Claims

[Scope of utility model registration request]

A ring-shaped plastic magnet 1 has a plurality of joining protrusions formed on its upper and lower surfaces, and a plurality of holes into which a pole 2 is protruded from the center and through which the joining protrusions are inserted on the lower surface of the plastic magnet 1. a lower plate 3 formed with holes; an upper plate 4 formed with a plurality of holes through which the joining protrusions on the upper surface of the plastic magnet 1 are inserted;
It consists of a frame 5 having a plurality of holes drilled at the bottom through which the joining protrusions on the upper surface of the plastic magnet 1 are inserted, and the plastic magnet 1 is inserted into the upper surface of the lower plate 3 through the joining protrusions through the holes. At the same time, the upper plate 4 and the frame 5 are placed on the upper surface of the plastic magnet 1 with the bonding protrusions inserted into their respective holes, and heated. 1 and the upper plate 4 are bonded together by thermocompression, and the protruding part of the joining protrusion is deformed and enlarged to be fixed to the bottom of the frame 5.
