The urging member insertion hole 52 is formed so that the urging member 40 can be inserted in the Y direction. The connection hole 53 is provided at the end of the connection member 50 on the −X side. For example, the annular member 3 (see FIG. 8) connected to one end of the decorative portion 2 of the accessory 1 is inserted into the connection hole 53. Thereby, the fastener 100 and the decoration part 2 are connected via the connection member 50. Note that the connecting member 50 is not limited to the configuration described above. For example, the connection member 50 may be integrally formed on the surface of the first main body 10 or the second main body 20. Further, the connection member 50 may not be provided in the fastener 100.

The fastener 100 has a front insertion hole 60 that penetrates the front surface (the surface on the + X side) in the X direction as shown in FIGS. 1 and 4B while holding the gem P. The front insertion hole 60 is formed from the first front concave portion 17 and the second front concave portion 27. The shape of the front insertion hole 60 is a substantially circular shape centered on the central portion O of the gem P as viewed from the X direction. The front insertion hole 60 allows a part of the decorative portion 2 of the accessory 1 to be inserted in a direction (X direction) perpendicular to the support shaft 30 along the plane S. Thereby, as shown to Fig.4 (a), in the fastener 100, the 1st holding part 12 and the 2nd holding part 22 are arrange | positioned so that the gem P1 of the edge part of the decoration part 2 may be pinched | interposed, and relative Even if it closes and holds the gem P1, the part of the decorative part 2 including the connecting portion Pa between the gem P1 and the gem P2 adjacent to the gem P1 is inserted into the front insertion hole 60, It is avoided that the 1 grip part 12 or the 2nd grip part 22 and the decoration part 2 mutually cross and interfere. Therefore, by having the front insertion hole 60, the fastener 100 can grasp the gem P1 at the end of the decorative portion 2 from the −X side and connect the ends of the decorative portion 2 of the accessory 1 in a straight line. (See FIG. 8).

Moreover, the fastener 100 is the state which hold | gripped the gem P, as shown to FIG. 1, FIG. 4 (a), and the 1st holding part 12 in the direction (Z direction) parallel to the spindle 30 along the plane S. And the side insertion hole 70 which penetrates the 2nd holding part 22 is provided. The side surface insertion holes 70 are formed on both side surfaces of the fastener 100 on the + Z side and the −Z side, respectively. The two side surface insertion holes 70, 70 are formed in a substantially circular shape centering on the central portion O of the gem P, as viewed from the Z direction, so that they overlap each other. The side surface insertion hole 70 is formed by the first side surface recess 18 and the second side surface recess 28. In the side surface insertion hole 70, a part of the accessory 1 including the gem P can be inserted in a direction parallel to the support shaft 30 along the plane S. Therefore, in the fastener 100, even if the 1st holding part 12 and the 2nd holding part 22 are arrange | positioned so that the gem P may be pinched | interposed and it may close relatively and hold the gem P, it will adjoin the held gem P Since a part of the decoration part 2 including the connection part Pb with the gem P2 is inserted into the side surface insertion hole 70, interference between the first holding part 12 or the second holding part 22 and the decoration part 2 occurs. Avoided.

Next, the operation of the fastener 100 when gripping the gem P will be described. First, the user simultaneously presses the first protrusion 13 of the fastener 100 in the −Y direction and the second protrusion 23 in the + Y direction simultaneously with a finger so as to oppose the urging force of the urging member 40. Then, as shown in FIG. 5A, the first main body 10 and the second main body 20 rotate around the support shaft 30, and the first grip 12 and the second grip 22 are relative to each other. It will be in the open state.

Next, as shown in FIG. 5B, the user maintains the first protrusion 13 and the second protrusion so that the first grip 12 and the second grip 22 are kept relatively open. While pressing 23 in the direction of the arrow in FIG. 5B, the first gripping portion 12 and the second gripping portion 22 are arranged at positions where the gem P is sandwiched.

Subsequently, with respect to the fastener 100 in a state in which the first gripping portion 12 and the second gripping portion 22 are relatively open and are arranged with the gem P interposed therebetween, the user can 2 Press against the protrusion 23 is loosened. Then, the urging force of the urging member 40 acts and the first main body portion 10 and the second main body portion 20 rotate, and the first holding portion so as to sandwich the gem P as shown in FIG. 12 and the 2nd holding part 22 close relatively. Thereby, the gem P is held by the fastener 100.

On the other hand, when the gemstone P gripped in this way is removed from the fastener 100, the user firstly, as in the case where the fastener 100 grips the gemstone P, the first protrusion 13 and the first projection of the fastener 100. 2 The protrusions 23 are simultaneously pressed with a finger so that the first holding part 12 and the second holding part 22 are relatively opened. Next, the gem P is detached from the fastener 100 in this state. As a result, the connection between the fastener 100 and the gem P by grasping the fastener 100 is released.

As described above, according to the fastener 100, the first gripping portion 12 and the second gripping portion 22 are relatively opened only by pressing the first projecting portion 13 and the second projecting portion 23 at the same time, and further pressing is performed. By loosening, the 1st holding part 12 and the 2nd holding part 22 can be closed relatively. Therefore, the operation of the fastener 100 when gripping the gem P and when removing the gem P can be easily and reliably performed.

Moreover, since the fastener 100 is provided with the 1st opening part 14 and the 2nd opening part 24, it can be hold | gripped in the state in which the gem P was inserted. Moreover, since the fastener 100 has the 1st holding part 12 with which the front-end | tip part 15 cross | intersected with respect to the plane S, the force of the direction parallel to the plane S and away from the spindle 30 acts with respect to the gem P Even so, the gem P is only pressed against the surface on the −X side of the tip portion 15 of the first gripping portion 12, and the first gripping portion 12 and the second gripping portion 22 are prevented from opening relatively. Is done. Therefore, according to the fastener 100, the gem P can be stably and reliably gripped, and the gem P can be prevented from being carelessly detached from the fastener 100.

In addition, the fastener 100 has the front insertion hole 60 and the side insertion hole 70, so that it is possible to hold both the gem P1 at the end of the decorative portion 2 of the accessory 1 and the gem P2 at the intermediate portion. Therefore, as a form of connection between the decorative portions 2 by the fastener 100, for example, in addition to connecting in a straight line through the front insertion hole 60, one end of the decorative portion 2 holding the gem P1 is grasped. It is also possible to connect in an L shape via the side insertion hole 70, or to hold the gem P2 in the middle part of the decorative portion 2 and connect it in a Y shape via both side insertion holes 70, 70. . Therefore, according to the fastener 100, the accessory 1 can be formed, for example in the shape which has cyclic | annular form or a substantially Y shape, etc., and the variation of the shape of the accessory 1 can be increased.

As mentioned above, although the fastener 100 of 1st Embodiment was demonstrated, the fastener 100 is not limited to an above-described structure. For example, the first grip 12 may not have one or both of the first front recess 17 and the first side recess 18. The second grip 22 may not have one or both of the second front recess 27 and the second side recess 28. The side surface insertion hole 70 in the case where the first side surface recess 18 and the second side surface recess 28 are not provided may be formed in a slit shape generated between the first grip portion 12 and the second grip portion 22. Moreover, in the fastener 100 in the state of gripping the gem P, the tip portion 25 of the second grip portion 22 may be provided so as to contact or intersect the plane S, and the tip of the second grip portion 22 26 may be formed so as not to come into contact with the tip 16 of the first grip portion 12.
