Description

[Technical field]

[0001] The present disclosure relates to a hanger. [Background technology]

[0002] There is known a simple baggage sling disclosed in Patent Document 1. Also known is a connecting part in which a ring and a mounting member are connected by a ball joint as disclosed in Patent Document 2. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-245421 A [Patent Document 2] Design Registration No. 1328829 Summary of the Invention [Problem to be solved by the invention]

[0004] It is desirable to facilitate compactness of the hanger when not being used to hang a suspended object. [Means for solving the problem]

[0005] A hanging device according to one aspect of the present disclosure includes a hook in which a hook base and a hook tip are spaced apart from each other to define a hook opening, and a hook extension extends to form a hook recess between the hook base and the hook tip, a main body to which an object to be hung is to be attached, and a mounting member having a connecting part connected to the main body for engagement with the hook base. One of the hook base and the connecting part is provided with a rotating part, and the other of the hook base and the connecting part is provided with a receiving part for receiving the rotating part, and the receiving part receives and holds the rotating part, thereby engaging the mounting member and the hook so that they can rotate relatively. The hook base and the connecting part are configured so that when either the hook or the mounting member is rotated relative to the other so that the mounting member rotates to a position adjacent to the hook tip while the hook and the mounting member are arranged on the same plane, (i) the mounting member can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening, or (ii) the mounting member can cross an imaginary line set at a position corresponding to the minimum opening width of the hook opening.

[0006] In some embodiments, a first imaginary line extending from the hook base to the bottom of the hook recess is represented by the combination of a first vector extending in the depth direction of the hook recess and a second vector extending perpendicular to the first vector from the tip of the first vector to the bottom of the hook recess, and a second imaginary line and a third imaginary line parallel to the first vector are set to sandwich the hook base and the hook tip, and the second imaginary line is set with respect to the hook base and the third imaginary line is set with respect to the hook tip. Assuming that the hook and the mounting member are arranged on the same plane, the mounting member does not cross the third imaginary line during the entire process of rotating either the hook or the mounting member relative to the other so that the mounting member rotates to a position adjacent to the hook tip.

[0007] The receiving portion may have a groove for movement of the shaft portion having the rotating portion fixed to a tip end thereof. The main body portion of the mounting member may include a rod portion, a first arc-shaped portion extending in an arc from a first end of the rod portion toward the connecting portion, and a second arc-shaped portion extending in an arc from a second end of the rod portion toward the connecting portion.

[0008] In some embodiments, the length of the groove is set so that when either the hook or the attachment member is rotated relative to the other such that the attachment member is rotated to a position adjacent to the hook tip while the hook and attachment member are positioned on the same plane, (a) the attachment member can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening or an imaginary line set at a position corresponding to the minimum opening width of the hook opening, and / or (b) one of the first and second arcuate portions can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening, or the bar portion can be oriented parallel to the second and third imaginary lines.

[0009] In some embodiments, the hook base and connecting portion are configured such that when either the hook or the attachment member is rotated relative to the other such that the attachment member is rotated to a position adjacent to the hook tip while the hook and attachment member are disposed in the same plane, (a) one of the first and second arcuate portions can cross an imaginary line established at a position corresponding to the maximum opening width of the hook opening, or (b) the bar portion can be oriented parallel to the second and third imaginary lines.

[0010] The hook may have a side that extends flat along the second imaginary line. The second imaginary line and the third imaginary line may be tangents to an imaginary perfect circle or ellipse that defines the curved manner of the outer surface of the hook. The hook may be rotatable relative to the attachment member such that the second imaginary line and the third imaginary line are oriented parallel to the side edges of the suspended object when the main body of the attachment member is attached to the suspended object.

[0011] In some embodiments, assuming that an imaginary perfect circle or ellipse is set to define the curved manner of the hook, the hook base and connecting portion are configured such that the attachment member can intersect the imaginary perfect circle or ellipse when either the hook or the attachment member is rotated relative to the other so that the attachment member rotates to a position adjacent to the hook tip while the hook and attachment member are disposed in the same plane.

[0012] The hook base may include a receiving portion and the coupling portion may include a pivot portion. The hook may be J-shaped and the body portion may be D-shaped. The hook base and coupling portion may be configured such that the attachment member is releasably positioned adjacent the hook tip.

[0013] The groove may have a narrow portion where the groove width is reduced so that the attachment member can be releasably positioned at a position adjacent to the hook tip. At least one protrusion may be provided on the outer peripheral surface of the shank that is capable of contacting a protrusion provided on the receiving portion for forming the narrow portion. The protrusion on the outer peripheral surface of the shank contacts the protrusion provided on the receiving portion for forming the narrow portion to notify the user that the attachment member has reached a position adjacent to the hook tip.

[0014] The receiving portion includes first and second opposing portions disposed opposite each other, and a groove for movement of the shaft portion having the rotating portion fixed to the tip end thereof can be formed by the space between the first and second opposing portions. One end of the groove on the hook tip end side can be shaped to be narrowed stepwise or continuously. Effect of the Invention

[0015] One aspect of the present disclosure can facilitate miniaturization of a hanging device when not being used to hang a suspended object. [Brief description of the drawings]

[0017] Various embodiments and features will be described below with reference to the drawings. Those skilled in the art can combine the embodiments and / or features without the need for excessive explanation, and can also understand the synergistic effects of such combinations. In principle, overlapping explanations between embodiments will be omitted. The reference drawings are primarily intended to describe the invention, and are simplified for the convenience of drawing. Each feature is not only effective for the hanging device disclosed in this application, but is understood as a universal feature that is also applicable to various other hanging devices not disclosed in this specification.

[0018] A non-limiting hanging device 1 according to the present disclosure is shown in FIG. 1. Hanging device 1 is a combination of hook 2 and mounting member 3 manufactured by injection molding of resin. Note that hook 2 and mounting member 3 can be molded simultaneously using a common injection molding device and a common mold device, and the assembly process of hook 2 and mounting member 3 is not essential. Of course, the two may be separately injection molded and combined to manufacture the hanging device. For convenience, the description may be given with reference to the up-down direction, left-right direction, and front-back direction shown in FIG. 1. The front-back direction may be alternatively called the thickness direction, and the up-down direction may be alternatively called the vertical direction.

[0019] As shown in Figs. 1 to 3, in the hook 2, the hook base 21 and the hook tip 22 are arranged so as to be spaced apart from each other to define the hook opening 25, and the hook extension 24 extends so as to form a hook recess 23 between the hook base 21 and the hook tip 22. In the state shown in Fig. 1 (see also Fig. 8), the hook extension 24 extends in a certain direction (diagonally upward to the right in Fig. 1) to move away from the hook base 21, and then extends with a predetermined curvature (the curvature of an imaginary perfect circle C1 (see Fig. 8) that defines the curved form of the outer surface 2b of the hook 2) (in Fig. 1, it extends from diagonally upward to the right to the left, extends to the left, and extends diagonally downward to the left). This gives the hook 2 an approximately J-shaped shape. The inner surface 2a and the outer surface 2b of the hook 2 also extend in a J-shape. The hook opening 25 is always open, but a closing member may be added to the hook 2 to close the hook opening 25.

[0020] The mounting member 3 has a main body 31 to which the object 9 to be suspended is to be attached, and a connecting portion 32 connected to the main body 31 for engagement with the hook base 21. The main body 31 is a D-shaped ring (i.e., a D-ring) and has a rod 5, a first arc-shaped portion 61 extending in an arc from a first end 51 of the rod 5 toward the connecting portion 32, and a second arc-shaped portion 62 extending in an arc from a second end 52 of the rod 5 toward the connecting portion 32, which define a flat closed space 38. The rod 5 extends in the left-right direction with a substantially constant cross-sectional shape (for example, a circular cross-section). The first arc-shaped portion 61 and the second arc-shaped portion 62 become thicker (front-to-back width in FIG. 1) as they extend upward from the rod 5, thereby strengthening the connection with the shaft portion 43 described below. The connecting portion 32 is a pillar portion protruding from the main body portion 31 (specifically, a pillar portion connecting a rotating portion 41 and an axis portion 43 described below), but is not necessarily limited to this. The connecting portion 32 extends upward from a connection point between the first arc-shaped portion 61 and the second arc-shaped portion 62.

[0021] For the engagement between the hook 2 and the mounting member 3, a rotating part 41 can be provided on one of the hook base 21 and the connecting part 32, and a receiving part 42 for receiving the rotating part 41 can be provided on the other of the hook base 21 and the connecting part 32. The rotating part 41 is received and held by the receiving part 42 (e.g., loosely fitted), whereby the mounting member 3 and the hook 2 are engaged to be capable of rotating relative to one another.

[0022] The rotating part 41 is appropriately shaped for its smooth rotation, for example (i) shaped to have a smoothly curved surface on at least a part of its outer surface, or (ii) shaped as a polyhedron having three or more faces. The edges between adjacent faces of the polyhedron may be chamfered. In some cases, the rotating part 41 is formed with two separate parting lines corresponding to the boundary of the mold device (for example, the boundary between the slide cores), which confirms that the hook 2 and the mounting member 3 are simultaneously injection molded by a common mold device. The rotating part 41 is fixed to and supported by the tip of the shaft part 43. The shaft part 43 is rotatable in response to the rotation of the rotating part 41. The shaft part 43 has, for example, a circular cross section, but is not limited thereto.

[0023] The hook 2 and the mounting member 3 can be arranged on the same plane (a plane that is perpendicular to the rotation axis AX1 and includes the rotation axis AX2) (see FIG. 2). In this plane, the hook 2 can rotate around the rotation axis AX1 (parallel to the thickness direction of the hook 2) relative to the mounting member 3, and vice versa. The hook 2 can also rotate around the rotation axis AX2 (perpendicular to the thickness direction of the hook 2) relative to the mounting member 3, and the hook 2 and the mounting member 3 can be arranged on different planes that are perpendicular to each other by rotating 90 degrees (see FIG. 3). Although not necessarily limited to this, the hook 2 can have two (or more) degrees of freedom of rotation relative to the mounting member 3, which improves the usability of the hanging device 1. Note that the same plane on which the hook 2 and the mounting member 3 are arranged is perpendicular to the thickness direction of the hook 2 and the thickness direction of the mounting member 3. That is, the plane is perpendicular to the thickness direction of the hook 2 and the thickness direction of the mounting member 3 when they are arranged so that the thickness directions of the hook 2 and the mounting member 3 are parallel to each other. The thickness direction can be understood to correspond to the front-to-rear direction with respect to the suspender 1 shown in FIG.

[0024] The connecting portion 32 of the mounting member 3 may be provided with a rotating portion 41, and the hook base 21 of the hook 2 may be provided with a receiving portion 42. In this case, the hook base 21 and the connecting portion 32 may be configured as follows. The hook base 21 (receiving portion 42) has first and second opposing portions 47, 48 arranged opposite each other. A portion (first portion) of the space between the first and second opposing portions 47, 48 functions as a receiving groove for receiving the rotating portion 41, and another portion (second portion) functions as a groove 46 for the movement of the shaft portion 43. Each opposing portion 47, 48 may be provided with through holes 47j, 48j for partially receiving the rotating portion 41. According to this configuration, a mold device for simultaneously injection-molding the hook 2 and the mounting member 3 in the same mold device may be appropriately constructed. The through holes 47j, 48j penetrate the opposing portions 47, 48 in the thickness direction of the opposing portions 47, 48. As an alternative to the through holes 47j, 48j of the opposing portions 47, 48, recesses for partially receiving the rotating portion 41 may be provided.

[0025] The rotation of the hook 2 relative to the mounting member 3 reduces the overall size of the hanging device 1 (see FIG. 4). The free rotation or pivoting of the hook 2 relative to the mounting member 3 improves the ease of use of the hanging device 1. In this regard, there is a demand to maintain the overall size of the hanging device 1 small when the hanging device 1 is not in use, and also a demand to inform the user who operates the hook 2 that the hook 2 has reached a predetermined position. From either or both of these viewpoints, in some cases, a mechanism is employed that holds the position of the hook 2 relative to the mounting member 3 simply or temporarily, i.e., releasably from that position. Specifically, a narrow portion 46j with a reduced groove width is provided in the groove 46 (see FIG. 5). This makes it possible to maintain the relative positional relationship between the hook 2 and the mounting member 3 in a certain state, or to inform the user that the position has been reached.

[0026] In FIG. 5, the narrow portion 46j is provided to position the attachment member 3 at a position adjacent to the hook tip 22. In order for the shaft portion 43 to pass through the narrow portion 46j, the hook 2 needs to be operated more consciously, which allows the hook 2 to be easily or temporarily held in a desired position, or notifies the user that the hook 2 has reached a desired position. The narrow portion 46j can be formed by arranging a pair of protrusions 87, 88 facing each other on the facing surfaces of the facing portions 47, 48, but it may also be formed with only one protrusion. Each of the protrusions 87, 88 may be a single wavy protrusion extending from the outer periphery of the facing surfaces of the facing portions 47, 48 toward the inside (e.g., through holes 47j, 48j). The narrow portion 46j divides the groove 46 into a first groove region 46p and a second groove region 46q. The shaft portion 43 may be rotatable about its axial direction when received in the first groove region 46p of the groove 46, thereby further increasing the degree of freedom of deformation of the hanging device 1. In this case, it is preferable that the cross-sectional area of ​​the first groove region 46p is made (slightly) larger than that of the shaft portion 43.

[0027] The groove 46 may have one end 46e that narrows stepwise or continuously on the hook tip 22 side (see FIG. 5), thereby suppressing the occurrence of cracks in the hook 2 (e.g., the opposing portions 47, 48) due to the force that the shank 43 exerts on the first and second opposing portions 47, 48. The shank 43 has a perfectly circular cross section, but is not limited to this cross-sectional shape. The shank 43 cannot enter the one end 46e of the groove 46, and the one end 46e of the groove 46 has a width that is less than the maximum diameter or width of the shank 43.

[0028] A non-limiting example of the use of the hanging device 1 will be described with reference to Figs. 6 and 7. The object to be hung 9 is, for example, a portable or travel-use expandable accessory case, but is not limited thereto, and may be various other objects (typically lightweight objects weighing 1 kg or less), such as a board with a mirror attached. When the hanging device 1 is attached to the object to be hung 9 as shown in Fig. 6, the object to be hung 9 can be hung from the pole 8 (via the hanging device 1) by hanging the hook 2 on the pole 8 or the like shown by the dashed line in Fig. 6. When it is not necessary to hang the object to be hung 9, the hanging device 1 can be stored in the object to be hung 9 as shown in Fig. 7.

[0029] When main body portion 31 is D-shaped, attachment band 92 can be inserted through the loop of main body portion 31 and sewn to fabric material 91 of hanging device 1 at both sides. In this manner, main body portion 31 of mounting member 3 is firmly attached to object to be hung 9. Main body portion 31 can take a first position (FIG. 6) in which it is laid down so as to straddle side edge 93 of object to be hung 9, and a second position (FIG. 7) in which it is laid down on the opposite side to the first position. The first position of main body portion 31 is suitable for deploying hook 2 from object to be hung 9. The second position of main body portion 31 is suitable for storing hook 2 in object to be hung 9.

[0030] The above-mentioned engagement between the pivoting portion 41 and the receiving portion 42 allows the hook 2 to pivot on the same plane relative to the mounting member 3 (see FIG. 6). By changing the main body 31 from the second position to the first position and pivoting the hook 2 clockwise, the hook 2 can be positioned away from the object 9 to be hung, and the hook 2 can be hung on the pole 8. Although it depends on the engagement state between the pivoting portion 41 and the receiving portion 42, the hook 2 can pivot relative to the mounting member 3 around the rotation axis AX2 in the state shown in FIG. 6.

[0031] According to the present disclosure, the size of the hanging device 1 is promoted when it is not suspended. For reference, when the hook 2 and the mounting member 3 are connected to each other by a chain, the hook 2 can move freely relative to the mounting member 3, but there is a problem in that the hook 2 moves freely even when the hanging device 1 is not used to suspend the object to be suspended 9. According to the present disclosure, compared to this case, it is possible to ensure the freedom of movement of the hook 2 when suspended and to reduce the size of the hanging device 1 when not suspended. A more specific description will be given below with reference to the remaining drawings.

[0032] FIG. 8 shows that a plurality of virtual lines are set with respect to the hook 2, and FIG. 9 shows that a virtual line is set on the mounting member 3. As shown in FIG. 8, it is assumed that a first virtual line L1 extending from the hook base 21 (for example, a rotation axis AX1 (see also FIG. 2) perpendicular to the arrangement surface of the hook 2 and the mounting member 3) toward the bottom point 26 of the hook recess 23 is expressed by a synthesis of a first vector V1 extending in the depth direction of the hook recess 23 and a second vector V2 extending perpendicular to the first vector V1 from the tip of the first vector V1 to the bottom point 26 of the hook recess 23. Note that, from the viewpoint of clarity, the bottom point 26 of the hook recess 23 is set at the intersection of a virtual line L8 obtained by translating virtual lines L4 and L5 set corresponding to the opening width of the hook opening 25 and the bottom surface of the hook recess 23, but it may be another position that can be said to be the bottom of the hook recess 23 sufficiently distant from the hook base 21. The virtual line L4 is set at a position corresponding to the maximum opening width of the hook opening 25. The imaginary line L5 is set at a position corresponding to the minimum opening width of the hook opening 25. The depth direction of the hook recess 23 is diagonally rightward in Fig. 1 and Fig. 8, but other directions may also be adopted.

[0033] Second and third virtual lines L2, L3 parallel to the first vector V1 can be set to sandwich the hook base 21 and the hook tip 22. The second virtual line L2 is set with respect to the hook base 21, and the third virtual line L3 is set with respect to the hook tip 22. The second virtual line L2 contacts the outer surface of the hook base 21, and the third virtual line L3 contacts the outer surface of the hook tip 22. The second and third virtual lines L2, L3 may be tangents to an imaginary perfect circle C1 that determines the curved mode of the outer surface 2b of the hook 2.

[0034] The hook 2 can have a side surface 29 that extends flat along the second imaginary line L2. The hook recess 23 also has a width that increases and then decreases with distance from the hook opening 25 as represented by imaginary lines L5-L7 parallel to the imaginary lines L4, L5. This is also a consequence of the J-shaped extension of the inner side surface 2a of the hook 2. With respect to the mounting member 3, an imaginary line L9 can be assigned to the extension direction of the rod portion 5 as shown in FIG. 9.

[0035] With hook 2 and mounting member 3 arranged on the same plane, either hook 2 or mounting member 3 can rotate relative to the other such that mounting member 3 rotates from a position spaced apart from hook tip 22 (see FIG. 10) via an intermediate position (see FIG. 11) to an adjacent position (see FIG. 12). During this entire process, mounting member 3 does not cross third imaginary line L3. This facilitates miniaturization of hanging device 1, particularly when not being used to suspend object 9 to be hung.

[0036] In the separated position (FIG. 10), the hook base 21 is sandwiched between the mounting member 3 and the hook tip 22. In the intermediate position (FIG. 11), the hook base 21 is not sandwiched between the mounting member 3 and the hook tip 22. In the adjacent position (FIG. 12), the mounting member 3 is disposed at a position closer to the hook tip 22 compared to the separated and intermediate positions described above.

[0037] The fact that the mounting member 3 does not intersect the third imaginary line L3 means that the hook 2 does not intersect the side edge 93 when the hook 2 is rotated from the broken line position to the solid line position in Fig. 7. When an element of a slide fastener (e.g., a coil element, a metal element or a resin element, or a ceramic element) is disposed on the side edge 93, interference between the element and the hook 2 is avoided.

[0038] 12, mounting member 3 is capable of crossing fourth virtual line L4 set at a position corresponding to the maximum opening width of hook opening 25. Additionally or alternatively, mounting member 3 is capable of crossing fifth virtual line L5 set at a position corresponding to the minimum opening width of hook opening 25. That is, hook base 21 and connecting portion 32 are configured so that hanging device 1 can be in this state. This facilitates miniaturization of hanging device 1 when not being used to hang object 9 to be hung.

[0039] In addition, the length of groove 46 can also be described as being set so that mounting member 3 can cross the fourth or fifth virtual line L4, L5 when either hook 2 or mounting member 3 is rotated relative to the other so that mounting member 3 rotates toward hook tip portion 22 with the hook 2 and mounting member 3 arranged on the same plane.

[0040] One of the first and second arc-shaped portions 61, 62 may be able to cross the fourth or fifth imaginary line L4, L5 set at a position corresponding to the maximum or minimum opening width of the hook opening 25. Additionally or alternatively, the rod portion 5 may be able to be oriented parallel to the second and third imaginary lines L2, L3. That is, the hook base 21 and the connecting portion 32 are configured, or the length of the groove 46 is set, so that the hanging device 1 can be in this state. This facilitates the miniaturization of the hanging device 1 when it is not being used to hang the object 9 to be hung.

[0041] As can be seen from Fig. 13, the mounting member 3 can enter the hook opening 25 (or the hook recess 23 via the hook opening 25) from the first arc-shaped portion 61 or the second arc-shaped portion 62. When the hook 2 and the mounting member 3 are arranged on different planes that are perpendicular to each other (see Fig. 3), the entire mounting member 3 can pass through the hook opening 25 and enter the hook recess 23. In other words, the entire mounting member 3 can be arranged on the hook recess 23 side of the imaginary line L4.

[0042] The mounting member 3 is simply positioned and held in the position shown in Fig. 14. This is a result of the shaft portion 43 passing through the narrow portion 46j as described above (also see Fig. 15).

[0043] 16, assuming that an imaginary perfect circle C2 is set that determines the curved state of the inner surface 2a of the hook 2, the mounting member 3 (e.g., the first arc-shaped portion 61 or the second arc-shaped portion 62) can intersect with the imaginary perfect circle C2. That is, the hook base 21 and the connecting portion 32 are configured, or the length of the groove 46 is set, so that the hanging device 1 can be in this state.

[0044] Just to be clear, as is clear from Fig. 7, in a state in which the main body 31 of the mounting member 3 is attached to the suspended object 9, the hook 2 can rotate with respect to the mounting member 3 so that the second and third imaginary lines L2, L3 are oriented parallel to the linearly extending side edge 93 of the suspended object 9. Note that the side edge 93 is in a position to be straddled by the hook 2, and the mounting member 3 can be positioned thereon as an option.

[0045] 17 and 18 show an embodiment in which the shape of the hook 2 is not a perfect circle but is approximating an ellipse. Even in such a case, the same effects as those described above can be obtained as long as they are not inconsistent with the above description.

[0046] 17, a virtual ellipse C3 is illustrated as a substitute for the virtual perfect circle C1. A first virtual line L1 extending from the hook base 21 (rotation axis AX1) toward the bottom point 26 of the hook recess 23 is represented by a combination of a first vector V1 extending in the depth direction of the hook recess 23 and a second vector V2 extending from the tip of the first vector V1 to the bottom point 26 of the hook recess 23, perpendicular to the first vector V1.

[0047] In Fig. 18, a virtual ellipse C4 is illustrated as an alternative to the virtual perfect circle C2, and the mounting member 3 can intersect with the virtual ellipse C4. As shown in Figs. 17 and 18, the shape of the hook 2 can be changed without departing from the spirit of the present disclosure. Similarly, the mounting member 3 can be changed to another shape. To avoid redundant description, further description with reference to Figs. 17 and 18 will be omitted.

[0048] In FIG. 19, the outer peripheral surface of the shaft portion 43 of the mounting member 3 is provided with a protrusion 49 that can come into contact with the protrusions 87, 88 provided on the receiving portion 42 of the hook base 21 to form the narrow width portion 46j. The protrusion 49 is provided to protrude radially outward from the shaft portion 43. As a result, the shaft portion 43 is provided with small diameter portions 71, 72 and a large diameter portion 73. The large diameter portion 73 is a portion formed by providing the above-mentioned protrusion 49 on the outer peripheral surface of the shaft portion 43, and is provided between the small diameter portions 71, 72. The diameter of the large diameter portion 73 is, for example, within a range of 1.05 to 1.4 times the diameter of the small diameter portions 71, 72. In FIG. 19, the large diameter portion 73 is provided as a protrusion protruding radially outward, but this is not limited thereto, and one of the small diameter portions 71 in FIG. 19 may be formed to have the same diameter as the large diameter portion 73. In other words, one of the two small diameter portions 71, 72 can be omitted.

[0049] As shown in FIG. 20, when the shaft portion 43 is inserted into the narrow width portion 46j of the groove 46, the protrusion 49 (and the large diameter portion 73) of the shaft portion 43 comes into contact with the protrusions 87, 88 provided on the opposing portions 47, 48 to form the narrow width portion 46j in the groove 46 (note that only one protrusion may be provided for the narrow width portion 46j instead of two protrusions). When the protrusion 49 (and the large diameter portion 73) of the shaft portion 43 passes over the protrusions 87, 88, the force required to rotate the mounting member 3 increases instantaneously, so that the user can be informed that the mounting member 3 has reached a predetermined position (for example, the above-mentioned first groove region 46p). When the protrusion 49 (and the large diameter portion 73) is provided on the shaft portion 43 in this way, the function of informing the user can be maintained even if the remaining portion of the shaft portion 43 is reduced in diameter (narrowed). Note that it is preferable to make the first groove region 46p (slightly) larger than the cross-sectional area of ​​the large diameter portion 73.

[0050] A wall 81 may be provided on the opposing surface of each of the opposing parts 47, 48 so as to partially or entirely surround the open end of the through hole 47j, 48j, and the above-mentioned protrusions 87, 88 may be connected to this wall 81 (see FIG. 21). This prevents the portion of the slide core for molding the protrusions 87, 88 from being damaged due to collision with another slide core. Although not clearly shown in FIG. 21, the protrusion 87 is also provided on the opposing surface of the opposing part 47 so as to be connected to a wall (not shown) surrounding the open end of the through hole 47j. The wall 81 is a C- or U-shaped portion with an opening facing the opposite side to the above-mentioned first vector V1, but should not be limited thereto.
