That is, the region of the spring 13 near the bent portion 65 is fixed to the first member 11 (or the movement is slightly restricted).

As shown in FIG. 1, the intermediate fixing member 15 is configured to be insertable into the receiving portion 55. An intermediate fixing member 15 is fitted in the receiving portion 55. The intermediate fixing member 15 is arranged so as to connect between the two facing portions 24. In one example, the intermediate fixing member 15 is firmly fixed by welding to the receiving portion 55. In another example, the intermediate fixing member 15 may be removably fixed to the receiving portion 55. As shown in FIG. 4, the intermediate fixing member 15 projects toward the outer peripheral portion 51 between the two facing portions 24. The outer peripheral portion 51 is provided with an intermediate protrusion 56 at a position facing the intermediate fixing member 15.

The movement of the spring 13 is restricted by the sandwiching of the spring 13. Therefore, during operation, the portion of the second spring region 64 between the intermediate fixing member 15 and the movable end portion 62 moves relatively large.

As shown in FIG. 4, the spring 13 applies a pressing force to the first contact portion 41 to suppress the rotation of the second member 12 in the direction in which the gap 16 becomes larger at the closed rotation position. That is, the spring 13 presses the first contact portion 41 in the closed rotation position in the direction of reducing the gap 16. Further, the spring 13 applies a pressing force to the contact portion 40 to suppress the rotation of the second member 12 in the direction in which the gap 16 becomes larger in the first rotation range. The first rotation range is a part of the total rotation range between the closed rotation position and the open rotation position, and is a rotation range including the closed rotation position.

The spring 13 comes into contact with the contact portion 40 at a position sandwiched between the two facing portions 24 in the rotation range including the closed rotation position, which is at least a part of the rotation range of the first rotation range. As shown in FIG. 4, in a certain rotation range including the closed rotation position, the two facing portions 24 extend inward toward the inner space 17 beyond the spring 13. In the first rotation range, the spring 13 is configured to press the contact portion 40 in a state where the movable end portion 62 is separated from the second member 12 in the direction orthogonal to the rotation axis of the connecting portion 14. .. In another example, the movable end 62 may come into contact with the second member 12 in at least a portion of the first rotation range.

At a certain rotation position between the closed rotation position and the open rotation position, the distance between the virtual rotation axis of the connecting portion 14 and the spring 13 is maximized, so that the first rotation range and the second rotation range can be set. In order to change the state of the fitting 1 between them, it is necessary for the user to apply a certain amount of force against the pressing force of the spring 13.

While the accessory 1 is transitioning between the first rotation range and the second rotation range, the spring 13 comes into contact with the third contact portion 43. That is, when the accessory 1 transitions from the first rotation range to the second rotation range, the spring 13 contacts the first contact portion 41, the third contact portion 43, and the second contact portion 42 in order. When transitioning from the second rotation range to the first rotation range, the spring 13 contacts the second contact portion 42, the third contact portion 43, and the first contact portion 41 in order. As shown in FIG. 4, in the first rotation range in this example, the spring 13 has a ridge shape between the first contact portion 41 and the third contact portion 43 of the first contact portions 41.

As a result, it is possible to satisfactorily perform the pinching operation and the removing operation of an object (earlobe or the like) in the vicinity of the closed rotation position.
Further, since the two facing portions 24 have a function of rotatably sandwiching and supporting the protruding portion 34 and a function of supporting the rotation axis of the connecting portion 14, an independent member only for suppressing the shake of the spring is provided. The structure can be simplified as compared with the case of providing.

According to the present embodiment, the contact position between the spring 13 and the contact portion 40 is limited to the range sandwiched by the two facing portions 24 of the first rotating portion 22, so that the spring 13 and the contact portion 40 are in contact with each other. It becomes easy to suppress the blurring of the contact position.

According to the present embodiment, the gap 16 between the first mounting portion 21 and the second mounting portion 31 is prevented from becoming large in the first rotation range, and the first mounting portion 16 is prevented from becoming large in the second rotation range. It is possible to prevent the gap 16 between the portion 21 and the second mounting portion 31 from becoming smaller.

The elastic force of the spring 13 can be increased.
Further, since the intermediate fixing member 15 is inserted into the receiving portion 55 of the first member 11, the intermediate fixing member 15 is inserted into the receiving portion 55 after the spring 13 is attached to the first member 11. However, the intermediate fixing member 15 can be fixed to the first member 11 by a method such as welding. Therefore, the work of attaching the spring 13 to the first member 11 can be easily performed.
