Claims

[Scope of utility model registration request]

It consists of a mounting bracket with a needle protruding from the inner periphery of a metal ring, and a non-magnetic metal body, the periphery of which bulges inward and a bag groove into which the needle of the mounting bracket is inserted opens outward. The female part of the stopper has a magnetic metal piece installed in the recess on the inner surface of the disc body, and the male part of the stopper has a magnetic metal piece attached to the inner surface of the disc body. A magnetic metal disc and an annular permanent magnet with a through hole in the center are placed on top of each other in a recessed part on the side, and these are surrounded by a cylindrical case made of a non-magnetic material.
The rivet for caulking the magnetic metal disc and the disc body is made by raising the cylindrical body as an extension of the rivet so as to pass through the through hole of the annular permanent magnet, and attaching its end to the upper surface of the non-magnetic case. A stop using a permanent magnet, characterized in that the periphery is exposed so that almost no protrusion is exposed.
