According to the present invention, there is provided a metal clasp for an earring according to the present invention. At least a pair of elastic pieces bent in a loop toward the back of the guide portion are continuously and integrally provided so as to abut on the center line of the through hole, and a cylindrical guide is provided in the through hole provided in the guide portion. When the piece is fitted and the pin of the pierced earring inserted into the through hole is held by the elastic piece, the guide piece guides the insertion of the pin into the contact part of the elastic piece. is there.

[0007] In the earring stopper of the present invention, the cylindrical guide piece is made of plastic or rubber, has a retaining flange portion on both sides thereof, and one of the flanges is inserted into a through hole provided in the guide portion. It is also characterized in that the guide piece is mounted in the through hole of the guide portion by press-fitting the retaining flange portion.

[0008] The earring clasp of the present invention is characterized in that the cylindrical guide piece is made of a plastic or rubber elastic material, and the pin insertion hole is formed slightly smaller than the outer diameter of the pin. It is.

As described above, according to the earring fastener of the present invention, since the guide piece is attached to the guide portion, the inserted pin is prevented from coming off by both the guide piece and the contact portion of the elastic piece. Therefore, it is possible to reliably prevent the stopper from falling off the pin. Further, the inserted pin is guided by the guide piece so as to be substantially straight, so that the pin can be inserted without wobbling to the contact portion of the elastic piece.
