Figure 1 In the text, the left and right directions are referred to as the width direction or the Y direction, the left direction is referred to as one side of the width direction or the "+Y direction", and the right direction is referred to as the other side of the width direction or the "-Y direction". Figure 1 In the diagram, the up-down direction is referred to as the longitudinal direction or the Z direction, the up direction is referred to as the "+Z direction", and the down direction is referred to as the "-Z direction". In addition, the direction in which the window glass is raised is sometimes referred to as the up-down direction (Z direction), the direction in which the window glass rises is referred to as the "+Z direction", and the direction in which the window glass falls is referred to as the "-Z direction".

[0016] The window regulator 1 is supported by a door panel (not shown) of a vehicle. The window regulator 1 is a mechanism for moving a window glass (not shown) as a moving object up and down.

[0017] like Figure 1 and Figure 2As shown, the window regulator 1 mainly includes a guide rail 31 , a carrier plate 32 , an ascending cable 33 , a descending cable 34 , and a driving unit 35 .

[0018] The guide rail 31 is provided along the window glass lifting direction (Z direction) and is a member for guiding the carrier plate 32 in the window glass lifting direction. The guide rail 31 extends substantially in the vehicle vertical direction (Z direction) and is specifically provided to be slightly inclined with respect to the window glass to be mounted.

[0019] Figure 3 3 is a perspective view of a carrier plate 32 assembled to a guide rail 31. The carrier plate 32 is a component that holds the lower end of the window glass and engages with the guide rail 31 to be slidably guided in the lifting direction of the window glass. The carrier plate 32 is lifted and lowered along the edge of the guide rail 31. The structure of the carrier plate 32 will be described in detail later.

[0020] An upper cable guide 45 (see FIG. 4 ) is provided at the upper end of the guide rail 31 as a direction changing member for changing the moving direction of the ascending cable 33 . Figure 1 ).

[0021] like Figure 1 and Figure 2 As shown, a driving unit 35 for winding and releasing the ascending cable 33 and the descending cable 34 is provided at the lower end of the guide rail 31. The driving unit 35 includes a reel housing 51, a reel (not shown) and a driving motor 56. The reel housing 51 is mounted on the lower end of the guide rail 31 to fix the guide rail 31 to a door panel (not shown) of the vehicle.

[0022] The reel case 51 rotatably supports the reel. The drive motor 56 is integrally mounted on the reel case 51 and rotationally drives the reel in both forward and reverse directions.

[0023] The ascending cable 33 and the descending cable 34 are components for pulling the carrier plate 32 in the vertical direction (Z direction), and a known cable formed by twisting a plurality of metal wires or resin fiber wires can be used. One end of the ascending cable 33 is connected to the carrier plate 32, is wound around the upper cable guide 45, and the other end is connected to the drum. One end of the descending cable 34 is connected to the carrier plate 32, and the other end is connected to the drum.

[0024] The drive motor 56 rotates the winding drum to wind up and unwind the ascending cable 33 and the descending cable 34 .

[0025] Figure 4This is a forward view when the carrier is viewed from the other side in the thickness direction. A terminal 33a (corresponding to the "end of the cable" of the present invention) and a terminal 34a (corresponding to the "end of the cable" of the present invention) are provided at one end of the ascending cable 33 or the descending cable 34. The terminal 33a and the terminal 34a are formed, for example, by die-casting of a metal material, and have a base end portion for mounting one end of the ascending cable 33 or the descending cable 34 and a flange portion having an outer diameter larger than that of the base end portion. The base end portion is formed in a cylindrical shape or a truncated cone shape, and one end of the ascending cable 33 or the descending cable 34 is fixed thereto by bonding, welding, bolting, or other methods.

[0026] The coil spring 85 and the coil spring 87 are attached to the terminal 33a and the terminal 34a, respectively. The coil spring 85 and the coil spring 87 are biasing members for biasing the terminal 33a and the terminal 34a in the direction of eliminating the slack of the ascending cable 33 and the descending cable 34.

[0027] (2) Guide rail

[0028] The guide rail 31 is gently curved in accordance with the curvature of the window glass of the automobile. The guide rail 31 is made of, for example, stainless steel, aluminum alloy, or other hard materials.

[0029] exist Figure 1 The U-shaped cross section C of the guide rail 31 viewed from above is overlapped in the front view of the depicted guide rail 31. The guide rail 31 includes a base 37, side wall portions 38a, 38b, and flange portions 39a, 39b. The base 37 has a predetermined length in the width direction (Y direction) and extends in the up-down direction (Z direction). The side wall portion 38a is located at an end portion on one end side (+Y direction) in the width direction of the base 37 and is erected from the long side of the base 37 along the length direction (Z direction) of the base 37. The side wall portion 38b is located at an end portion on the other end side (-Y direction) in the width direction of the base 37 and is erected from the long side of the base 37 along the length direction (Z direction) of the base 37.

[0030] The flange portion 39 a is bent at a right angle from the side wall portion 38 a , and extends in parallel with the base portion 37 toward one end side in the width direction (+Y direction).

[0031] The flange portion 39 b is bent at a right angle from the side wall portion 38 b , and extends in parallel with the base portion 37 toward the other end side in the width direction (−Y direction).

[0032] (3) Roll housing

[0033] The reel housing 51 has a main body 51a having an engaging portion engaged with the guide rail 31 and a cylindrical reel accommodating portion. A cylindrical recessed portion for accommodating the reel is formed in the main body 51a. An ascending cable outlet groove 57 and a descending cable outlet groove 59 are formed in the main body 51a, and the ascending cable outlet groove 57 and the descending cable outlet groove 59 are used to allow the ascending cable 33 and the descending cable 34 to pass through the recessed portion and be led out to the outside.

[0034] (4) Structure of carrier board

[0035] Next, refer to Figure 4 , Figure 5 and Fig. 6A The structure of the carrier plate 32 in this embodiment will be described. Figure 5 This is a view when the carrier plate 32 is viewed from above. Fig. 6A It is a partial cross-sectional view showing the structure of the carrier plate 32 in this embodiment.

[0036] The carrier plate 32 has a main body 32a. The main body 32a is a base and may be any part as long as it forms other structures.

[0037] The mounting parts 71 and 73 are provided on the surface 32b (corresponding to the "second surface" of the present invention) provided on the main body 32a and located on one side in the thickness direction (+X direction). The mounting parts 71 and 73 are provided for mounting a bracket (not shown) for holding a window glass (not shown). In addition, the guide groove 75 (corresponding to the "fitting part" of the present invention), the anti-rotation claw 77, the elastic claw 78, the rising side terminal bracket 79 (corresponding to the "accommodation part" of the present invention) and the descending side terminal bracket 81 (corresponding to the "accommodation part" of the present invention) are provided on the surface 32c provided on the other side in the thickness direction (-X direction) of the main body 32a.

[0038] The guide groove 75 is arranged at the center of the width direction (Y direction). The guide groove 75 has: an opening 75a, which opens to the other side (-X direction) of the thickness direction of the main body 32a; a groove 75b, which extends from the opening 75a to one side (+X direction) of the thickness direction; and a groove 75c, which extends from the bottom of the groove 75b to one side (+Y direction) of the width direction. The groove 75b is provided for the side wall portion 38a (refer to Fig. 6A ) slides. In addition, the groove 75c is provided for the flange portion 39a of the guide rail 31 (refer to Fig. 6A ) sliding slot.

[0039] The carrier plate 32 is assembled on the guide rail 31. Fig. 6AIn the state shown, in other words, in the state where the guide groove 75 allows the side wall portion 38a and the flange portion 39a to slide, the gap provided between the groove 75b and the side wall portion 38a is small. In addition, the gap provided between the groove 75c and the flange portion 39a is small. The cross-sectional shape of the side wall portion 38a and the flange portion 39a in the XY plane is L-shaped. As a result, the central portion of the carrier plate 32 located in the center in the width direction is unlikely to shake in the thickness direction (X direction) and the width direction (Y direction) relative to the side wall portion 38a and the flange portion 39a.

[0040] The anti-rotation claw 77 is arranged on the other side (-Y direction) in the width direction than the guide groove 75. The anti-rotation claw 77 prevents the carrier plate 32 from rotating around the guide groove 75. The anti-rotation claw 77 includes: a wall 77a extending from a surface 32c located on the other side (-X direction) in the thickness direction of the main body 32a in the -X direction; and a protrusion 77b protruding from the front end of the wall 77a to one side in the width direction (+Y direction). The protrusion 77b includes a first claw portion 77b1 and a second claw portion 77b2. The first claw portion 77b1 and the second claw portion 77b2 are arranged separately in the up-down direction (Z direction).

[0041] The elastic claw 78 is arranged between the guide groove 75 and the anti-rotation claw 77 in the width direction (Y direction). It has: a base end portion 78a, which is arranged on the surface 32c provided on the other side (-X direction) of the thickness direction of the main body 32a; an extension portion 78b, which extends from the base end portion 78a toward the other side (-X direction) in the thickness direction to the other side (-Y direction) in the width direction; and a front end portion 78c, which protrudes from the extension portion 78b to the other side (-Y direction) in the width direction in a manner close to the protrusion 77b. The front end portion 78c is arranged between the first claw portion 77b1 and the second claw portion 77b2 when viewed from the thickness direction. In addition, the front end portion 78c is located on the thickness direction side (+X direction) than the first claw portion 77b1 and the second claw portion 77b2.

[0042] The elastic claw 78 has elasticity, and therefore has a restoring force that tends to return to the other side (−X direction) in the thickness direction when the elastic claw 78 is bent to one side (+X direction) in the thickness direction due to an external force or the like.

[0043] Next, refer to Figure 4 , Figure 5 , Fig. 6A and Figure 6B The relative positional relationship between the anti-rotation claw 77 and the elastic claw 78 will be described. Figure 6B The anti-rotation claw 77 has a first claw portion 77b1 and a second claw portion 77b2. The elastic claw 78 has a front end portion 78c (see Figure 4 and Figure 6B), the front end portion 78c is arranged between the first claw portion 77b1 and the second claw portion 77b2 when viewed from the thickness direction.

[0044] In the following assembly operation of the carrier plate 32 in the present embodiment and the assembly operation of the carrier plate 320 in the comparative example, the positional relationship with the obstacle is applied to the ascending cable 33 for description, but the present invention is not limited thereto and may also be applied to the descending cable 34 .

[0045] In the assembly process of the window regulator 1, before the carrier plate 32 is assembled to the guide rail 31, the end 33a of the ascending cable 33 is assembled to the carrier plate 32. Then, the ascending cable 33 is laid between the guide rail 31 and the carrier plate 32. Thus, in the conventional carrier plate 320, before the carrier plate 32 is assembled to the guide rail 31, the end 33a of the ascending cable 33 is assembled to the carrier plate 32. Figure 6B In the assembly operation shown, the ascending cable 33 may intrude between the elastic claw 78 and the anti-rotation claw 77. However, in the carrier plate 32 of the present embodiment, the front end portion 78c is arranged between the first claw portion 77b1 and the second claw portion 77b2 when viewed from the thickness direction, so that the ascending cable 33 can be prevented from intruding between the first claw portion 77b1 and the second claw portion 77b2.

[0046] The carrier plate 32 is assembled on the guide rail 31. Fig. 6A In the state shown, in other words, in a state where the groove (gap) provided between the front end portion 78c and the protrusion 77b allows the flange portion 39b to slide, the front end portion 78c and the protrusion 77b sandwich the flange portion 39b in the thickness direction (X direction). In this case, the front end portion 78c presses the flange portion 39b to the protrusion 77b side (-X direction). That is, the front end portion 78c contacts the surface 39b1 (corresponding to the "first surface" of the present invention) provided on the flange portion 39b on one side (+X direction) in the thickness direction. In addition, the protrusion 77b contacts the surface 39b2 (corresponding to the "second surface" of the present invention) provided on the other side (-X direction) in the thickness direction of the flange portion 39b. As a result, the end portion of the carrier plate 32 on the other side (-Y direction) in the width direction is less likely to shake relative to the flange portion 39b in the thickness direction (X direction).

[0047] Thus, when the carrier plate 32 is assembled to the guide rail 31, Fig. 6A In the state shown, the guide groove 75 allows the flange portion 39a provided on the guide rail 31 to slide. The groove (gap) provided between the protrusion 77b and the front end portion 78c allows the flange portion 39b provided on the guide rail 31 to slide. The flange portion 39b is locked by the protrusion 77b in the thickness direction (X direction), so that the carrier plate 32 stops rotating around the flange portion 39a.

[0048] In addition, when the carrier plate 32 is assembled to the guide rail 31, Fig. 6AIn the state shown, the closed space CS is formed by the carrier plate 32 and the guide rail 31. The rising side cable 33 is located at the central part of the width direction (Y direction) in the closed space CS, and passes through the closed space CS in the vertical direction (Z direction). In the closed space CS, there is no obstacle that hinders the movement of the rising side cable 33 in the width direction (Y direction). Therefore, the rising side cable 33 can move from one position of the position close to the side wall portion 38a side and the position close to the side wall portion 38b side to the other position in the closed space CS. Since there is no obstacle that hinders the movement of the rising side cable 33 in the width direction (Y direction) in the closed space CS, even if it is assumed that the rising side cable 33 is located at the position close to the side wall portion 38b during the assembly operation of the carrier plate 32, before the assembly operation of the carrier plate 32 is completed, the rising side cable 33 can be moved from the position close to the side wall portion 38b side to the central part of the width direction (Y direction) in the closed space CS. In the following description, the position of the ascending cable 33 when the assembly work of the carrier plate 32 is completed is referred to as the "correct position". Fig. 6A In FIG. 1 , the rising side cable 33 in the correct position is indicated by a solid line. In addition, the position of the rising side cable 33 other than the correct position is referred to as an "incorrect position". Fig. 6A In FIG. 1 , the rising side cable 33 in the wrong position is indicated by a dotted line.

[0049] (Comparative Example)

[0050] Next, refer to Fig. 7A The structure of the carrier plate 320 in the comparative example will be described. Fig. 7A It is a partial cross-sectional view showing the structure of a carrier plate 320 in a comparative example. Figure 7B 1 is a partial cross-sectional view showing the carrier plate 320 during the assembling operation in the comparative example. Figure 7C It is an arrow view when the elastic claw in the comparative example is viewed from the other side in the width direction. In the description of the comparative example, the structure different from the structure of the carrier plate 32 in the present embodiment is described, and the same structure is denoted by the same reference numeral and its description is omitted.

[0051] The carrier plate 320 has a main body 32 a , mounting portions 71 , 73 , a guide groove 75 , an anti-rotation claw 77 , an elastic claw 780 , an ascending side end bracket 79 , and a descending side end bracket 81 .

[0052] The elastic claw 780 in the comparative example is arranged between the guide groove 75 and the anti-rotation claw 77 in the width direction (Y direction). The elastic claw 780 has a base end portion 780a, and the base end portion 780a is arranged on the surface 32c provided on the main body 32a and located on the other side (-X direction) in the thickness direction. In addition, the elastic claw 780 has an extension portion 780b (see Figure 7C), the extension portion 780b extends from the base end portion 780a in the downward direction (-Z direction) to the other side in the thickness direction (-X direction) along an inclined direction. The front end of the extension portion 780b extends in an arc shape toward one side in the thickness direction (+X direction). The extension portion 780b involved in the comparative example is different from the extension portion 78b in the present embodiment, which extends from the base end portion 780a toward the other side in the thickness direction (-X direction) toward the other side in the width direction (-Y direction) along an inclined direction. When the carrier plate 320 is assembled to the guide rail 31 Fig. 7A In the state shown, the extension portion 780b contacts the surface located on one side in the thickness direction (+X direction) of the base 37. That is, the elastic claw 780 is configured to connect the surface 32c located on the other side in the thickness direction of the body 32a with the surface located on one side in the thickness direction (+X direction) of the base 37.

[0053] The carrier plate 320 is assembled on the guide rail 31. Fig. 7A In the illustrated state, a closed space CS is formed by the carrier plate 32 and the guide rail 31. The closed space CS is divided by the elastic claw 780 into a space CS1 located on the side wall portion 38a and a space CS2 located on the side wall portion 38b.

[0054] When the closed space CS is divided into the space CS1 and the space CS2 by the elastic claws 780 , the ascending cable 33 is located in the space CS1 on the side of the side wall portion 38 a and passes through the space CS1 in the vertical direction (Z direction).

[0055] Since the extension portion 780b is present in the closed space CS as an obstacle that hinders the movement of the ascending cable 33 in the width direction (Y direction), the ascending cable 33 is hindered from moving from one of the positions close to the side wall portion 38a (space CS1) and the position close to the side wall portion 38b (space CS2) to the other position. In addition, in the following description, it is assumed that the position (correct position) that the carrier plate 320 should be in when the assembly work is completed is the position close to the side wall portion 38a (space CS1). Fig. 7A In FIG. 1 , the rising-side cable 33 in the correct position is indicated by a solid line, and the rising-side cable 33 in the position close to the side wall portion 38 b (incorrect position) is indicated by a dotted line.

[0056] (Assembly Operation of Carrier Board in Comparative Example)

[0057] Next, refer to Fig. 7A and Figure 7B The assembly operation of the carrier plate 320 in the comparative example will be described.

[0058] In the assembly operation of the carrier board 320, as Figure 7BAs shown, the guide groove 75 is embedded in the side wall portion 38a and the flange portion 39a provided on the guide rail 31 as the end portion located on one side in the width direction (+Y direction), so that the carrier plate 320 is around the end portion on one side in the width direction. Figure 7B At this time, there is a case where the ascending cable 33 is located at a position close to the side wall portion 38b, which is an incorrect position, due to slack or the like. Figure 7B The dotted line in the figure indicates the rising side cable in the wrong position.

[0059] Next, the carrier plate 320 is rotated counterclockwise around the end portion on one side in the width direction, as shown in FIG. Fig. 7A As shown, the flange portion 39b is locked to the anti-rotation claw 77. In this way, the carrier plate 320 is assembled to the guide rail 31. At this time, there is still a case where the ascending side cable 33 is located at a position close to the side wall portion 38b, which is an incorrect position. In other words, there is a case where the ascending side cable 33 is located in the space CS2.

[0060] After the carrier plate 320 is assembled to the guide rail 31, tension is applied to the ascending cable 33. As a result, the ascending cable 33 eliminates slack and the like and attempts to move from the position close to the side wall portion 38b, which is an incorrect position, toward the position close to the side wall portion 38a, which is a correct position (space CS1), in other words, attempts to move toward a straight line connecting the ascending cable lead-out groove 57 of the drum housing 51a and the ascending cable 33 lead-out portion of the upper pulley 45. In this case, since the closed space CS is divided into the space CS1 and the space CS2 by the elastic claw 780, the elastic claw 780 hinders the movement of the ascending cable 33. As a result, the ascending cable 33 is not laid out at the correct position, and therefore, the assembly operation of the carrier plate 320 needs to be performed again, and the assembly workability of the carrier plate 320 may be reduced.

[0061] (Assembly Operation of Carrier Board in the Present Embodiment)

[0062] Next, refer to Fig. 6A and Figure 6B The assembly operation of the carrier plate 32 in the present embodiment will be described. Figure 6B 2 is a partial cross-sectional view showing the carrier plate during the installation operation in the present embodiment. In the following description, the position (correct position) of the carrier plate 32 when the installation operation is completed is assumed to be the position of the center portion in the width direction (Y direction) of the closed space CS. Figure 6B In FIG. 1 , the rising side cable 33 in the correct position is indicated by a solid line. In addition, the rising side cable 33 in the position close to the side wall portion 38b, which is an incorrect position, is indicated by a dotted line.

[0063] In the assembly operation of the carrier board 32, as Figure 6BAs shown, the guide groove 75 is embedded in the side wall portion 38a and the flange portion 39a provided on the guide rail 31 as the end portion located on one side in the width direction (+Y direction), so that the carrier plate 32 is around the end portion on one side in the width direction. Figure 6B At this time, the ascending cable 33 may be located at a position close to the side wall portion 38b, which is an incorrect position, due to slack or the like.

[0064] Next, the carrier plate 32 is rotated counterclockwise around the end portion on one side in the width direction, as shown in FIG. Fig. 6A As shown, the flange portion 39b is locked to the anti-rotation claw 77. In this way, the carrier plate 32 is assembled to the guide rail 31. At this time, there is still a case where the ascending side cable 33 is located at a position close to the side wall portion 38b, which is an incorrect position.

[0065] After the carrier plate 32 is assembled to the guide rail 31, tension is applied to the ascending cable 33. As a result, the ascending cable 33 eliminates slack and moves from the wrong position to the position close to the side wall portion 38a, which is the correct position. In this case, since there is no obstacle that hinders the movement of the ascending cable 33 in the closed space CS, the ascending cable 33 is laid from the wrong position to the correct position. As a result, it is not necessary to re-assemble the carrier plate 32, so the assembly workability of the carrier plate 32 can be improved.

[0066] The carrier plate 32 in the above-mentioned embodiment is guided and slidably on the guide rail 31 by transmitting the driving force of the driving part 35 by the ascending side cable 33 and the descending side cable 34, wherein the carrier plate comprises: a base 37; a guide groove 75, which is engaged with the guide rail 31; an anti-rotation claw 77, which is arranged separately from the guide groove 75 on one side in the width direction of the base 37 to prevent the carrier plate 32 from rotating around the guide groove 75 relative to the guide rail 31; an ascending side end bracket 79 and a descending side end bracket 81, which are arranged on the other side in the width direction of the base 37 relative to the guide groove 75 to accommodate the respective ends of the ascending side cable 33 and the descending side cable 34; and an elastic claw 78, which contacts the surface of the flange portion 39b located on one side in the thickness direction (+X direction).

[0067] With the above structure, during the installation operation of assembling the carrier plate 32 to the guide rail 31, the elastic claw 78 contacts the surface 39b1 of the flange portion 39b, so that the movement of the ascending cable 33 is not hindered by the elastic claw 78, compared with a structure in which the elastic claw 78 contacts one side surface in the thickness direction of the base portion 33 of the guide rail 31 on the moving path of the ascending cable 33 in the closed space CS. In other words, the ascending cable 33 is prevented from intruding between the anti-rotation claw 77 and the elastic claw 78. As a result, it is not necessary to re-assemble the carrier plate 32, so even in the structure in which the elastic claw 78 contacts the guide rail 31, the assembly workability of the window regulator 1 can be improved.

[0068] In the carrier plate 32 of the above embodiment, the anti-rotation claw 77 includes a first claw portion 77b1 and a second claw portion 77b2, and the first claw portion 77b1 and the second claw portion 77b2 are arranged separately in the vertical direction (Z direction) of the base 37. The front end portion 78c of the elastic claw 78 is arranged in the area between the first claw portion 77b1 and the second claw portion 77b2, that is, between the first claw portion 77b1 and the second claw portion 77b2 when viewed from above. Even if the ascending side cable 33 attempts to intrude between the anti-rotation claw 77 and the elastic claw 78, the front end portion 78c enters between the first claw portion 77b1 and the second claw portion 77b2, thereby preventing the ascending side cable 33 from intruding. In addition, since the elastic claw 78 is sandwiched between the first claw portion b1 and the second claw portion b2 when viewed from above, the shaking prevention based on the pressing of the elastic claw 78 on the surface 39b1 of the flange portion 39b becomes more effective.

[0069] In addition, in the carrier plate 32 in the above-mentioned embodiment, the elastic claw 78 extends in the width direction (Y direction) of the base 37. When the ascending cable 33 is to be moved in the width direction during the assembly operation of the carrier plate 32, the ascending cable 33 is easily moved along the elastic claw 78. In addition, compared with the case where the elastic claw 78 and the anti-rotation claw 77 are arranged along the up-down direction (Z direction) of the base 37 in the flange portion 39b, the carrier plate can be miniaturized. Moreover, since there is an extension portion 78b extending in an inclined direction from the base end portion 78a of the surface 32c arranged on the other side of the thickness direction (-X direction) set in the main body 32a toward the other side of the thickness direction (-X direction) toward the other side of the width direction (-Y direction), even if the lifting cable 33 contacts the surface on the base 33 side of the elastic claw 78 during the carrier installation operation, the lifting cable 33 can be guided to the base 33 side, and the lifting cable 33 can be further prevented from entering the inner side of the elastic claw 78 (the space on the main body 32a side of the elastic claw 78).

[0070] (Variant 1)

[0071] Next, a modification of the structure for preventing the ascending cable 33 from entering between the anti-rotation claw 77 and the elastic claw 78 will be described.

[0072] In the above embodiment, the anti-rotation claw 77 and the elastic claw 78 may have regions that overlap each other when viewed in a direction orthogonal to the thickness direction (X direction) and the width direction (Y direction) of the carrier plate 32, that is, in the up-down direction (Z direction). Even if the ascending-side cable 33 attempts to intrude between the anti-rotation claw 77 and the elastic claw 78, the anti-rotation claw 77 and the elastic claw 78 overlap in the up-down direction (X direction), thereby preventing the ascending-side cable 33 from intruding.

[0073] (Variant 2)

[0074] In the above embodiment, the gap between the elastic claw 78 and the anti-rotation claw 77 may also be formed to be smaller than the outer diameter of the ascending cable 33. In other words, the gap formed by the 78c of the elastic claw 78 and the protrusion 77b of the anti-rotation claw 77 is smaller than the outer diameter of the ascending cable 33. Thus, even if the ascending cable 33 is separated from the surface on one side of the thickness direction of the main body 33 of the guide rail 31 and is located on the surface 32c side of the carrier plate 32, that is, close to the elastic claw 78, even if the ascending cable 33 wants to intrude between the anti-rotation claw 77 and the elastic claw 78, it cannot pass through the gap, so the ascending cable 33 can be prevented from intruding.

[0075] (Variant 3)

[0076] In the above embodiment, the elastic claw 78 extends in the width direction (Y direction) of the base 37, but the present invention is not limited thereto, and the elastic claw 78 may extend in a direction orthogonal to the width direction (Y direction) of the base 37 and the thickness direction (X direction) of the carrier plate 32, that is, in the up-down direction (Z direction). Even in this case, the anti-rotation claw 77 and the elastic claw 78 form a structure that prevents the ascending side cable 33 from intruding between the anti-rotation claw 77 and the elastic claw 78. In addition, in this case, since the elastic claw 78 and the anti-rotation claw 77 are arranged along the flange portion 39b, it becomes a structure in which the ascending cable 33 is difficult to enter the gap between the elastic claw 78 and the anti-rotation claw 77. Moreover, since the elastic claw 78 is arranged along the flange portion 39b, it is difficult to become a sliding resistance when the carrier plate 32 slides on the guide rail 31.

[0077] (Variant 4)

[0078] In the above embodiment, a gap may be provided between the anti-rotation claw 77 and the elastic claw 78 so that the ascending side cable 33 does not intrude from the thickness direction (X direction) of the carrier plate 32. Thus, even if the ascending side cable 33 attempts to intrude from the thickness direction (X direction) between the anti-rotation claw 77 and the elastic claw 78, the ascending side cable 33 can be prevented from intruding from the anti-rotation claw 77 and the elastic claw 78. Specifically, the gap provided between the anti-rotation claw 77 and the elastic claw 78 may be a curved gap when viewed in the thickness direction (X direction) of the carrier plate 32. Thus, when the ascending side cable 33 arranged in a straight line attempts to intrude from the thickness direction (X direction) into the gap, the ascending side cable 33 can be prevented from intruding because the gap is curved.

[0079] (Variant 5)

[0080] In the above embodiment, the protrusion 77b of the anti-rotation claw 77 has a front end edge extending in the up-down direction (Z direction), and its front end edge may also have a recessed portion, and the central portion of the recessed portion located in the center of the up-down direction is recessed toward the other side (-Y direction) in the width direction when viewed from the thickness direction (X direction). In addition, the front end portion 78c of the elastic claw 78 may also be configured to enter the recessed portion when viewed from the thickness direction. By the front end portion 78c entering the recessed portion, the gap between the anti-rotation claw 77 and the elastic claw 78 will not become a straight line, so it is possible to prevent the ascending side cable 33 arranged in a straight line from invading the gap.

[0081] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the invention. In particular, the plurality of embodiments and modifications described in this specification can be arbitrarily combined as needed.
