Preferred embodiments of the present invention will be described below with reference to the drawings.
As shown in FIGS. 7 and 8, the accessory 100 with a length adjusting function of the accessory 100 according to the present invention includes a first fastener 101 and a second fastener 102 having the same configuration, and is 90 degrees with respect to the horizontal axis. Rotate to join both.

Since the first fastener 101 and the second fastener 102 have the same configuration,
Hereinafter, the configuration of the first fastener 101 will be described in detail.
As shown in FIG. 1, the first fastener 101 has a pair of decorative plates 10 and 11. The decorative plates 10 and 11 are formed, for example, curved outward in an arch shape, and holes 12 are formed in the frame so as to form a mesh pattern. The pattern formed on the decorative plates 10 and 11 varies depending on the position and size of the hole 12.

  For example, the size and arrangement of the pearl necklace pearls themselves can be changed. However, since one pearl constituting the pearls has a spherical shape, it is difficult to produce variability as an accessory. For this reason, the fastener at the end of the pearl necklace is an important design element for giving the whole change.

  Therefore, how to design the decorative plates 10 and 11 in a fashionable manner is a point that determines the marketability of the pearl necklace.

One of the decorative plates 10 and 11 (the right rear end in FIGS. 1 and 2) is provided with a hinge portion 14 that is biased by the spring force of the coil spring 13 in FIG.
The hinge portion 14 is a combination of support portions 15a and 15b projecting on the inner surfaces facing the end portions of the decorative plates 10 and 11, and is supported by a shaft 16. The decorative plates 10 and 11 swing around the shaft 16 as a fulcrum. It can be configured.
