AI Technical Summary

Technical Problem

Existing connectors are insufficient in terms of strength and torsional strength improvement. In particular, the shaft support at the base end of the opening and closing body is located in the shaft hole of the base body, which causes load concentration and makes it difficult to improve the overall strength.

Method used

A connector is designed, comprising a main body, an opening/closing part, and an elastic deformation part. By inserting the connector into the other end of the main body and hooking the second hooked part in the closed position, combined with the design of the elastic deformation part, stable hooking and movement of the opening/closing part are achieved, thereby enhancing the overall strength.

Benefits of technology

The strength and torsional stability of the connecting parts have been improved, especially at the connection between the opening/closing part and the main body, which enhances the resistance to disassembly and torsion, while allowing flexible opening and closing movement.

[0021] [Structure of this embodiment]

[0022] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0023] exist Figures 1 to 3 In this embodiment, the connecting member 1 is configured as a circular resin hook that connects to an article or connects separate articles or parts thereof. The connecting member 1 is integrally formed from resin material into a single component, comprising: a main body 2, which forms a storage space 10 through which a part such as a rope of the article being connected (not shown) passes, and is divided by one end 21 and the other end 22 into an opening 11 communicating with the storage space 10; an opening / closing part 3, which opens and closes the opening 11; and an elastically deformable part 4, which connects the main body 2 and the opening / closing part 3 in a manner that allows the opening / closing part 3 to move open and close. The opening / closing part 3 can be positioned at the open-closed position P1 (see reference 1) by its opening / closing movement. Figure 4 ) and the opening position P2 of opening 11 (refer to Figure 5 Furthermore, in this embodiment, the opening closed position P1 is the position of the opening / closing part 3 along the circumferential direction of the connecting member 1, and the opening open position P2 is the position where the opening / closing part 3 enters the storage space 10 from the opening closed position P1.

[0024] In the following description, the left-right direction of the link member 1 is set as the X-axis direction, the front-rear direction (width direction) of the link member 1 is set as the Y-axis direction, and the up-down direction of the link member 1 is set as the Z-axis direction. The X, Y, and Z-axis directions are orthogonal to each other. In addition, the opening-closing direction is set as the A direction, the opening direction is set as the Al direction, and the closing direction is set as the A2 direction. The facing direction of the front end portion 31 of the opening-closing portion 3 and the one end portion 21 of the main body portion 2 in the closed state is set as the B direction (also the circumferential direction of the link member 1 in this embodiment). Furthermore, the above-described directions are directions set for convenience in the description of this embodiment, and the link member 1 in the actual use state can be appropriately arranged in each orientation.

[0025] The main body portion 2 is formed in a hook shape, and in this embodiment, is formed in a C shape so as to hook a linked body, with the inner circumferential surface thereof dividing the accommodation space 10. In this embodiment, the position on the one side in the X-axis direction from the center of the circular arc of the main body portion 2 is set as the inner side of the accommodation space 10, and the position on the other side in the X-axis direction from the center of the circular arc of the main body portion 2 is set as the front side. The opening 11 is arranged at the position on the other side in the X-axis direction.

[0026] The one end portion 21 and the other end portion 22 of the main body portion 2 are arranged facing each other in the circumferential direction of the link member 1 with the opening 11 therebetween. In addition, the main body portion 2 has an extension portion 23 that is arranged extending in the circumferential direction from the connection position with the elastically deformable portion 4 toward the opening 11 side, and the other end portion 22 is constituted by the front end portion of the extension portion 23. The dimension of the extension portion 23 in the radial direction of the link member 1 is larger than the above-described dimension in the radial direction of the elastically deformable portion 4 and is smaller than the dimension in the radial direction of the portion of the main body portion 2 other than the above-described extension portion 23.

[0027] The first hooking portion 211 is formed at the one end portion 21, and is capable of releasable hooking to the first hooked portion 311 of the opening-closing portion 3 in the A2 direction. The width dimension of the first hooking portion 211 in the Y-axis direction is set to a smaller dimension than the portion continuous with the first hooking portion 211. The first hooking portion 211 has an inner surface 211A that abuts against the first hooked portion 311 in the A2 direction, and in addition, has a hook-shaped engaging portion 213 at the front end. The engaging portion 213 is capable of releasable engagement with the hook-shaped engaging portion 313 of the opening-closing portion 3.

[0028] The second hooking portion 221 is formed at the other end portion 22, and is capable of releasable hooking to the second hooked portion 323 of the opening-closing portion 3 in the A2 direction. The width dimension of the second hooking portion 221 in the Y-axis direction is set to a smaller dimension than the portion continuous with the second hooking portion 221. As shown in Figs. 1, 2, and 3, the second hooking portion 221 is in a hook needle shape, and as shown in Figs. 4 and 5, the second hooking portion 221 is in a hook needle shape. Figure 1 Figure 4 As shown in Figs. 1, 2, and 3, the second hooking portion 221 is in a hook needle shape, and as shown in Figs. 4 and 5, the second hooking portion 221 is in a hook needle shape. Figure 1 ​、 Figure 2 As shown in FIG. 1, a step portion 222 is formed protruding toward the Y-axis direction in a portion (a middle portion in the length direction of the extension portion 23) that is continuous with the base end portion of the second hooking portion 221. Therefore, the dimension of the extension portion 23 in the Y-axis direction is larger at a position on the base end side than at a position on the tip end side of the step portion 222. The step portion 222 is configured to abut against a portion of the insertion link portion 321 described later in the closing portion 3 on the insertion side. A locking protrusion 223 protruding toward the inside as the storage space 10 side and a protrusion 224 protruding toward the outside as the opposite side of the inside are formed in the tip end portion of the second hooking portion 221. A recess portion 221B recessed toward the inside in a manner that deviates from the movement trajectory of the abutment portion 324 described later is formed in a portion of the outer surface 221A of the second hooking portion 221 that is continuous with the protrusion 224. By forming the recess portion 221B in this manner, it is possible to position the position at which the abutment portion 324 abuts against the outer surface 221A when the closing portion 3 moves in the A1 direction to open at a position that is deeper into the storage space 10, and it is possible to expand the opening and closing movement region of the closing portion 3.

[0029] The closing portion 3 is formed in a circular arc shape and cooperates with the main body portion 2 to constitute a link member 1 in a circular ring shape in a state in which the opening is closed. The tip end portion 31 of the closing portion 3 is disposed facing the one end portion 21 of the main body portion 2 in the B direction in a state in which the opening is closed, and the base end portion 32 of the closing portion 3 is connected to the elastically deformable portion 4 at a portion on the outer peripheral side.

[0030] The tip end portion 31 has a first hooked portion 311 that hooks to the one end portion 21 of the main body portion 2 in the A2 direction in the closed position P1 and releases the hooked state in the A1 direction movement (opening movement).

[0031] The first hooked portion 311 has an abutment plate portion 312 that is formed in a portion on the inner peripheral side (inside) of the tip end portion 31 and can abut against the inner surface 211A of the first hooking portion 211 in the closed position P1, and a hook-shaped engagement portion 313 that is formed continuously with the tip end of the abutment plate portion 312. The outer surface of the abutment plate portion 312 abuts against the inner surface 211A, and by this abutment, the first hooked portion 311 becomes in a state of hooking to the first hooking portion 211 in the A2 direction. The engagement portion 313 is disengageably engaged with the engagement portion 213 of the first hooking portion 211 in the closed position P1, and by this engagement, the closed state of the closing opening 11 is stabilized. In addition, the first hooked portion 311 has a pair of side plate portions 314 that are formed continuously with the abutment plate portion 312, and by the abutment plate portion 312 and the pair of side plate portions 314, a groove portion 315 that can be configured to pull out the first hooking portion 211 is formed.

[0032] The base end portion 32 has an insertion link portion 321 into which the other end portion 22 of the main body portion 2 is inserted in a manner that allows the opening and closing movement of the opening and closing portion 3 in the A direction.

[0033] The insertion link portion 321 has a disposition hole portion 320 that is open on the inner side as the side of the accommodation space 10 and in which the other end portion 22 of the main body portion 2 is disposed in a manner that allows the opening and closing movement of the opening and closing portion 3. The second hooked portion 323 is disposed in the disposition hole portion 320. In the present embodiment, the disposition hole portion 320 is formed by a through hole 322 that penetrates from the inner side as the side of the accommodation space 10 to the outer side as the opposite side, and the second hooked portion 323 is formed in the portion of the through hole 322 on the inner peripheral side of the link member 1 in a manner that hooks the other end portion 22 of the main body portion 2 at the opening closed position PI and protrudes from the inner wall 322A that forms the through hole 322, and a hooked and fitted protrusion 323A that protrudes from the inner side as the side of the accommodation space 10 to the outer side as the opposite side is formed at the tip of the second hooked portion 323. In addition, the portion of the inner wall 322A of the insertion link portion 321 between which the second hooked portion 223 is disposed is provided as an abutting portion 324 that abuts against the outer surface 221A of the second hooked portion 221 at the opening open position P2. The link member 1 restricts the opening and closing portion 3 from moving open in the Al direction beyond the opening open position P2 by causing the abutting portion 324 to abut against the outer surface 221A. Further, the interval between the second hooked portion 221 and the abutting portion 324 is set to an interval that is wide enough to form a gap 325 between the second hooked portion 221, and by forming the gap 325, the opening and closing portion 3 is allowed to swing by an amount corresponding to the gap 325. Thus, the opening and closing movement of the opening and closing portion 3 in the A direction is made smooth.

[0034] The second hooked portion 323 is hooked to the second hooked portion 221 in the A2 direction and releases the hooked state in the Al direction movement (open movement) by being fitted with the hooked and fitted protrusion 223 at the opening closed position PI.

[0035] The elastic deformation portion 4 is integrally formed with the main body portion 2, has a standing portion 41 that protrudes outward (radially outward of the link member 1) from the main body portion 2 in a manner to be away from the accommodation space 10, and a continuous portion 42 that extends in a curved shape from a front end of the standing portion 41 toward the opening and closing portion 3 side, and is disposed in a position on the other side in the X-axis direction. The elastic deformation portion 4 is disposed apart from the extension portion 23 by a certain space, and ensures an elastic deformation space of the elastic deformation portion 4. The elastic deformation portion 4 always exerts a force on the opening and closing portion 3 in the A2 direction at the opening closing position PI, and, by elastic deformation thereof, holds the opening and closing portion 3 so as to be slightly swingable in the B direction.

[0036] With the above-described link member 1, Figure 1 The state shown is an initial state. The opening and closing portion 3 is disposed in a position outward of the opening 11, and the elastic deformation portion 4 is formed to have a smaller curvature than the main body portion 2.

[0037] Figure 1 The link member 1 shown is assembled by inserting the second hook portion 221 into the through hole 322 and disposing the first hooked portion 311 to a position on the accommodation space 10 side of the first hook portion 211. In Figures 2 to 4 The link member 1 shown is assembled by inserting the second hook portion 221 into the through hole 322 and disposing the first hooked portion 311 to a position on the accommodation space 10 side of the first hook portion 211. In

[0038] The opening and closing of the opening 11 in the above-described link member 1 is performed in the following manner.

[0039] (Opening operation)

[0040] With the link member 1 in which the opening and closing portion 3 is disposed at the opening closing position PI in the closed state (fully closed state), the engagement of the hook-shaped engagement portions 213, 313 is released. Specifically, by slightly flexing the main body portion 2 toward the accommodation space 10 side, or by bringing the opening and closing portion 3 held by the elastic deformation portion 4 so as to be slightly swingable in the B direction toward the one end portion 21 of the main body portion 2, the engagement of the hook-shaped engagement portions 213, 313 is released. Thus, the opening and closing portion 3 becomes in a state in which it is movable in the Al direction. Next, by operating the opening and closing portion 3, the opening and closing portion 3 is moved in the Al direction against the force of the elastic deformation portion 4, and thus the opening 11 is opened.

[0041] Then, when the opening and closing portion 3 is further moved in the Al direction and is disposed at Figure 5When the opening is opened at the opening open position P2, the abutting portion 324 of the opening and closing portion 3 abuts against the outer surface 221A of the second hooking portion 221 of the main body portion 2, and the base end portion 32 of the opening and closing portion 3 abuts against the step portion 222 of the main body portion 2, thereby restricting the opening and closing portion 3 from being moved in the Al direction beyond the opening open position P2. Thus, the opening and closing portion 3 is in an open state (full open state) in a state where it is disposed at the opening open position P2 without colliding with the inner side portion (inner peripheral portion) of the main body portion 2. By being in the open state in this way, it is possible to put a portion such as a rope of an article to be linked from the opening 11 into the storage space 10, and it is possible to link the link member 1 with the article, or link the articles with each other, or link portions of the article with each other. In addition, the opening and closing portion 3 is movable in the A direction between the opening closed position PI and the opening open position P2.

[0042] (Closing operation)

[0043] When the opening and closing portion 3 is stopped from being moved in the opening operation, the opening and closing portion 3 is moved in the A2 direction due to the urging force of the elastic deformation portion 4. Next, the first hooking portion 211 of the main body portion 2 is disposed in the groove portion 315 in the front end portion 31 of the opening and closing portion 3, the abutting plate portion 312 of the first hooked portion 311 is brought into a state of abutting against or capable of abutting against the inner surface 211A of the first hooking portion 211, and the hook-shaped engagement portion 313 is engaged with the hook-shaped engagement portion 213, thereby disposing the opening and closing portion 3 at the opening closed position PI and bringing it into a closed state. At this time, the second hooked portion 323 is hooked to the second hooking portion 221 by the engagement of the engagement protrusion 323A and the engagement protrusion 223. In this way, in the closed state, the second hooking portion 221 is in a state where the first hooked portion 311 is hooked to the first hooking portion 211 and the second hooked portion 323 is hooked to the second hooking portion 221 which is inserted into the through hole 322. Thus, for example, compared to a case where the base end portion of the opening and closing portion is supported by the main body portion in the A direction, in particular, it is possible to insert the second hooking portion 221 deeply into the insertion linking portion 321 and to hook the second hooked portion 323 of the above-described structure to the second hooking portion 221, and it is possible to improve the strength against the force in the A2 direction and the torsional force of the link member 1.

[0044] Here, the connector 1 is closed by hooking the first hooked part 311 to the first hooked part 211 and the second hooked part 323 to the second hooked part 221 at the closed position P1. However, each of the first hooked part 311 and the first hooked part 211, and the second hooked part 323 and the second hooked part 221, does not necessarily need to abut against each other, as long as they are in a hooked state. For example, even if a gap is formed between either the first hooked part 311 and the first hooked part 211, or between the second hooked part 323 and the second hooked part 221, as long as the first hooked part 311 and the first hooked part 211, and the second hooked part 323 and the second hooked part 221, have this gap forming, they can abut against each other to form a hooked state when force is applied in the A2 direction.

[0045] In addition, in this embodiment, the outer diameter profile of the elastic deformation part 4 is arranged along the outer diameter profile line (imaginary line) of the main body part 2 in the closed state, and the connecting member 1 presents a circular shape in cooperation with the main body part 2 and the opening and closing part 3.

[0046] Furthermore, in the open state of the connector 1, by moving the opening / closing part 3 in the direction of A1, the abutting plate part 312 moves away from the inner surface 211A of the first hook part 211, thereby releasing the hook between the first hooked part 311 and the first hook part 211, and the locking protrusion 323A disengages from the locking protrusion 223, thereby releasing the hook between the second hooked part 323 and the second hook part 221.

[0047] The above connector 1 is installed in bags, etc., and is used to hook various items or parts thereof.

[0048] [Variation Example]

[0049] In the above embodiment, the main body 2 is formed in the shape of a C, but it is not limited to this. As long as it is a shape that can hook onto the connected body, it can also be formed in other shapes such as the shape of a コ or the shape of a J.

[0050] In the above embodiment, the insertion connecting portion 321 has a through hole 322 for inserting a second hook portion 221 in the shape of a hook needle, which serves as a configuration hole 320 for the other end 22 of the opening / closing portion 3. In the open state, the front end of the second hook portion 221 protrudes outward from the through hole 322 (see reference). Figure 5 However, it is not limited to this. The insertion connector 321 can be configured to properly position the other end 22. For example, the insertion connector 321 can also be formed as a bottomed recessed portion for inserting the second hook portion 221 as a configuration hole portion 320. Alternatively, a small hole extending to the outside can be formed at the bottom of the aforementioned recessed portion.

[0051] In the above embodiment, the second hooked portion 323 is formed with the engaged protrusion 323A, and the first hooked portion 211 is formed with the engaging protrusion 223, and the engaged protrusion 323A and the engaging protrusion 223 are engaged in the closed state, but not limited thereto, and in the case where the second hooked portion 323 is in abutment with the first hooked portion 211 in the A2 direction even without the engagement, the structure of the engaged protrusion 323A and the engaging protrusion 223 can be omitted.

[0052] In the above embodiment, the abutment portion 324 of the insertion link portion 321 is in abutment with the outer surface 221A of the main body portion 2 at the opening opening position P2 to restrict the opening movement of the opening and closing portion 3, but not limited thereto, and for example, in the case where the opening and closing portion 3 is in abutment with other portions of the main body portion 2 at the opening opening position P2 to restrict the opening movement thereof, the abutment portion 324 can be set to a non-abutment state with respect to the outer surface 221A at the opening opening position P2.

[0053] In the above embodiment, the outer surface 221A of the main body portion 2 where the abutment portion 324 is in abutment is formed with the recessed portion 221B recessed from the movement track of the abutment portion 324, but not limited thereto, and in the case where the opening and closing movement region of the opening and closing portion 3 can be sufficiently obtained, the structure of the recessed portion 221B can be omitted.

[0054] In the above embodiment, the stepped portion 222 is formed to be in abutment with the portion of the insertion link portion 321 on the insertion side in the opening and closing portion 3 at the opening opening position P2, but not limited thereto, and in the case where the opening and closing portion 3 is in abutment with other portions at the opening opening position to restrict the opening movement thereof, the stepped portion 222 can be set to a non-abutment state with respect to the outer surface 221A at the opening opening position P2.

[0055] In the above embodiment, the front end of the second hooked portion 323 is in a non-abutment state with respect to the other end portion 22 of the main body portion 2 at the opening opening position P2, but not limited thereto, and in the case where the front end of the second hooked portion 323 is in abutment with the other end portion 22 of the main body portion 2 at the opening opening position P2 to restrict the opening movement of the opening and closing portion in the Al direction.

[0056] In the above embodiment, the link member 1 is configured as a carabiner, but in addition thereto, can be configured by a clasp or the like.

[0058] (1) The coupling member 1 of the present embodiment integrally has: a main body portion 2 that forms an accommodation space 10 for a body to be coupled to pass through and is divided by one end portion 21 and the other end portion 22 to communicate the accommodation space 10 with an opening 11; an opening and closing portion 3 that opens and closes the opening 11; and an elastically deformable portion 4 that connects the main body portion 2 and the opening and closing portion 3 in a manner that enables the opening and closing portion 3 to open and close, wherein the opening and closing portion 3 has: a first hooked portion 311 that hooks to the one end portion 21 of the main body portion 2 in the A2 direction at an opening-closing position P1 of the opening 11 and releases the hooked state in the A1 direction movement; and an insertion coupling portion 321 that enables the opening and closing movement of the opening and closing portion 3 in a manner that the other end portion 22 of the main body portion 2 is inserted, and a second hooked portion 323 is formed in the insertion coupling portion 321, the second hooked portion 323 hooks to the other end portion 22 of the main body portion 2 in the A2 direction at the opening-closing position P1 and releases the hooked state in the A1 direction movement.

[0059] According to the coupling member 1 of the present embodiment, by inserting the other end portion 22 of the main body portion 2 into the insertion coupling portion 321 of the opening and closing portion 3, the coupling state in which the opening and closing portion 3 is combined to the main body portion 2 so as to be able to open and close is achieved, and at the opening-closing position P1, the first hooked portion 311 of the opening and closing portion 3 hooks to the one end portion 21 of the main body portion 2 in the A2 direction and the second hooked portion 323 hooks to the other end portion 22 of the main body portion 2 in the A2 direction, so that, for example, compared with the case where the opening and closing portion 3 is axially supported to the main body portion 2, the improvement of the strength with respect to the direction in which the opening and closing portion 3 is detached to the outside of the coupling member 1 can be achieved. In addition, the other end portion 22 of the main body portion 2 in which the second hooked portion 323 is hooked is inserted into the insertion coupling portion 321, so that, for example, compared with the case where the opening and closing portion 3 is axially supported to the main body portion 2, the improvement of the strength of the coupling member 1 with respect to the twisting direction can be achieved. Furthermore, the other end portion 22 of the main body portion 2 is inserted into the insertion coupling portion 321 in a manner that enables the opening and closing movement of the opening and closing portion 3, so that, for example, compared with the case where the base end portion of the opening and closing portion is axially supported, the opening and closing movement of the opening and closing portion 3 can be achieved using the entire elastically deformable portion 4, the concentration of the load to only a part of the elastically deformable portion 4 can be suppressed, and the improvement of the strength of the coupling member 1 can be achieved.

[0060] Thus, according to the coupling member 1, the improvement of the strength can be achieved and the coupling state of the opening and closing portion 3 with respect to the main body portion 2 can be appropriately maintained.

[0061] (2) In the link member 1 of the present embodiment, the main body portion 2 is divided to form a hook shape with the opening 11, and a first hooking portion 211 that can be releasably hooked to the first hooked portion 311 in the A2 direction is formed at the one end portion 21 of the main body portion 2, and a second hooking portion 221 that can be releasably hooked to the second hooked portion 323 in the A2 direction is formed at the other end portion 22 of the main body portion 2.

[0062] According to such a structure, in a case where the opening and closing portion 3 is disposed at the opening closing position P1, the first hooked portion 311 and the second hooked portion 323 of the opening and closing portion 3 are hooked to the first hooking portion 211 and the second hooking portion 221 of the main body portion 2, thereby becoming a state in which the opening and closing portion 3 and the main body portion 2 are firmly linked, and it is possible to improve the strength of the link member 1 in the closed state, and in a case where the opening and closing portion 3 is disposed at a position that moves from the opening closing position P1 to be opened, the hooked state is released, and therefore, for example, compared to a case where the opening and closing portion 3 is supported by a shaft, it is possible to configure a structure in which a swing other than rotation is allowed in the opening and closing movement of the opening and closing portion 3.

[0063] (3) In the link member 1 of the present embodiment, the main body portion 2 has an extension portion 23 that is provided so as to extend from a connection position with the elastically deformable portion 4 toward the opening 11, the elastically deformable portion 4 extends along the extension portion 23 on the outside of the extension portion 23, and the other end portion 22 of the main body portion 2 is constituted by a front end portion of the extension portion 23.

[0064] According to such a structure, it is possible to form the elastically deformable portion 4 to be long in the link member 1 in which the main body portion 2 and the opening and closing portion 3 are integrally and continuously formed via the elastically deformable portion 4, and therefore, it is possible to expand the region in which the opening and closing portion 3 can swing. Therefore, it is possible to easily insert the other end portion 22 of the main body portion 2 into the insertion linking portion 321 of the opening and closing portion 3, and it is also possible to flexibly allow a swing other than rotation that occurs in conjunction with the opening and closing movement of the opening and closing portion 3, and it is possible to cause the opening and closing portion 3 to perform a smooth opening and closing movement.

[0065] (4) The insertion linking portion 321 has a disposition hole portion 320 that is open on the inside as the receiving space 10 side and that is disposed so as to allow the opening and closing movement of the opening and closing portion 3, and the other end portion 22 of the main body portion 2 is disposed in the disposition hole portion 320, and the second hooked portion 323 is disposed in the disposition hole portion 320.

[0066] According to such a structure, by inserting the other end portion 22 of the main body portion 2 into the insertion linking portion 321 from the inside and disposing it in the disposition hole portion 320, it is possible to appropriately link the opening and closing portion 3 and the main body portion 2.

[0067] (5) In the link member 1 of the present embodiment, the configuration hole portion 320 is formed by a through-hole 322 that penetrates from the inner side as the side of the accommodation space 10 to the outer side as the opposite side and into which the other end portion 22 of the main body portion 2 is inserted in a manner that allows opening and closing movement of the opening and closing portion 3,

[0068] The second hooked portion 323 is formed on the inner wall 322A that forms the through-hole 322 in a manner that hooks the other end portion 22 of the main body portion 2 at the opening closing position P1.

[0069] According to such a structure, by forming the through-hole 322 into which the other end portion 22 of the main body portion 2 is inserted in the insertion link portion 321, for example, compared to a case in which a recess portion into which the other end portion 22 of the main body portion 2 is inserted is formed in the insertion link portion 321, the opening and closing portion 3 can be formed to be small, and the complication of the shape and structure of a mold for shaping the opening and closing portion 3 can be avoided.

[0070] (6) In the link member 1 of the present embodiment, a locking protrusion portion 223 that protrudes toward the inner side as the side of the accommodation space 10 is formed on the other end portion 22 of the main body portion 2, and a hooked portion 323A that protrudes toward the outer side as the opposite side of the inner side and is locked by the locking protrusion portion 223 at the opening closing position P1 is formed on the second hooked portion 323.

[0071] According to such a structure, the hooked portion 323A and the locking protrusion portion 223 are locked at the opening closing position P1, and therefore, the strength in the direction in which the opening and closing portion 3 is detached to the outer side of the link member 1 can be increased, and the other end portion 22 of the main body portion 2 can be prevented from being unexpectedly pulled out of the insertion link portion 321 of the opening and closing portion 3.

[0072] (7) In the link member 1 of the present embodiment, the insertion link portion 321 has an abutting portion 324 that abuts against the outer surface 221A of the main body portion 2 at an opening opening position P2 at which the opening 11 is opened.

[0073] According to such a structure, the opening and closing portion 3 can be prevented from being excessively opened and moved beyond the opening opening position P2.

[0074] (8) In the link member 1 of the present embodiment, the outer surface 221A of the main body portion 2 that is abutted by the abutting portion 324 is formed with a recess portion 221B that is recessed in a manner that deviates from the movement locus of the abutting portion 324.

[0075] According to such a structure, the abutting portion 324 that moves when the opening and closing portion 3 is opened and closed can be avoided by the recessed portion 221B, and thus the position at which the abutting portion 324 abuts against the outer surface 221A can be located on the side of the accommodation space 10, and thus the opening and closing movement region of the opening and closing portion 3 can be enlarged.

[0076] (9) In the link 1 of the present embodiment, a step portion 222 that abuts against a portion on the insertion side of the insertion link portion 321 in the opening and closing portion 3 at an opening opening position P2 at which the opening 11 is opened is formed at the other end portion 22 of the main body portion 2.

[0077] According to such a structure, the opening and closing portion 3 can be inhibited from being excessively opened and moved beyond the opening opening position P2.
