2 is engaged with the holding member 13, and the accessory 11 is locked to the object T.

Further, in the present embodiment, as shown in FIG. 9, when the tip side portion 16B of the pin body 16 is housed in the pin body housing portion 18, the holding member 13 is held.
At least a part of the front surface of the above contacts the back surface of the base 14 of the accessory body 12 through the target T. Therefore, the accessory 11 is clamped by sandwiching the target T at the contact portion between the back surface of the base 14 and the front surface of the holding member 13. With the configuration in which the accessory main body 12 and the holding member 13 are engaged with each other in this manner, the accessory 11 can be reliably locked to the target T.
Further, since the pin body 6 is formed in a hook shape, the distal end side portion 16B of the pin body 16 is turned upward in its used state, so that the holding member 1 engaging with the pin body 16 is formed.
There is no problem such that 3 is separated from the accessory body 12. Further, since the pin body 16 is housed in the pin body housing portion 18 of the holding member 13, the safety is high. Moreover, although the pin body 16 is bent by a large load from the outside, its elastic restoring force makes it difficult for the pin body 16 to come out of the pin body housing portion 18.

Further, as in this embodiment, the holding member 13
An elastic material such as hard rubber or soft plastic is formed on the surface of the non-slip member having a projection 19 having a serrated cross section, and at least a part of the surface of the non-slip member is attached to the base of the body 12 of the accessory through the target T. By making contact with the back surface of 14, the accessory 11 can be reliably locked to the target T, and the target T is less likely to be damaged at the contact portion.

The present invention is not limited to the above-mentioned embodiment, but various modifications can be made if necessary.

[0032] For example, in personal ornaments pin of the locking mechanism before you facilities embodiment, the description of its use, has been described as stabbing the object toward the pin body upward, the tip of the pin body When the side is housed in the pin body housing portion, at least a part of the front surface of the holding member is in contact with the back surface side of the pin body via the object, and the object is sandwiched. In any direction in which the pin body faces, the locking mechanism of the accessory pin can safely and reliably lock the accessory to the target object. It is possible to obtain an effect that the T is less damaged. Further, the anti-slip member may be processed by forming a projection with an elastic material as described above or by coating a rubber film having a large friction coefficient. Furthermore, the locking mechanism for the accessory pin of the present invention is a technique applicable to piercing. In that case,
The pierce pin body is designed as shown in Fig. 1 in consideration of its attachment and safety.
As shown in 0 , the connecting portion between the base end side and the tip end side may be curved in an arc shape.
