-shaped second magnets 15 and the multiple plate-shaped third magnets 17 can also be arranged at unequal intervals.

[0073] It is also important to note that although Figure 7 In (a) and (b), the positional relationship between the plurality of plate-shaped second magnets 15 and the plurality of plate-shaped third magnets 17 is "overlapping positional relationship", but it is not limited thereto and may also be Figure 7 (c), (d) or 7 (e), (f) shown in the positional relationship, and with these structures, the same action and effect as the first embodiment can be achieved. Figure 7 As shown in (c) and (d), when viewed from the vertical direction, the rear end surface of the leftmost plate-shaped third magnet 17 (observation Figure 7 (c), the right end face of the leftmost plate-shaped third magnet 17) and the front end face of the leftmost plate-shaped second magnet 15 (observation Figure 7 (c) The left end face of the leftmost plate-shaped second magnet 15 is in surface contact, and when viewed from the vertical direction, the front end face of the centermost plate-shaped third magnet 17 is in surface contact with the rear end face of the leftmost plate-shaped second magnet 15. Such a "non-overlapping positional relationship" is also possible. In addition, as Figure 7 As shown in (e) and (f), when viewed in the vertical direction, the rear end surface of the leftmost plate-shaped third magnet 17 and the front end surface of the leftmost plate-shaped second magnet 15 are separated from each other, and the front end surface of the central plate-shaped third magnet 17 and the rear end surface of the leftmost plate-shaped second magnet 15 are separated from each other. In other words, there is a certain distance between the adjacent plate-shaped third magnets 17, 17 and the plate-shaped second magnet 15 located between the plate-shaped third magnets 17, 17 in the vertical direction. Such a "spaced positional relationship" is also possible.

[0074] Next, based on Figure 8 , a modification example 1 of the second embodiment is described. In the modification example 1 of the second embodiment, although an annular first magnet portion 31 and an annular second magnet portion 33 are provided, no Figure 6The example of the annular third magnet portion 35 shown. Furthermore, in Modification 1 of the second embodiment, generally speaking, the "overlapping positional relationship," "non-overlapping positional relationship," and "spaced positional relationship" in Modification 1 of the first embodiment described above are applied to the second embodiment, and the positional relationship between the plurality of arcuate second magnets 65 of the annular first magnet portion 31 and the plurality of arcuate third magnets 66 of the annular second magnet portion 33 will be mainly described.

[0075] like Figure 8 As shown in (a) to (c), the plurality of arc-shaped second magnets 65 are arranged at equal intervals from each other, and the plurality of arc-shaped third magnets 66 are also arranged at equal intervals from each other, and when viewed from the vertical direction ( Figure 8 (The illustration when viewed from the vertical direction is omitted in the figure), the positional relationship is: the arc-shaped second magnet 65 is located between the adjacent arc-shaped third magnets 66, 66. Similar to the first modification of the first embodiment, the types of positional relationships between the plurality of arc-shaped second magnets 65 and the plurality of arc-shaped third magnets 66 based on this positional relationship are: Figure 8 (a) "has overlapping positional relationship", Figure 8 (b) shows a "non-overlapping positional relationship", Figure 8 (c) shows a "positional relationship with a gap".

[0076] That is, in 8(a), an "overlapping positional relationship" is shown: the downstream end of the arc-shaped second magnet 65 overlaps with the upstream end of the arc-shaped third magnet 66 located on the downstream side of the adjacent arc-shaped third magnets 66, 66, and the upstream end of the arc-shaped second magnet 65 overlaps with the downstream end of the arc-shaped third magnet 66 located on the upstream side of the adjacent arc-shaped third magnets 66, 66. Figure 8 (b) shows a "non-overlapping positional relationship": the rear end face of the arc-shaped third magnet 66 on the downstream side and the front end face of the arc-shaped second magnet 65 are in surface contact with each other when viewed in the vertical direction, and the front end face of the arc-shaped third magnet 66 on the upstream side and the rear end face of the arc-shaped second magnet 65 are in surface contact with each other when viewed in the vertical direction. Figure 8 (c) illustrates a "spaced positional relationship": when viewed in the vertical direction, adjacent arcuate third magnets 66, 66 are spaced apart from the arcuate second magnet 65 located between them. Even with this first variation of the second embodiment, the same functions and effects as those of the second embodiment can be achieved.

[0077] Next, based on Figure 9 , a modification example 2 of the first embodiment is described. Figure 9 As shown in (a) and (b), the positional relationship between the planar second magnet 15 and the planar third magnet 17 is the "overlapping positional relationship" described above. Furthermore, by attaching a planar first additional magnet 71, which is shorter than the planar second magnet 15, and a second additional magnet 73, which is shorter than the first additional magnet 71, to the downstream end of the left side 15a of the planar second magnet 15, overlapping them in this order, the magnetic force on the downstream side of the planar second magnet 15 becomes stronger than the magnetic force on the upstream side. It should be noted that the front end surface of each of the first additional magnet 71 and the second additional magnet 73 is flush with the front end surface of the planar second magnet 15. Similarly, by attaching a planar third additional magnet 75, which is shorter than the planar third magnet 17, and a fourth additional magnet 77, which is shorter than the third additional magnet 75, to the downstream end of the left side 17a of the planar third magnet 17, overlapping them in this order, the magnetic force on the downstream side of the planar third magnet 17 becomes stronger than the magnetic force on the upstream side. It should be noted that the front end surface of each of the third additional magnet 75 and the fourth additional magnet 77 is flush with the front end surface of the plate-shaped third magnet 17 .

[0078] In this manner, in the plate-shaped second magnet 15 and the plate-shaped third magnet 17 in the "overlapping positional relationship", since the plate-shaped second magnet 15 is configured such that the magnetic force on the downstream side is stronger than the magnetic force on the upstream side, when the moving part 3 having the plate-shaped first magnet 9 reaches between the upstream end of the plate-shaped third magnet 17 and the downstream end of the plate-shaped second magnet 15 ( Figure 9 When the plate-shaped first magnet 9 is positioned between the upstream end of the left plate-shaped third magnet 17 and the downstream end of the left plate-shaped second magnet 15 in (a), the plate-shaped first magnet 9 receives a repulsive force from the plate-shaped second magnet 15 and the plate-shaped third magnet 17, and this repulsive force is greater on the downstream side of the plate-shaped first magnet 9 than on the upstream side. In other words, in the movable portion 3 whose movement direction is restricted to the direction of arrow A, because the repulsive force received at the rear end side in this movement direction is greater than the repulsive force received at the front end side in this movement direction, the movable portion 3 is pushed out in the direction of arrow A where movement is restricted, and can move more strongly in the direction of arrow A.

[0079] It should be noted that in order to enhance the magnetic force of the downstream end of the plate-shaped second magnet 15 and the plate-shaped third magnet 17, it is not limited to setting Figure 9 The first additional magnet 71, the second additional magnet 73, the third additional magnet 75 and the fourth additional magnet 77 shown in (a) are, for example, Figure 9As shown in (b), the magnetic force of the downstream ends of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 can also be enhanced by changing the shapes of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 so that the thickness of each downstream end portion of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 is greater than the thickness of each upstream end portion thereof.

[0080] In addition, if Figure 9 (b) shows that Figure 9 The second plate-shaped magnet 15 and the third plate-shaped magnet 17 shown in (a) are similar. In the first plate-shaped magnet 9, the thickness of the upstream end of the first plate-shaped magnet 9 can be made thicker than the thickness of the downstream end (by forming a tapered shape), thereby increasing the magnetic force of the upstream end of the first plate-shaped magnet 9. In this way, the moving part 3 can move more strongly in the direction of arrow A. In addition, regarding the first plate-shaped magnet 9, in addition to the Figure 9 (b) In addition to the examples shown, for example, Figure 9 As shown in (c), as the plate-shaped first magnet 9, it is also possible to use a structure in which additional magnets 91 to 97 shorter than the plate-shaped first magnet 9 are overlapped at the center of both side surfaces of the plate-shaped first magnet 9. Figure 9 In the example shown in (c), the magnetic force at both ends of the plate-shaped first magnet 9 is designed to be weaker than the magnetic force at the center. However, at least one of the magnetic forces at both ends of the plate-shaped first magnet 9 may be weaker than the magnetic force at the center (for Figure 9 The first magnet 9 shown in (b) can also be said to have a weaker magnetic force at its upstream end than at its center).

[0081] In addition, although in the above-mentioned first embodiment and second embodiment and each modification, as Figure 3 、 Figure 4 as well as Figure 10 As shown in FIG. 1 and FIG. 2 , the plate-shaped first magnet 9 is designed to be parallel to the plane G when the moving part 3 is placed on the plane G, but the present invention is not limited thereto. The plate-shaped first magnet 9 may also be designed to be inclined relative to the plane G (inclined at an angle such that the plate-shaped first magnet 9 is not parallel to the first direction). Specifically, as shown in FIG. Figure 10 As shown in (a), in this figure, the left wheel 13a of the plate-shaped first magnet 9 (moving part 3) is made larger than the right wheel 13 so as to be tilted to the upper right in the figure, or as shown in Figure 10 As shown in (c), in this figure, the left wheel 13a of the plate-shaped first magnet 9 (moving portion 3) may be made larger than the right wheel 13 so as to be inclined toward the upper left in the figure.

[0082] like Figure 10As shown in (b), the first center line (moving side center line) C1 of the plate-shaped first magnet 9 parallel to the plane G passes through the center of the diagonal line of the rectangular plate-shaped first magnet 9 in the figure. In other words, it passes through the center of the highest position and the lowest position of the plate-shaped first magnet 9. Figure 10 As shown in (a) and (c), when the plate-shaped first magnet 9 is tilted relative to the plane G, the first center line C1 passes through the highest position of the plate-shaped first magnet 9 ( Figure 10 (a) The upper left corner of the first magnet 9, Figure 10 (c) the upper right corner of the first magnet 9) and the lowest position of the plate-shaped first magnet 9 ( Figure 10 (a) The lower right corner of the first magnet 9, Figure 10 (c) is the center of the lower left corner of the first magnet 9). Figure 10 As shown in (a) to (c), regardless of whether the first magnet 9 is parallel to or inclined with respect to plane G, the first center line C1 remains the same, and the relationship between the first center line C1 and the second to sixth center lines remains unchanged. Even with this configuration, the same functions and effects as those of the aforementioned embodiments and variations can be achieved.

[0083] In each of the above-mentioned embodiments and modifications, the first magnet is in an upright state relative to the plane G. In other words, Figure 3 The peripheral surface of the plate-shaped first magnet 9 shown (for example, Figure 3 The lower surface of the plate-shaped first magnet 9 is parallel to and faces the plane G, and the two side surfaces 9a and 9b of the plate-shaped first magnet 9 are oriented in a direction parallel to the plane G (for example, Figure 3 In other words, as for the positional relationship between the first to third magnets, although generally speaking, any one of the first to third magnets is in a positional relationship in a generally upright position (for example, Figure 3 The positional relationship of the plate-shaped first magnet 9, the plate-shaped second magnet 15, and the plate-shaped third magnet 17 is shown in FIG. 1 , but it can also be changed, such as Figure 11 As shown, the second and third magnets are in an upright position, but the first magnet is in a horizontal position.

[0084] For example, Figure 11As shown in (a), as an example of the first magnet mounted on the moving part 3, a disk-shaped disk magnet 110 can be used, and a magnet 120 formed by stacking a plurality of the disk-shaped magnets 110 can be used. By stacking a plurality of disk-shaped magnets 110 so as to bond them to each other by magnetic force (adjacent disk-shaped magnets 110 are attracted to each other and in close contact), the magnet 120 forms an integrated cylindrical shape. In addition, in addition to being bonded to each other by magnetic force between the plurality of disk-shaped magnets 110, the magnet 120 can also be bonded by an adhesive or further reinforced by a fixing tool such as a screw. In addition, as the magnet 120, instead of using a disk-shaped magnet, an integrated cylindrical shape can be formed by stacking plate-shaped magnets, and its shape can be appropriately changed.

[0085] Among the plurality of disk-shaped magnets 110 constituting the magnet 120, the disk-shaped magnet 110 constituting one end portion of the magnet 120 (at Figure 11 The surface 110a on one side of the disk-shaped magnet 110 (the uppermost disk-shaped magnet 110 in FIG. 11a ) has a magnetic pole of the N pole (first polarity) and constitutes the surface 120a on one side of the magnet 120 (one end surface). Among the plurality of disk-shaped magnets 110 constituting the magnet 120, the disk-shaped magnet 110 (the upper end surface in FIG. 11a ) constituting the other end of the magnet 120 Figure 11 (a) is the other side of the bottom disk-shaped magnet 110) (at Figure 11 (a) The lower end surface 110b has a magnetic pole with an S pole (second polarity) and constitutes the other side surface (other end surface) 120b of the magnet 120. Each outer peripheral surface 110c of the plurality of disk-shaped magnets 110 constitutes the outer peripheral surface 120c of the magnet 120. It should be noted that in the following description, one end surface and the other end surface of the disk-shaped magnet 110 may sometimes be collectively referred to as the two end surfaces.

[0086] It should be noted that Figure 11 The symbol MC in (a) represents the direction perpendicular to the height of the magnet 120 ( Figure 11 (a) the up and down direction) Figure 11 The center line passing through the center of the magnet 120 as viewed in the left-right direction (a), in other words, the symbol MC represents the boundary line (hereinafter referred to as the boundary line MC) between the north pole and the south pole of the central disk-shaped magnet 110 among the multiple disk-shaped magnets 110 constituting the magnet 120. Figure 11 The plane G in (a) is shown to facilitate understanding of the flat state of the disc-shaped magnet 110 .

[0087] The magnetic poles of the magnet 120 are actually measured using a measuring instrument such as a magnetic detector for measuring the magnetic poles. The results are as follows: Figure 11As shown in (b), in the outer peripheral surface 120c of the magnet 120, the range R1 from the surface 120a on one side of the magnet 120 to the boundary line MC has the polarity of the N pole, and the range R2 from the surface 120b on the other side of the magnet 120 to the boundary line MC has the polarity of the S pole. In other words, in the outer peripheral surface of the magnet 120, the upper half area R1 is the N pole, and the lower half area R2 is the S pole. Therefore, by Figure 1 The plate-shaped second magnet 15 shown in FIG. Figure 1 The moving part 3 starts to move along the region R1 on the outer peripheral surface of the magnet 120. Figure 1 Move in the direction of arrow A. Similarly, by Figure 1 The plate-shaped third magnet 17 shown in FIG. Figure 1 The moving part 3 starts to move along the region R2 on the outer peripheral surface of the magnet 120. Figure 1 Move in the direction of arrow A. The same applies to Figures 6 to 10 That is, the magnet 120 may be used instead of the plate-shaped first magnet 9 according to the above-mentioned embodiments and modifications, and even in this case, the same operations and effects as those of the above-mentioned embodiments and modifications can be achieved.

[0088] Next, other embodiments using the magnet 120 will be described in sequence. Figure 12 : is a diagram schematically showing a thrust generating mechanism 100 according to the third embodiment. Figure 12 As shown, the thrust generating mechanism 100 comprises: a magnet 120, a magnet 120 perpendicular to the moving direction indicated by the arrow A ( Figure 11 (a)) and the movable portion 3, the plate-shaped second magnet (fixed side magnet) 15 and the plate-shaped third magnet (fixed side magnet) 17 are respectively arranged on both sides of the magnet 120. It should be noted that the magnet 120 may not be perpendicular to the moving direction shown by the arrow A (in other words, the two end surfaces of the disk-shaped magnet 110 are not facing the direction perpendicular to the moving direction). For example, it can be installed as Figure 12 In (a), the leftward or rightward tilt (in other words, the direction in which the end surfaces of the disk-shaped magnet 110 are perpendicular to the direction of movement) is sufficient. In short, the arrangement direction of the magnet 120 can be any direction other than the direction of movement indicated by the arrow A (in other words, a direction intersecting the direction of movement and with the end surfaces of the disk-shaped magnet 110 facing in a direction different from the direction of movement), and can be appropriately changed according to the specifications.

[0089] The moving part 3 has a plate-shaped base member 11A made of a magnetic body such as iron and four wheels 13 (see FIG. 1 ) provided on the front and rear of the lower part of both sides of the base member 11A and placed on a plane G. Figure 12(b)), and can be moved in the forward direction indicated by arrow A ( Figure 12 The magnet 120 is attached to the base member 11A by magnetic bonding. It should be noted that the base member 11A may also be made of a non-magnetic material such as resin, similar to the housing 11. In this case, the magnet 120 may be fixed to the base member 11A by adhesive bonding, welding, screws, or other fixing means.

[0090] like Figure 12 As shown in (a), the second plate-shaped magnet 15 and the third plate-shaped magnet 17 are both fixed in a flat position at a certain distance from both sides of the magnet 120. Figure 12 The plate-shaped second magnet 15 in (a) has an S-pole on the lower left side 15a and is parallel to the plane G. Figure 12 The plate-shaped second magnet 15 in (a) has a north pole on its upper right side 15b and is parallel to plane G. Similarly, the left side 17a and right side 17b of the plate-shaped third magnet 17 have south and north poles, respectively, and are parallel to plane G. The boundary line of these plate-shaped second magnet 15 and plate-shaped third magnet 17 coincides with boundary line MC of magnet 120.

[0091] As a result, the N-pole portion ( Figure 12 (a) as the upper half of the plate-shaped second magnet 15 and the plate-shaped third magnet 17) and the region R1 as the N-pole portion of the outer peripheral surface of the magnet body 120 (refer to Figure 11 (b)) are facing each other. Similarly, the S pole portion of the outer peripheral surface of the plate-shaped second magnet 15 and the plate-shaped third magnet 17 ( Figure 12 (a) is the black portion of the lower half of the plate-shaped second magnet 17) and the region R2 (refer to FIG. 1 ) is the S pole portion of the outer peripheral surface of the magnet body 120. Figure 11 (b) facing each other.

[0092] like Figure 12As shown in FIG. 2( b ), the plate-shaped second magnet 15 is fixed so as to be inclined toward the upper left of the top view relative to the direction of movement of the moving portion 3 indicated by arrow A (hereinafter sometimes referred to as the "movement direction"). In other words, the plate-shaped second magnet 15 is fixed so that the distance between the plate-shaped second magnet 15 and the magnet 120 increases as the plate-shaped second magnet 15 moves in the movement direction indicated by arrow A. Thus, the distance between the plate-shaped second magnet 15 and the magnet 120 is designed to increase as the plate-shaped second magnet 15 approaches the downstream side of the movement direction indicated by arrow A (hereinafter sometimes referred to as the "downstream side"), and the distance between the downstream side of the plate-shaped second magnet 15 and the magnet 120 is designed to be greater than the distance between the upstream side of the plate-shaped second magnet 15 in the movement direction indicated by arrow A (hereinafter sometimes referred to as the "upstream side") and the magnet 120.

[0093] Similarly, the planar third magnet 17 is fixed so that it is tilted toward the upper right in the top view relative to the direction of movement. In other words, the planar third magnet 17 is fixed so that the distance between the planar third magnet 17 and the magnet 120 increases as the planar third magnet 17 moves downstream. Thus, the distance between the planar third magnet 17 and the magnet 120 is designed to increase as it approaches the downstream side, and the distance between the downstream portion of the planar third magnet 17 and the magnet 120 is designed to be greater than the distance between the upstream portion of the planar third magnet 17 and the magnet 120.

[0094] That is, the plate-shaped second magnet 15 and the plate-shaped third magnet 17 are arranged in a twisted position that is tilted relative to the magnet 120 in a top view, and the magnet 120 is vertical and upright relative to the moving direction of the moving part 3. With such a structure, the moving part 3 moves in the moving direction indicated by the arrow A due to the repulsive force generated between the plate-shaped second magnet 15 and the magnet 120 and the repulsive force generated between the plate-shaped third magnet 17 and the magnet 120. It should be noted that although Figure 12 The left magnet 15 and the right magnet 17 are configured in the figure, but it can also be changed, such as configuring only the plate-shaped second magnet 15, or configuring only the plate-shaped third magnet 17, and even in this case, the moving part 3 moves along the moving direction shown by the arrow A.

[0095] Figure 13 Schematically shows a thrust generating device 100 according to a fourth embodiment. Figure 13 As shown in FIG. 2( a ), the second plate-shaped magnet 15 in a flat state is located in the region R1 (refer to FIG. 2 ) of the outer peripheral surface of the magnet 120. Figure 11 (b)) and is located above the boundary line MC (hereinafter sometimes referred to as "above the boundary line MC"). The plate-shaped second magnet 15 is Figure 13(a) is a front view) and is tilted to the upper left relative to the boundary line MC. In other words, the plate-shaped second magnet 15 is tilted so that the closer it is to the downstream side, the greater the distance from the boundary line MC. Figure 13 As shown in (b), the plate-shaped second magnet 15 is arranged parallel to the moving direction.

[0096] That is, the plate-shaped second magnet 15 is arranged in a twisted position tilted relative to the magnet 120 in the side view, and the magnet 120 is vertical and upright relative to the moving direction. Even with such a structure, the moving part 3 moves in the moving direction indicated by the arrow A. Although in this Figure 13 The figure shows a state where only the plate-shaped second magnet 15 is arranged above the boundary line MC. Figure 14 As shown, the flat plate-shaped third magnet 17 can also be arranged in the region R2 (refer to Figure 11 (b)) and is located below the boundary line MC (hereinafter, sometimes simply referred to as "below the boundary line MC").

[0097] like Figure 14 As shown in (a), in the side view, the plate-shaped third magnet 17 is tilted to the lower left relative to the boundary line MC. In other words, the plate-shaped third magnet 17 is tilted so that the closer it is to the downstream side, the greater the distance from the boundary line MC. Figure 14 As shown in (b), the plate-shaped third magnet 17 is arranged parallel to the moving direction of the moving part 3. That is, Figure 14 The plate-shaped third magnet 17 is arranged in a twisted position tilted relative to the magnet 120 in a side view, and the magnet 120 is vertical and upright relative to the moving direction. Even with such a structure, the moving part 3 moves in the moving direction indicated by the arrow A.

[0098] It should be noted that although Figure 13 and 14 The example shows a state in which the plate-shaped second magnet 15 or the plate-shaped third magnet 17 is provided only on one of the two sides of the magnet 120 and above or below the boundary line MC, but the plate-shaped second magnet 15 and the plate-shaped third magnet 17 may be respectively arranged above the boundary line MC of the magnet 120 and on both sides of the magnet 120. In addition, the plate-shaped second magnet 15 and the plate-shaped third magnet 17 may be respectively arranged below the boundary line MC of the magnet 120 and on both sides of the magnet 120. In short, the plate-shaped second magnet 15 or the plate-shaped third magnet 17 may be provided on at least one of the two sides of the magnet 120 and at least one of the positions above and below the boundary line MC. In addition, the plurality of plate-shaped second magnets 15 and the plate-shaped third magnets 17 may be arranged in a plurality of rows along the moving direction (for example, refer to Figure 4 and Figure 7 In either case, the moving portion 3 moves in the direction indicated by the arrow A.

[0099] In addition, although Figure 13 and Figure 14 The plate-shaped second magnet 15 (plate-shaped third magnet 17) is used, but it can also be changed, such as Figure 15 As shown in (a) and (b), a conical magnet 130 can be used, the diameter (thickness) of which gradually increases as it moves in the direction indicated by the arrow A. Figure 9 As described in (b), the magnetic force at the downstream end of the conical magnet 130 is designed to be stronger than the magnetic force at the upstream end. Figure 15 (a) is a top view of the conical magnet 130, and (b) is a side view. The conical magnet 130 is in a flat state, for example, Figure 15 As shown in (c) and (d), the plurality of conical magnets 130 are arranged on one side of the magnet 120 and above the boundary line MC along the moving direction indicated by arrow A. Even with such a structure, the moving part 3 moves in the moving direction indicated by arrow A.

[0100] It should be noted that if Figure 15 As shown in (e), the plurality of conical magnets 130 may also be arranged in a position below the boundary line MC on one side of the magnet 120 along the moving direction indicated by the arrow A. Figure 16 As shown, the conical magnet 130 may be arranged both above and below the boundary line MC of the magnet 120. In short, the conical magnet 130 may be provided on at least one of the two sides of the magnet 120, at least one of above and below the boundary line MC. In either case, the moving portion 3 moves in the direction indicated by the arrow A.

[0101] like Figure 17 As shown in Figure 12 (b) The same as the plate-shaped second magnet 15 and the plate-shaped third magnet 17 described above, the conical magnet 130 can also be configured to be inclined relative to the moving direction indicated by the arrow A in the top view (configured to be in a twisted position relative to the magnet 120). Even with such a structure, the moving part 3 moves along the moving direction indicated by the arrow A. It should be noted that in Figure 17 In the embodiment, the plurality of conical magnets 130 are arranged on both sides of the magnet 120 along the moving direction indicated by the arrow A.

[0102] Although in the above Figures 11 to 17In the embodiment shown, the fixed side magnets (including the plate-shaped second magnet, the plate-shaped third magnet, and the conical magnet) are all in a flat position relative to the moving side magnet (composed of a plurality of disc-shaped magnets stacked and extending in a rod-shaped manner). However, as mentioned above, the fixed side magnets arranged on both sides of the magnets may also be in an upright position. Specifically, Figure 18 and Figure 19 shown.

[0103] like Figure 18 As shown in (a), a plate-shaped second magnet 15 and a plate-shaped third magnet 17 are arranged in an upright state on both sides of the magnet 120 and above and below the boundary line MC. Of the upper and lower plate-shaped second magnets 15, the surface of the upper plate-shaped second magnet 15 having the north pole ( Figure 18 (a) right side) 15b and the upper half region R1 of the outer peripheral surface of the magnet 120 having the N pole magnetic pole (reference Figure 11 (b)) are facing each other. In addition, among the upper and lower plate-shaped second magnets 15, the surface of the other side of the lower plate-shaped second magnet 15 having the S pole ( Figure 18 (a) right side) 15a and the lower half region R2 (reference) of the outer peripheral surface of the magnet 120 having the S pole Figure 11 (b)) are facing each other. Similarly, in the plate-shaped third magnet 17, the surface of the upper plate-shaped third magnet 17 having the N-pole polarity (at Figure 18 (a) is the left side) 17b faces the upper half area R1 of the outer peripheral surface of the magnet 120, and the other side surface of the plate-shaped third magnet 17 with the S pole (at Figure 18 (a) is the left side) 17a faces the lower half area R2 of the outer peripheral surface of the magnet 120. Figure 18 As shown in (b), the second plate-shaped magnet 15 (the third plate-shaped magnet 17) is tilted relative to the boundary line MC in a side view (formed in a twisted positional relationship relative to the magnet 120). Even with such a structure, the moving part 3 ( Figure 18 (not shown in the figure) also moves in the direction of movement indicated by arrow A.

[0104] like Figure 19 As shown in (a), the plate-shaped second magnet 15 (plate-shaped third magnet 17) can be arranged to be parallel to the boundary line MC in a side view, and as shown in FIG. Figure 19 As shown in (b), the plate-shaped second magnet 15 is tilted relative to the boundary line MC in a top view (the positional relationship relative to the magnet 120 is twisted). Even with such a structure, the moving part 3 ( Figure 19 (not shown in the figure) also moves in the direction of movement indicated by arrow A.

[0105] It should be noted that, although the plate-shaped second magnet 15 and the plate-shaped third magnet 17 are used as the fixed side magnets, Figure 20 As shown, a fixed side magnet 135 formed by laminating the plate-shaped second magnets 15 (plate-shaped third magnets 17) may be used, and even in this case, the moving part 3 ( Figure 20 (not shown in the figure) also moves in the direction of movement indicated by arrow A.

[0106] Here, yes Figures 12 to 14 、 Figure 18 and Figure 19 The positional relationship between the magnet 120 and the plate-shaped second magnet 15 and the plate-shaped third magnet 17 can be summarized as follows (1) to (4). In the following description, for simplicity, the plate-shaped second magnet 15 is represented as "left" and the plate-shaped third magnet 17 is represented as "right". (1) Both sides are in a flat position, and both sides are tilted in the top view (refer to Figure 12 ). (2) Both sides are in a flat position, and both sides are tilted in the side view (refer to Figure 13 ). (3) Both sides are upright, and both sides are tilted in the top view (refer to Figure 19 ). (4) Both sides are upright, and both sides are tilted in the side view (refer to Figure 18 ).

[0107] In addition, the positional relationship between the magnet 120 and the plate-shaped second magnet 15 and the plate-shaped third magnet 17 can be not only the above (1) to (4), but also the following (5) to (9). The key is that as long as the plate-shaped second magnet 15 and the plate-shaped third magnet 17 are formed in a positional relationship that is twisted relative to the magnet body 120, the same applies to this positional relationship. Figures 15 to 17 The conical magnet 130 is shown. (5) Either one of the left and right parts is in a horizontal position, while the other is in an upright position, and both are tilted in the top view. (6) Either one of the left and right parts is in a horizontal position, while the other is in an upright position, and both are tilted in the side view. (7) Either one of the left and right sides is in a horizontal position, while the other is in an upright position; either one of the left and right sides is tilted in a top view, while the other is tilted in a side view. (8) In either of the above-mentioned flat positions, in the rear view (front view), at least one of the left and right sides is slightly tilted in the direction intersecting with the boundary line MC (for example, Figure 12 (a) The state where the plate-shaped second magnet 15 is inclined with respect to the boundary line MC, etc.) (9) In either of the above-mentioned upright positions, in the rear view (front view), at least one of the left and right sides is slightly inclined in the direction intersecting with the boundary line MC (for example, Figure 18 The plate-shaped second magnet 15 shown in (a) is located relative to the central axis of the magnet 120 (not shown). Figure 18 (a) is in a tilted state in the vertical direction perpendicular to the boundary line MC).

[0108] In addition, in the above Figures 11 to 17 In the embodiment shown, a magnet 120 is used in which a plurality of disk-shaped magnets 110 as moving side magnets are stacked and extended in a rod shape, but a single moving side magnet may be used instead. Specifically, Figure 11 The disk-shaped magnet 110 shown in (b) can be a long and thin bar-shaped bar magnet (not shown) (having Figure 11 The rod-shaped magnet may be a single rod-shaped bar magnet in the shape of the magnet 120 shown in FIG. The rod-shaped magnet may extend perpendicularly to the direction of movement indicated by arrow A or in a direction intersecting the direction of movement. Alternatively, the magnet may be formed by assembling the above-described bar-shaped magnets into, for example, an E-shaped or square shape. In either case, the same functions and effects as those of the above-described embodiments and modifications can be achieved.

[0109] In each of the above-described embodiments and variations, the movement direction restricting portion restricts the movement direction of the movable portion 3 by means of the housing 11 and the wheels 13. However, the movement direction restricting portion is not limited to the housing 11 and the wheels 13. Although not shown in the figures, the movement direction restricting portion may also be configured as a rail portion including a groove formed in the plane G and a protrusion formed on the bottom surface of the plate-shaped first magnet 9 into which the grooved rail portion is inserted; or a groove capable of inserting the bottom of the housing 11 of the movable portion 3 into the plane G may be used as the movement direction restricting portion. Various configurations may be employed, such as the above-described embodiment. Furthermore, the movement direction restricting portion may be configured to restrict movement not only in the front-to-back direction but also in the forward direction only. In short, any configuration may be employed as long as the movement direction of the movable portion 3, which is moved by the magnetic force (repulsive force) from the linear first magnet portion 5 and the linear second magnet portion 7, can be restricted. Figure 21 A specific example of the moving portion 3 including the moving direction regulating portion is shown.

[0110] like Figure 21As shown in (a), the moving part 3 includes: a track body 140 placed on the plane G and extending along the moving direction of the moving part 3, and a moving body 150 that moves (slides) along the track body 140. The track body 140 is composed of a plate-shaped first plate-shaped portion 141 placed on the plane G (including the case where it is installed on the floor or the wall of a structure, etc.), a plate-shaped second plate-shaped portion 142 parallel to the first plate-shaped portion 141, and a connecting portion 143 connecting the plate-shaped portions 141 and 142, and is formed into a roughly H shape. The moving body 150 includes: a plate-shaped placement portion 151 on which the magnet 120 is installed; first limiting portions 152, 152 extending from both ends of the placement portion 151 toward the plane G and limiting the left and right movement of the moving body 150 (as shown in FIG. Figure 21 (a)); the second limiting portion 153, 153, extends from the inner side of the first limiting portion 152, 152 toward the connecting portion 143 and limits the upward movement of the moving body 150 (as shown in FIG. Figure 21 (a) shown); and wheels 13, 13, respectively mounted on the second limiting portion 153, 153. By such a structure, the moving portion 3 Figure 21 The left, right, up, and down movements in (a) are restricted, and the movement direction is limited to either forward or backward.

[0111] Although Figure 21 In (a), the moving part 3 is mounted on the other end of the magnet 120, but as Figure 21 As shown in (b), the moving parts 3, 3 can be respectively installed at the two ends of the magnet 120. Figure 21 , the magnet 120 is mounted along Figure 2 The vertical direction of the extension, but not limited to this, for example, can also be as follows Figure 22 As shown, the magnet 120 is mounted along Figure 22 The arrangement direction is not particularly limited.

[0112] Figure 23 It is a diagram schematically showing a perspective state of a thrust generating device according to a fifth embodiment. Figure 24 This is a side view showing an enlarged view of a swing mechanism of a thrust generating device according to a fifth embodiment. Figures 25 to 28 It is a diagram schematically showing the operation flow of the displacement mechanism in the thrust generating device according to the fifth embodiment.

[0113] like Figure 23 and Figure 24As shown, the thrust generating device 200 according to the fifth embodiment includes: a rotating body 210, which is supported by a rotating shaft 202, and the rotating shaft 202 is fixed in an upright state (vertical direction) to a base 201 placed on a placement surface; three rotating side magnets 221, 222, and 223, which are fixed to the rotating body 210 and extend in the same direction and parallel to the rotating shaft 202; three swing mechanisms (displacement mechanisms) 231, 232, and 233 ( Figure 23 The diagram is omitted, please refer to Figure 27 (a) schematically shown), arranged around rotating body 210; and three fixed-side magnets 241, etc., which are swung by swing mechanisms 231, 232, and 233. It should be noted that only fixed-side magnet 241 is shown as a fixed-side magnet, and the illustration and reference numerals of the other two fixed-side magnets are omitted. Herein, the three rotating-side magnets 221, 222, and 223 are sometimes collectively referred to as rotating-side magnets 221, etc. Furthermore, as described above, the three fixed-side magnets are collectively referred to as fixed-side magnets 241, etc.

[0114] like Figure 25 As shown, the rotating side magnets 221 and the like are each formed to be Figure 11 (a) has the same structure as the magnet 120 shown, and as Figure 11 As shown in (b), the peripheral surface (end surface) above the boundary line MC has the polarity of the N pole, and the peripheral surface (end surface) below the boundary line MC has the polarity of the S pole. Figure 23 Of course, it is also possible not to use the rotating side magnet 221. Figure 11 (b) shows the magnet 120, but uses a single elongated rod-shaped magnet.

[0115] like Figure 26 As shown, the fixed-side magnet 241 and the like are formed into a tapered shape, the diameter (thickness) of which gradually increases as it approaches the rotational direction of the rotating body 210 indicated by the arrow G. By forming the fixed-side magnet 241 into such a tapered shape, as described in 9(b) above, the magnetic force at the downstream end of the fixed-side magnet 241 is stronger than the magnetic force at the upstream end.

[0116] The rotating body 210 has a disk-shaped upper support portion 211 and a lower support portion 212 made of resin or the like, and three magnet fixing portions 213 provided to hang down from the lower surface of the upper support portion 211 (see FIG. Figure 25 (a)). It should be noted that, as the magnet fixing portion, only the magnet fixing portion 213 is shown in the figure, and the illustration and reference numerals of the other two magnet fixing portions are omitted. Here, as described above, the three magnet fixing portions are collectively referred to as the magnet fixing portion 213, etc.

[0117] The center portions of the upper support portion 211 and the lower support portion 212 are rotatably supported by the rotating shaft 202. The magnet fixing portion 213 and the like are arranged along the rotation direction of the upper support portion 211 (refer to FIG. Figure 27 The arrow G shown in (a) is in the counterclockwise direction in the top view) and is equally spaced from each other. In other words, when viewed from the center (axial core) of the upper support portion 211, the positional relationship of the magnet fixing portion 213, etc. is at an angle of 120 degrees to each other. Each of the magnet fixing portion 213, etc. is fixed with a rotating side magnet 221, etc. Thus, as shown in FIG. Figure 27 As shown in (a), the rotating side magnets 221 and the like are also located along the rotation direction of the upper support portion 211 and are equally spaced from each other (at an angle of 120 degrees to each other).

[0118] like Figure 23 、 Figure 25 as well as Figure 26 As shown, on the lower surface of the outer peripheral edge of the upper support portion 211, at positions corresponding to the rotating side magnets 221 and the like, convex portions 214, 215, and 216 (hereinafter, these convex portions 214, 215, and 216 are sometimes collectively referred to as convex portions 214, etc.) are respectively provided. Furthermore, on the upper surface of the outer peripheral edge of the lower support portion 212, convex portions 217, 218, and 219 (hereinafter, these convex portions 217, 218, and 219 are sometimes collectively referred to as convex portions 217, etc.) are also provided, directly below each convex portion 214, etc., and are formed into a semi-elliptical shape that protrudes upward in a side view.

[0119] like Figure 27 As shown, the swing mechanism 231 and the like are arranged on the circumferential outer side of the rotating body 210 and close to the position of the rotating body 210. The swing mechanisms 231 and the like are arranged to be equally spaced from each other along the rotation direction of the rotating body 210. In other words, when viewed from the center (axial core) of the rotating body 210, the swing mechanisms 231 and the like are also arranged to form an angle of 120 degrees with each other. In addition, the swing mechanism 231 and the like are constructed separately from the rotating body 210 and their configuration positions can be adjusted, but the swing mechanism 231 and the like and the rotating body 210 can also be set as an integrated structure. It should be noted that since each of the swing mechanisms 231 and the like is formed into the same structure, only the swing mechanism 231 will be described, and the description of the other swing mechanisms 232 and 233 will be omitted.

[0120] like Figure 24As shown, the swing mechanism 231 has: a support column portion 252, which is fixed to a base portion 251 placed on a placement surface in an upright state (vertical direction); an upper support portion 253, which extends horizontally from the upper end of the support column portion 252 to the rotating shaft 202; a first swing shaft portion 254, which is provided at the front end portion of the upper support portion 253 and is fixed with a fixed side magnet 241; and a linkage portion 255, which swings (rotates) the fixed side magnet 241 by linkage with the rotation of the rotating body 210. The linkage portion 255 has: a holding portion 256 with a bottom box shape; a second swing shaft portion 257, which is provided on the upper end surface of the fixed side magnet 241 and is fixed with the holding portion 256; a rotating shaft 258, which is provided horizontally (in Figure 24 The side of the holding portion 256 is penetrated (in the left and right directions) Figure 24 and a disc-shaped rotating plate 259, which is rotatably supported on the rotating shaft 258.

[0121] In the fifth embodiment, similar to the above embodiment, the fixed side magnet 241 is set to be in a twisted position relative to the rotating side magnet 221. Specifically, it is set as follows: Figure 25 (a) and Figure 26 As shown in (a), the fixed side magnet 241 is tilted so that its upper end is closer to the rotating side magnet 221 than its lower end. Figure 25 (a) is tilted to the upper left), and the fixed side magnet 241 is fixed with its downstream side end (at Figure 26 (a) is the right end) is located higher than its upstream end (at Figure 26 (a) is the left end) and is tilted (at Figure 26 (a) is tilted to the upper right). In addition, Figure 25 As shown in (a), the upper end of the fixed side magnet 241 ( Figure 26 (The upper right end shown in (a)) is arranged at a position below the line segment HC which is horizontal to the upper surface of the rotating side magnet 221, etc., and in this embodiment, the fixed side magnet 241, etc. is located between the center line MC and the line segment HC, and the upper end of the fixed side magnet 241 is in contact with the line segment HC.

[0122] The first swing shaft 254 is a component that causes the fixed side magnet 241 fixed to the first swing shaft 254 to swing up and down. In addition, the first swing shaft 254 is always urged by a spring (not shown) so that the fixed side magnet 241 faces upward. As a result, when the rotating side magnet 221 and the like are separated from the fixed side magnet 241 (for example, Figure 26 (a) and Figure 27 (a) shows a state where the fixed side magnet 241 is located between the rotating side magnets 221 and 222, and the rotating plate 259 is in contact with the lower surface of the upper support portion 211. In other words, this position ( Figure 25 The position shown in (a) can also be called the initial position of the fixed side magnet 241. In addition, in this state, the fixed side magnet 241 is Figure 25 (a) is in an upright position tilted to the upper left, and Figure 28 (a) shows the end face with S polarity (at Figure 25 (a) is the left end surface) becomes the peripheral surface with N-pole polarity facing the rotating side magnet 221. In this case, Figure 28 As shown in (a), the attractive force between different magnetic poles between the fixed-side magnet 241 and the rotating-side magnet 221 becomes stronger.

[0123] In this state, when the rotating plate 259 abuts against the protrusion 214, as shown in FIG. Figure 25 (b) As shown in FIG26(b), the rotating plate 259 is pushed downward by the protrusion 214. When the holding portion 256 is pushed downward, the fixed side magnet 241 overcomes the force of the spring and moves toward the first swing shaft portion 254. Figure 25 (b) is rotated to the lower left. In other words, the position ( Figure 25 The position shown in (b) can also be called the middle position of the fixed side magnet 241. In addition, in this state, Figure 26 (b) Figure 27 As shown in (b), the fixed side magnet 241 and the rotating side magnet 221 are adjacent to each other, and the fixed side magnet 241 gradually tilts downward to the left. Figure 25 As shown in (b), the end surface of the fixed side magnet 241 having the N-pole polarity (at Figure 25 (a) is the right end surface) gradually toward the peripheral surface with N-pole polarity of the rotating side magnet 221, etc. In this case, as Figure 28 As shown in (b), between the fixed-side magnet 241 and the rotating-side magnet 221, etc., the attractive force between different poles and the repulsive force between the same poles act approximately equally.

[0124] Then, when the rotating plate 259 hits the apex of the convex portion 214, as shown in FIG. Figure 25 (c) As shown in FIG26(c), the rotating plate 259 is further pushed downward by the protrusion 214, and the fixed side magnet 241 is further tilted downward. In other words, this position ( Figure 25 The position shown in (c) can also be called the final position of the fixed side magnet 241. As a result, the end surface of the fixed side magnet 241 with N-pole polarity further faces the peripheral surface of the rotating side magnet 221 with N-pole polarity. In this case, Figure 28 As shown in (c), a repulsive force between the same poles strongly acts between the fixed-side magnet 241 and the rotating-side magnet 221 and the like.

[0125] Next, based on the above structure, the operation of the thrust generating device of the fifth embodiment will be described. Figure 25 As shown in (a), 26 (a), and 27 (a), the fixed side magnet 241 is located between the rotating side magnets 221 and 222 (at Figure 26 (a) shows a state where the rotating side magnet 221 reaches the upstream end of the fixed side magnet 241. When the rotating side magnet 221 is separated from the fixed side magnet 241, Figure 28 As shown in (a), the end surface of the fixed side magnet 241 with the south pole polarity is turned toward the peripheral surface of the rotating side magnet 221 with the north pole polarity (the peripheral surface of the upper half of the rotating side magnet 221), and between the fixed side magnet 241 and the rotating side magnet 221, as shown in FIG. Figure 28 As shown in (a), the attractive force between the opposite poles (in this case, the attractive force between the south pole of the fixed-side magnet 241 and the north pole of the rotating-side magnet 221) is strong. Therefore, due to the attractive force between the fixed-side magnet 241 and the rotating-side magnet 221, the rotating-side magnet 221 is attracted to the fixed-side magnet 241, and a rotational force in the direction indicated by arrow G is applied to the rotating body 210, causing the rotating body 210 to rotate. Furthermore, in this state, the rotating plate 259 of the swing mechanism 231 rotates while in contact with the lower surface of the upper support portion 211 of the rotating body 210.

[0126] Afterwards, if Figure 25 As shown in (b), 26 (b), and 27 (b), when the fixed side magnet 241 is in the middle position (the rotating side magnet 221 reaches a position facing the substantially central portion of the fixed side magnet 241), Figure 28 As shown in (b), the attractive force between opposite poles and the repulsive force between like poles act between the fixed-side magnet 241 and the rotating-side magnet 221, and the influence on the rotating body 210 is reduced. Therefore, since the rotating body 210 is difficult to brake during rotation (because the rotational potential energy of the rotating body 210 is large), the rotating body 210 continues to rotate.

[0127] Afterwards, if Figure 25 As shown in (c), 26 (c), and 27 (c), when the fixed side magnet 241 is in the final position (the position where the rotating side magnet 221 reaches the downstream end of the fixed side magnet 241), between the fixed side magnet 241 and the rotating side magnet 221, as shown in Figure 28 As shown in (c), the repulsive force between the same poles is strong. Therefore, due to the repulsive force between the fixed-side magnet 241 and the rotating-side magnet 221, the rotating-side magnet 221 and the fixed-side magnet 241 repel each other, and a rotational force in the direction of rotation indicated by arrow G is applied to the rotating body 210, causing the rotating body 210 to rotate.

[0128] As the rotating body 210 rotates, the fixed-side magnet 241 is positioned between the rotating-side magnets 221 and 223. The same process is then repeated, causing the rotating body 210 to rotate continuously. This process also applies to positions between fixed-side magnets other than the fixed-side magnet 241 and the rotating-side magnet 221.

[0129] As described above, by swinging the fixed-side magnets 241 and other components of the swing mechanism 231 relative to the rotating-side magnets 221 and other components fixed to the rotating body 210, the attractive force between opposite poles and the repulsive force between like poles are switched, allowing the rotating body 210 to rotate smoothly. Furthermore, by providing a freely rotatable rotating plate 259 as a component in contact with the upper support portion 211 in the swing mechanism 231 and other components, the resistance to the rotating body 210 during rotation can be reduced, and the rotation of the rotating body 210 can be prevented from being disturbed. Therefore, a material such as a resin or metal with a low coefficient of friction is preferably used for the rotating plate 259. Furthermore, since the fixed-side magnets 241 are formed into a tapered shape with increasing thickness toward the downstream side, the repulsive force between the fixed-side magnets 241 and the rotating-side magnets 221 and other components can be strengthened when the fixed-side magnets 241 are in their final position, thereby further applying the rotational force of the rotating body 210.

[0130] In this embodiment, the fixed side magnet 241 is provided between the center line MC and the line segment HC and the upper end of the fixed side magnet 241 is in contact with the line segment HC. However, as for the position of the fixed side magnet 241, for example, Figure 29 As shown in (a) to (c), it can also be set to be located approximately in the center of the center line MC and the line segment HC. Figure 30 As shown in (a) to 30 (c), the fixed side magnet 241 may be provided between the center line MC and the line segment LC which is horizontal to the lower surface of the rotating side magnet 221. Figure 30 In the examples shown in (a) to 30(c), the fixed side magnet 221 is arranged at a position where the lower end of the fixed side magnet 221 contacts the line segment LC. In this case, since the polarity of the lower half of the circumference of the rotating side magnet 221 is the S pole (refer to Figure 11 (b)), so that in the initial position, the fixed side magnet 241 is fixed to the first swing shaft portion in such a manner that the end face having the N-pole polarity faces the rotating side magnet 221 and the end face having the S-pole polarity faces the opposite side thereof. In addition, the rotating plate 259 of the swing mechanism 231 contacts the upper surface of the lower support portion 212 or the protrusion 217, etc. In short, the position of the fixed side magnet 241 can be any position within the range between the line segment HC and the line segment LC, and the same action and effect as described above can be achieved at any position. Of course, the position Figure 25 The fixed side magnet 241 at position (a) and the fixed side magnet 241 at position (b) Figure 30The fixed side magnet 241 at the position (a) may also be provided at the same time.

[0131] Although the fixed-side magnets 241 are disposed outside the rotating body 210 in this embodiment, the fixed-side magnets 241 may be disposed inside the rotating body 210, that is, between the rotating shaft 202 and the rotating-side magnets 221, etc. Alternatively, the fixed-side magnets 241 may be disposed both outside and inside the rotating body 210. Even in this case, the same operations and effects as those of the above-described embodiment can be achieved.

[0132] While three rotating-side magnets 221 are provided in this embodiment, the number of rotating-side magnets provided may be one or more than three. Furthermore, when multiple rotating-side magnets 221 are provided, they may not be evenly spaced but may be arranged irregularly. In short, the number of rotating-side magnets provided and the spacing between them can be appropriately set according to specifications. Even in this case, the same functions and effects as the above-described embodiment can be achieved.

[0133] Although in this embodiment, the swing mechanism 231 is provided to mechanically swing the fixed side magnet 241, for example, the fixed side magnet 241 may be electrically swung using a solenoid or the like, or the fixed side magnet 241 may be swung by a motor or the like. In addition, the fixed side magnet 241 may be rotated instead of being swung. Specifically, Figure 28 In the state (a), the end surface of the S pole of the fixed side magnet 241 is positioned to face the peripheral surface of the N pole of the rotating side magnet 221, and Figure 28 In the state (c), the fixed-side magnet 241 is rotated 180 degrees so that the end surface of the north pole of the fixed-side magnet 241 faces the peripheral surface of the north pole of the rotating-side magnet 221. In short, any method that can displace the position of the fixed-side magnet 241, whether mechanical or electrical, will suffice.

[0134] In this embodiment, as the rotating body 210, Figure 23 The structure shown in FIG. 1 is not limited thereto. For example, Figure 31 and Figure 32As shown, a rotating body 300 can also be used, which includes multiple support members 250 rotatably supported on a rotating shaft 202 and extending in radial directions. A rotating-side magnet 221 is fixed to the front end of each support member 250. Alternatively, a rotating-side magnet 221A (identical to rotating-side magnet 221, but with the letter "A" added to the end for easier identification) can be attached to the side of the support member 250. In this case, a fixed-side magnet is disposed on at least one of the upper and lower sides of the rotating-side magnet 221A. Even with this configuration, the same functions and effects as those of the above-described embodiment can be achieved.

[0135] In addition, if Figure 31 and 32 As shown, as the fixed side magnet, a plate-shaped fixed side magnet 260 may be used which is extended in a direction perpendicular to the rotation axis 202 and has a shape such that the downstream end portion in the rotation direction is bent at a predetermined angle (for example, 30 degrees) toward the rotating side magnet 221. In this case, for example, Figure 28 (c) The fixed side magnet 241 is replaced with the fixed side magnet 260. Figure 28 In (c), the right end of the fixed-side magnet 260 is bent toward the rotating-side magnet 221. This allows the north-pole end face of the fixed-side magnet 241 to be closer to the rotating-side magnet, and this end face and the north-pole circumference of the rotating-side magnet 221 to be more closely aligned. This strengthens the repulsive force between the rotating-side magnet 221 and the fixed-side magnet 241. It should be noted that the fixed-side magnet 260 can extend not only in a direction perpendicular to the rotating axis 202 but also in a direction oblique to the rotating axis 202. In short, any configuration is sufficient as long as the fixed-side magnet is arranged to extend in a direction intersecting the rotating axis 202 (in a twisted position relative to the rotating-side magnet).

[0136] Although Figure 31 and Figure 32 The fixed side magnet 260 is shown as an example, which is bent at an angle of 30 degrees to the plane, but it is also possible to use Figure 33 (a) shows a fixed side magnet 261 bent 90 degrees, Figure 33 (b) The fixed side magnet 262 bent 120 degrees or Figure 34 (a) is replaced by the fixed side magnet 263 bent at 45 degrees, and the bending angle can be appropriately set according to the specifications. In addition, the bending of the plate-shaped fixed side magnet can also be as shown in FIG. Figure 32 (b), 33 (a) and 33 (b) show that a portion of the plate-shaped fixed side magnet is bent, or it can also be as shown in Figure 34 (b) shows the left-right twisted shape of the fixed side magnet.

[0137] Next, based on Figure 35 to Figure 37-2 , the sixth embodiment will be described. In addition, in the description of the sixth embodiment, the difference between it and the fifth embodiment will be mainly described. The difference between the sixth embodiment and the fifth embodiment is mainly that, Figure 27 The swing mechanisms 231, 232, and 233 in the thrust generating mechanism shown in (a) are respectively used Figure 35 The up and down moving mechanism 310 shown is replaced.

[0138] like Figure 35 to Figure 37-2 As shown, the vertical movement mechanism 310 includes a plate-shaped magnet (fixed side magnet) 320 as a permanent magnet and a limiting portion 330 that limits the plate-shaped magnet 320 to move only in the vertical direction. The limiting portion 330 includes a housing portion 333 fixed to a support shaft 332, and the support shaft 332 is fixed in an upright state (vertical direction) to a base 331 placed on a flat surface (placement surface) G (reference Figure 37-1 (A)). Figure 35 As shown in (a), the storage unit 333 is made of a non-magnetic material such as resin and is formed into a box shape having a rectangular inner space NK. The plate-shaped magnet 320 is accommodated in the inner space NK and can freely move up and down therein (freely reciprocate up and down). Figure 35 As shown in FIG. 2 , a pair of vertically extending parallel rails RL are provided on the inner side surface of the rear wall of the storage portion 333. Furthermore, a spring SP is provided on the lower surface of the upper wall of the storage portion 333 to bias the plate-shaped magnet 320 in the storage portion 333 downward.

[0139] like Figure 35 As shown in (a), the front end surface of the plate-shaped magnet 320 (at Figure 35 (a) is the left end face, i.e. the other end face) 320a has the polarity of the S pole, and the rear end face of the plate-shaped magnet 320 (at Figure 35 (a) is the right end face, that is, one end face) 320b has the polarity of the N pole. When the base 331 is placed on the plane G, the two end faces 320a and 320b of the plate-shaped magnet 320 become vertical planes perpendicular to the plane G, and become parallel to and facing the rotating side magnet 221 and the like. Wheels SR1 are respectively provided above and below the two side faces of the plate-shaped magnet 320. In addition, wheels SR2 are also provided above and below the center part of the rear end face of the plate-shaped magnet 320. These wheels SR2 are interposed between a pair of rails RL and move along the pair of rails RL, thereby guiding the plate-shaped magnet 320 to move up and down. By providing these wheels SR1 and SR2, the plate-shaped magnet 320 can move up and down smoothly and reliably inside the storage portion 333.

[0140] like Figure 36As shown, the rotating side magnet 221 and the like are arranged along the axial direction of the rotating shaft 202 as described above, and the peripheral surface (one end surface) above the boundary line MC has the polarity of the N pole, and the peripheral surface (the other end surface) below the boundary line MC has the polarity of the S pole (also refer to Figure 11 (b)). In the state where the rotating side magnet 221 and the plate-shaped magnet 320 face each other ( Figure 37-1 (c)), the plate-shaped magnet 320 accommodated in the accommodation portion 333 reciprocates up and down between a first position and a second position, wherein the first position is a position where the other end face (S pole) of the rotating side magnet 221 and the front end face (the other end face of the S pole) 320a of the plate-shaped magnet 320 face each other (refer to Figure 36 (a)), the second position is the position where one end face (N pole) of the rotating side magnet 221 and the front end face (the other end face of the S pole) 320a of the plate-shaped magnet 320 face each other (reference Figure 36 (c)). In the first position, repulsion occurs between the rotating-side magnet 221 and the plate-shaped magnet 320 due to their like polarity. In the second position, attraction occurs between the rotating-side magnet 221 and the plate-shaped magnet 320 due to their different polarity. It should be noted that in the first position, the plate-shaped magnet 320 can be located anywhere between the center line MC and the line segment HC. In the second position, the plate-shaped magnet 320 can be located anywhere between the center line MC and the line segment LC.

[0141] Next, based on the above structure, the function of the thrust generating device of the sixth embodiment will be described. Figure 37-1 As shown in (a), the rotating side magnet 221 is located upstream of the plate-shaped magnet 320 in the direction of rotation, and the rotating side magnet 221 and the plate-shaped magnet 320 are separated (in other words, the plate-shaped magnet 320 is located between the rotating side magnets 221 and 222, also known as Figure 27 (a) The fixed side magnet 241 is replaced by the plate-shaped magnet 320. Figure 37-1 and Figure 37-2 (The rotating side magnet 222 is omitted in the figure) Figure 37-1 As shown in (A), the plate-shaped magnet 320 is located at the first position due to its own weight. Figure 36 As shown in (a), the rotating magnet 221 is attracted to the plate-shaped magnet 320 by the attractive force acting between one end surface (N pole) of the rotating magnet 221 and the front end surface (S pole) of the plate-shaped magnet 320, so that the rotating body 210 rotates.

[0142] Due to the magnetic force between the rotating side magnet 221 and the plate magnet 320, the rotating body 210 rotates (the rotating body 210 continues to rotate), and as shown in FIG. Figure 37-1As shown in (b), when the rotating side magnet 221 and the plate-shaped magnet 320 are close to each other, Figure 36 As shown in (b) and 37-1(B), the plate-shaped magnet 320 moves upward due to the repulsive force between the front end face (S pole) of the plate-shaped magnet 320 located at the first position and the other end face (S pole) of the rotating side magnet 221, and the attractive force between the front end face (S pole) of the plate-shaped magnet 320 and one end face (N pole) of the rotating side magnet 221. It should be noted that Figure 36 (b) and 37 - 1 (B) show a state in which the center of the plate-shaped magnet 320 in the first position in the vertical direction moves to the center position that coincides with the center line MC.

[0143] Thereafter, due to the magnetic force between the rotating side magnet 221 and the plate magnet 320, the rotating body 210 further rotates (the rotating body 210 continues to rotate), as shown in FIG. Figure 37-1 As shown in (c), in the position where the rotating side magnet 221 and the plate-shaped magnet 320 face each other, in other words, the rotating side magnet 221 and the plate-shaped magnet 320 are closest to each other and the attraction between them is the greatest, as shown in FIG. Figure 36 (c) and Figure 37-1 As shown in (C), the plate-shaped magnet 320 overcomes the biasing force of the spring SP in the storage portion 333 by the attractive force between the plate-shaped magnet 320 and the rotating-side magnet 221 and moves further upward to reach the second position.

[0144] Thereafter, the rotating body 210 further rotates due to its rotational potential energy (the rotating body 210 continues to rotate), as shown in FIG. Figure 37-2 As shown in (d), the rotating side magnet 221 moves to the downstream side of the rotating direction relative to the plate-shaped magnet 320, so that the rotating side magnet 221 is close to the plate-shaped magnet 320 (in other words, the plate-shaped magnet 320 is located between the rotating side magnets 221 and 223). Figure 37-1 and Figure 37-2 The illustration of the rotating side magnet 223 is omitted. ) Since the attraction between the magnets 221 and 320 is weaker than Figure 37-1 (c) shows the position where the rotating side magnet 221 and the plate magnet 320 face each other. Figure 37-2 As shown in (D), the plate-shaped magnet 320 moves downward due to the biasing force of the spring SP and its own weight.

[0145] Thereafter, the rotating body 210 further rotates (the rotating body 210 continues to rotate), as shown in FIG. Figure 37-2As shown in (e), the rotating side magnet 221 moves further downstream in the rotation direction relative to the plate-shaped magnet 320, so that the magnetic force between the rotating side magnet 221 and the plate-shaped magnet 320 is further weakened when the rotating side magnet 221 is separated from the plate-shaped magnet 320. Figure 36 As shown in (a) and 37-2(E), the plate-shaped magnet 320 is in the first position. Thereafter, the rotating body 210 rotates continuously by repeating the same action (in other words, the same action is repeated in the relationship between the rotating side magnets 222, 223 and the plate-shaped magnet 320).

[0146] As described above, in the sixth embodiment, the rotating body 210 is rotated by being attracted by the magnetic force between the rotating side magnet 221 etc. and the plate-shaped magnet 320. At the same time, the plate-shaped magnet 320 moves up and down due to the magnetic force between the rotating side magnet 221 etc. and the plate-shaped magnet 320. Through this interaction between the rotating side magnet 221 etc. and the plate-shaped magnet 320, the rotating side magnet can be rotated smoothly.

[0147] Although the fixed-side magnets 241 are disposed outside the rotating body 210 in this embodiment, the fixed-side magnets 241 may be disposed inside the rotating body 210, that is, between the rotating shaft 202 and the rotating-side magnets 221, etc. Alternatively, the fixed-side magnets 241 may be disposed both outside and inside the rotating body 210. Even in this case, the same operations and effects as those of the above-described embodiment can be achieved.

[0148] While three rotating-side magnets 221 are provided in this embodiment, the number of rotating-side magnets provided may be one or more than three. Furthermore, when multiple rotating-side magnets 221 are provided, they may not be evenly spaced but may be arranged irregularly. In short, the number of rotating-side magnets provided and the spacing between them can be appropriately set according to specifications. Even in this case, the same functions and effects as those of the above-described embodiment can be achieved.

[0149] In this embodiment, the plate-shaped magnet 320 is moved vertically by the interaction between the rotating side magnet 221 and the plate-shaped magnet 320. However, the plate-shaped magnet 320 may be moved vertically mechanically using a linkage mechanism, or electrically using a solenoid, a motor, or the like. In short, any method that can move the plate-shaped magnet 320 vertically, whether mechanical or electrical, will suffice.

[0150] Next, based on Figure 38 to Figure 40-2, the seventh embodiment will be described. In addition, the seventh embodiment will be described with the focus on the differences between it and the fifth embodiment. The differences of the seventh embodiment are mainly: Figure 27 The swing mechanisms 231, 232, and 233 in the thrust generating mechanism shown in (a) are respectively used Figure 38 The forward and backward movement mechanism 410 is shown instead.

[0151] like Figures 38 to 40-2 As shown, the front-back moving mechanism 410 includes: a first fixed side magnet 420 and a second fixed side magnet 421, which are formed into the same structure as the rotating side magnet 221, etc.; and a limiting portion 430, which limits the plate-shaped magnets 420 and 421 to move only in the front-back direction.

[0152] like Figure 38 As shown in (c), the first fixed side magnet 420 is similar to the rotating side magnet 221, and has a polarity of N pole on the peripheral surface (one end surface) above the boundary line MC and a polarity of S pole on the peripheral surface (the other end surface) below the boundary line MC (refer to Figure 11 (b) (Comparison). The second fixed-side magnet 421 is identical to the first fixed-side magnet 420, except that its orientation is 180 degrees different from that of the first fixed-side magnet 420. The second fixed-side magnet 421 has an S-pole polarity on its circumferential surface (one end surface) above the boundary line MC and an N-pole polarity on its circumferential surface (the other end surface) below the boundary line MC.

[0153] The limiting portion 430 includes: a lower support portion 431, which is placed on the placement surface G; an upper support portion 432, which is above the lower support portion 431 and extends parallel to the lower support portion 431; a connecting portion 433, which connects these supporting portions 431 and 432; a swing shaft 434, which is supported by the upper and lower support portions 431 and 432; and a shell CS, which is made of a non-magnetic body such as resin and covers the entire fixed side magnets 420 and 421. The shell CS is installed so as to be able to swing freely relative to the swing shaft 434. Inside the shell CS, the first fixed side magnet 420 and the second fixed side magnet 421 are arranged on the left and right sides of the swing shaft 434 in a state of standing upright along the swing shaft 434. In addition, on the back side of the shell CS, a position behind the first fixed side magnet 420 is provided to control the forward ( Figure 38 A spring SP1 (so-called push spring) that applies force to the left in (b) is provided at the rear of the second fixed-side magnet 421 to push the first fixed-side magnet 420 backward ( Figure 38 (b) A spring SP2 (so-called tension spring) that applies force to the right.

[0154] like Figure 39As shown, the rotating-side magnet 221 has the same dimensions as the first fixed-side magnet 420 and the second fixed-side magnet 421. When the rotating-side magnet 221 and the second fixed-side magnet 421 face each other, the polarity of one end face (the north pole) of the rotating-side magnet 221 and the polarity of one end face (the south pole) of the second fixed-side magnet 421 facing the first end face are different. Furthermore, the polarity of the other end face (the south pole) of the rotating-side magnet 221 and the polarity of the other end face (the north pole) of the second fixed-side magnet 421 facing the second end face are different. Therefore, an attractive force acts between the rotating-side magnet 221 and the second fixed-side magnet 421. On the other hand, when the rotating side magnet 221 and the first fixed side magnet 420 face each other, contrary to the case where the rotating side magnet 221 and the first fixed side magnet 421 face each other, one end face (N pole) of the rotating side magnet 221 and one end face (N pole) of the second fixed side magnet 421 facing the one end face have the same polarity, and the other end face (S pole) of the rotating side magnet 221 and the other end face (S pole) of the second fixed side magnet 421 facing the other end face have the same polarity, so a repulsive force acts between the rotating side magnet 221 and the second fixed side magnet 421. It should be noted that, in Figure 39 In FIG. 1 , only the state in which the rotating-side magnet 221 and the second fixed-side magnet 421 face each other is shown, and the state in which the rotating-side magnet 221 and the first fixed-side magnet 420 face each other is omitted.

[0155] The first fixed side magnet 420 and the second fixed side magnet 421 can be moved forward and backward by the swinging of the housing CS. Specifically, when there is no magnetic force or the magnetic force is small between the second fixed side magnet 421 and the rotating side magnet 221, etc., in other words, when the attractive force between the rotating side magnet 221, etc. and the second fixed side magnet 421, etc. is smaller than the force of the spring SP2, the second fixed side magnet 421 is located in the first initial position (in other words, it can also be called the initial position with the first fixed side magnet 421). Figure 38 and Figure 40-1 (a) shows the first separation position where the rotating side magnet 221 is separated). From this state, the housing CS swings around the swing shaft 434, and the second fixed side magnet 421 moves forward. That is, the housing CS overcomes the force of the spring SP2 and moves forward. Figure 38 (b) is inclined in the clockwise direction, and the second fixed side magnet 421 is forward (at Figure 38 (b) is the left direction) and reaches a close position with the rotating side magnet 221 and the like (reference Figure 40-1 (a) to (c)).

[0156] On the other hand, when there is no magnetic force or the magnetic force is small between the first fixed side magnet 420 and the rotating side magnet 221, etc., in other words, when the attractive force between the rotating side magnet 221, etc. and the first fixed side magnet 420, etc. is smaller than the force of the spring SP1, the first fixed side magnet 420 is located at Figure 38 and Figure 40-1 (a) The second initial position. From this state, the housing CS swings around the swing shaft 434, so that the first fixed side magnet 420 moves backward. That is, the housing CS overcomes the force of the spring SP1 and moves toward Figure 38 (b) is tilted in the clockwise direction, and the second fixed side magnet 421 is tilted backward (at Figure 38 (b) is the right direction) and reaches a rear position further back than the second initial position (reference Figure 40-1 (a) to (c)).

[0157] Next, based on the above structure, the function of the thrust generating device of the seventh embodiment will be described. Figure 40-1 As shown in (a), the rotating side magnet 221 is located upstream of the second fixed side magnet 421 in the direction of rotation, and the rotating side magnet 221 and the second fixed side magnet 421 are separated (in other words, the second fixed side magnet 421 is located between the rotating side magnets 221 and 222, also known as Figure 27 (a) The fixed side magnet 241 is replaced by the plate-shaped magnet 421. Figure 40-1 and Figure 40-2 (The rotating-side magnet 222 is omitted from the illustration.) Under the forces of springs SP1 and SP2, the first fixed-side magnet 420 and the second fixed-side magnet 421 are located in the first and second initial positions, respectively. In this state, the attractive force between the second fixed-side magnet 421 and the rotating-side magnet 221 attracts the rotating-side magnet 221, causing the rotating body 210 to rotate.

[0158] The rotating body 210 rotates due to the attraction between the rotating side magnet 221 and the second fixed side magnet 421 (the rotating body 210 continues to rotate), and when the rotating side magnet 221 and the plate magnet 320 are close to each other, as shown in FIG. Figure 40-1 As shown in (b), the attractive force between the rotating magnet 221 and the second fixed magnet 421 becomes greater than the force of the spring SP1, causing the housing CS to swing and the second fixed magnet 421 to move forward. Meanwhile, the first fixed magnet 420 moves backward due to the swinging of the housing CS.

[0159] Thereafter, the rotating body 210 further rotates (the rotating body 210 continues to rotate) due to the attraction between the rotating side magnet 221 and the second fixed side magnet 421, and as shown in FIG. Figure 40-1 As shown in FIG. 3 , in a state where the rotating side magnet 221 and the second fixed side magnet 421 face each other, that is, where the rotating side magnet 221 and the second fixed side magnet 421 are closest to each other and the attraction between them is greatest, the second fixed side magnet 421 moves further forward due to the attraction between the rotating side magnets 221 and is located in the approaching position. On the other hand, the first fixed side magnet 420 moves further rearward and is located in the rear position.

[0160] Thereafter, the rotating body 210 further rotates due to its rotational potential energy (the rotating body 210 continues to rotate), and as shown in FIG. Figure 40-2 As shown in (d), the rotating side magnet 221 moves to the downstream side of the rotation direction relative to the second fixed side magnet 421, so that the attractive force between the magnets 221 and 421 is weaker than Figure 40-1 As shown in (c), the rotating magnet 221 faces the second fixed magnet 421, so the second fixed magnet 421 moves to the first initial position due to the biasing force of the spring SP2. Meanwhile, the first fixed magnet 420 also moves to the second initial position.

[0161] Thereafter, the rotating body 210 further rotates (the rotating body 210 continues to rotate), and as shown in FIG. Figure 40-2 As shown in (e), at the position where the rotating-side magnet 221 and the first fixed-side magnet 420 face each other (i.e., the position where the rotating-side magnet 221 and the first fixed-side magnet 420 are closest to each other), a repulsive force acts between them. As a result, the repulsive force that pushes the rotating-side magnet 221 in the direction of rotation is converted into a thrust force for rotation, further rotating the rotating body 210.

[0162] Thereafter, the rotating body 210 further rotates (the rotating body 210 continues to rotate), and as shown in FIG. Figure 40-2 As shown in (f), the rotating magnet 221 moves further downstream in the direction of rotation relative to the first and second fixed magnets 420 and 421, separating the rotating magnet 221 from the plate magnet 320. In this state, the magnetic force between the rotating magnet 221 and the first and second fixed magnets 420 and 421 further weakens, causing the first and second fixed magnets 420 and 421 to return to their respective first and second initial positions. Thereafter, the same action is repeated (in other words, the same action is repeated between the rotating magnets 222 and 223 and the first and second fixed magnets 420 and 421), causing the rotating body 210 to continue rotating.

[0163] As described above, in the seventh embodiment, the rotating body 210 is rotated by being attracted by the magnetic force between the rotating side magnet 221 etc. and the second fixed side magnet 421, and the rotating body 210 can be smoothly rotated by the interaction between the rotating side magnet 221 etc. and the second fixed side magnet 421 (the second fixed side magnet 421 moves back and forth due to the strength of the attractive force between the rotating side magnet 221 etc. and the second fixed side magnet 421), and the rotational thrust generated by the repulsive force between the first fixed side magnet 420 and the rotating side magnet 221 etc.

[0164] It should be noted that although two fixed-side magnets, namely the first and second fixed-side magnets 420 and 421, are used in this embodiment, a single fixed-side magnet may be used. Even in this embodiment, the same functions and effects as those of this embodiment can be achieved.

[0165] As a modification example using only a single fixed side magnet, specifically, Figure 41 As shown, a plate-shaped third fixed side magnet 440 that is the same as the plate-shaped magnet 320 in the sixth embodiment is used to replace the first and second fixed side magnets 420 and 421. In addition, a limiting portion 430A that limits the third fixed side magnet 440 to be able to move only forward and backward, which is used instead of the limiting portion 430 of the above-mentioned forward and backward moving mechanism 410, roughly has: an outer cylinder portion 450, fixed to the connecting portion 433; an inner cylinder portion 451, which can move forward and backward inside the outer cylinder portion 450; and a spring SP3 (so-called tension spring) that applies force to the third fixed side magnet 440 toward the rear. The third fixed side magnet 440 can move forward and backward by the forward and backward movement of the inner cylinder portion 451. That is, when the repulsive force between the rotating side magnet 221 and the third fixed side magnet 440 is smaller than the force of the spring SP3, the third fixed side magnet 440 is located. Figure 42 (a) The third initial position shown. From this state, the inner cylinder 451 overcomes the force of the spring SP3 and moves forward, so that the third fixed side magnet 440 moves forward, and moves further forward than the third initial position, and is located at a position close to the rotating side magnet 221. It should be noted that Figure 42 In FIG. 4 , the third fixed-side magnet 440 is drawn as a black circle to make the relationship between the magnetic poles easier to understand.

[0166] like Figure 42As shown in FIG. 1 , the rotating-side magnet 221 is located upstream in the rotational direction relative to the third fixed-side magnet 440. With the rotating-side magnet 221 separated from the second fixed-side magnet 421, the third fixed-side magnet 440 is positioned in a third initial position due to the biasing force of the spring SP3. In this position, the attractive force between the third fixed-side magnet 440 and the rotating-side magnet 221 attracts the rotating-side magnet 221, causing the rotating body 210 to rotate.

[0167] Thereafter, in a state where the rotating side magnet 221 and the third fixed side magnet 440 are close to each other, as shown in FIG. Figure 42 As shown in (b), the attractive force between the rotating-side magnet 221 and the third fixed-side magnet 440 becomes greater than the urging force of the spring SP3, so that the third fixed-side magnet 440 moves forward.

[0168] Afterwards, if Figure 42 As shown in (c), in the state where the rotating side magnet 221 and the third fixed side magnet 440 are closest to each other and the attraction between them is the greatest, the third fixed side magnet 440 moves further forward due to the attraction between it and the rotating side magnet 221 and is located at the close position. Thereafter, the rotating body 210 further rotates under the action of its rotational potential energy (the rotating body 210 continues to rotate), and as shown in FIG. Figure 42 As shown in (d), the rotating magnet 221 moves downstream in the rotational direction relative to the third fixed magnet 440, thereby weakening the attractive force between the magnets 221 and 440. Therefore, the third fixed magnet 440 moves to the third initial position under the biasing force of the spring SP3.

[0169] Thereafter, rotating magnet 221 moves further downstream in the rotational direction relative to third fixed magnet 440, separating rotating magnet 221 from third fixed magnet 440. In this state, the magnetic force between rotating magnet 221 and third fixed magnet 440 further weakens, causing third fixed magnet 440 to return to its third initial position. Thereafter, the same action repeats (in other words, the same action repeats between rotating magnets 222 and 223 and third fixed magnet 440), causing rotating body 210 to continue rotating.

[0170] In the present embodiment and its modifications, although permanent magnets are used on both the rotating side and the fixed side, such as the rotating side magnet 221 and the like and the fixed side magnets 420, 421, 440 (hereinafter sometimes referred to as "the fixed side magnets 420, etc."), a rotating side component or a fixed side component made of a magnetic material (either the rotating side or the fixed side is a magnetic material that can withstand the magnetic force from a magnet such as iron or steel) may be used, as shown in (1) or (2) below. Even in this case, the same operation and effect as in the present embodiment and its modifications can be achieved. (1) A combination of a rotating-side member including the rotating-side magnet 221 and the like as a magnetic body and each of the fixed-side magnets 420 and the like. (2) A combination of the rotating-side magnet 221 and the like and a fixed-side member including the fixed-side magnets 420 and the like as magnetic bodies.

[0171] In this embodiment and its modifications, the fixed-side magnets 241 are disposed outside the rotating body 210. However, the fixed-side magnets 241 may be disposed inside the rotating body 210, that is, between the rotating shaft 202 and the rotating-side magnets 221. Alternatively, the fixed-side magnets 241 may be disposed both outside and inside the rotating body 210. Even in this case, the same operations and effects as those of the above-described embodiment can be achieved.

[0172] While three rotating-side magnets 221 are provided in this embodiment and its variations, the number of rotating-side magnets provided may be one or more than three. Furthermore, when multiple rotating-side magnets 221 are provided, they may not be evenly spaced but may be arranged irregularly. In short, the number of rotating-side magnets provided and the spacing between them can be appropriately set according to specifications. Even in this case, the same functions and effects as those of the above-described embodiment can be achieved.

[0173] In this embodiment and its variations, a spring or other biasing member is used as a mechanical structure for each fixed-side magnet 420, thereby causing each fixed-side magnet 420 to advance and retract (move forward and backward). However, other mechanical structures, such as a link mechanism, or a solenoid, motor, or the like may also be used to electrically advance and retract each fixed-side magnet 420. In short, whether mechanical or electrical means are used, any method that can advance and retract the position of each fixed-side magnet 420 will suffice.
