Below, the spherical jewelry by this implementation is demonstrated based on drawing.
As shown in FIG. 1A, the spherical jewelry uses a pearl (sphere) 1 in this embodiment. Further, the pearl 1 is provided with an insertion hole 2, and the insertion hole 2 passes through the center of the pearl 1. Moreover, the penetration hole 2 of the pearl 1 is provided with the hollow 3 which continues over the perimeter of the outer peripheral part of the penetration hole 2 in two places spaced apart in the penetration direction like FIG.1 (b). The elastic holding member 4 is formed in a cylindrical shape using an elastic holding member as a material. Further, the pin 9 is inserted into the cylindrical hole 5 of the elastic holding member 4 so that it can be elastically held.

Next, the state when the elastic holding member 4 is press-fitted into the insertion hole 2 of the pearl (sphere) 1 will be described with reference to FIGS.
When the elastic holding member 4 is press-fitted into the insertion hole 2 of the pearl 1, a part of the elastic holding member 4 bites into the recess 3 provided in the outer peripheral portion of the insertion hole 2 by elastic recovery from compression at the time of press-fitting. As a result, the elastic holding member 4 is locked by the pressing force into the pearl 1 due to the elastic return from the compression after the press-fitting and a part of the elastic holding member 4 that has entered the recess 3.

The spherical jewelry according to the present embodiment formed as described above has the following functions and effects.
Only by providing the depression 3 only in a part of the insertion hole 2 of the pearl 1, a part of the elastic holding member 4 enters and is locked inside the pearl 1. Thereby, since the elastic holding member 4 can be fastened inside only by performing a minimum process in the inside of the pearl 1 other than the insertion hole 2, durability of the pearl 1 can be ensured. Furthermore, since a part of the elastic holding member 4 is locked in the recess in a tight state, the elastic holding member 4 is difficult to come out of the pearl 1, and the spherical shape according to the present embodiment as shown in FIGS. 3 (a) and 3 (b). When using the jewelry to which the jewelry is applied, when the pin 9 is inserted into the elastic holding member 4 press-fitted into the pearl insertion hole, the elastic holding member 4 is not unexpectedly detached from the insertion hole 2 of the pearl 1.

  As another embodiment of the present invention, as shown in FIG. 4A, a spiral groove portion 7 is provided on the outer peripheral portion of the insertion hole 2 of the sphere 1. Even if formed in this way, when the elastic holding member 4 is press-fitted into the insertion hole 2 of the sphere 1, the outer peripheral portion of the elastic holding member 4 enters the spiral groove 7, and a part of the elastic holding member 4 bites in. 4B and FIG. 4C, when each part of the elastic holding member 4 is engaged with the outer peripheral part of the insertion hole 2 of the sphere 1 and the accessory to which the spherical jewelry according to this embodiment is applied is used. In addition, even if the pin 9 is inserted and removed, the elastic holding member 4 is not easily pulled out from the insertion hole 2 of the sphere 1. Further, the sphere 1 may be one in which the inside is solid and integral like the pearl 1 described above, and another core material 11 may be placed inside the hollow sphere 1 as shown in FIG. In other words, the insertion hole 2 is formed in another core material 11 and the hollow 3 or the groove 7 is provided in the outer periphery of the insertion hole 2 so that the interior represented by the pearl 1 is a solid solid sphere 1. In the same manner as described above, the elastic holding member 4 cannot be pulled out from the insertion hole 2. Further, FIGS. 6A and 6B are applied to piercing as another embodiment of the present invention. This piercing uses a pearl 1 as a sphere 1, and an insertion hole 8 is provided to a position slightly deeper than the center of the pearl 1. Further, the recess 3 is provided on the outer peripheral portion of the insertion hole 8 and the elastic holding member 4 is press-fitted into the insertion hole 8, whereby the elastic holding member 4 is elastically restored from the pressed and compressed state. The part bites into the dent 3. Thereby, when the elastic holding member 4 is locked inside the pearl 1 and the pin 9 is inserted into the insertion hole 8, the elastic holding member 4 is not easily pulled out from the insertion hole 2 of the pearl 1.

  The spherical ornaments according to the present invention are those in which the hollow 3 is provided in a part of the outer peripheral portion of the insertion hole 2 or the insertion hole 8 of the spherical body 1 and the spiral groove portion 7 is provided in each of the above embodiments. Although described, within the scope of the claims described in the present application, the shape, size, depth, and the like of the recess 3 and the groove 7 can be freely changed.
