動機。[Claims for Utility Model Registration] 1. In an electric motor having a rotor in which a drive magnet formed by mixing magnetic powder into thermoplastic synthetic resin is attached to a cup-shaped yoke, an insertion hole is formed in the back wall of the yoke, The drive magnet has a fixing protrusion that is inserted into the insertion hole and protrudes, and the protruding tip is crushed by heat melting to become a retainer, and a fixing protrusion that comes into contact with the back wall of the yoke to position the yoke and the drive magnet. An electric motor formed with a regulating protrusion. 2. The electric motor according to claim 1 of the utility model registration claim, in which a fixing projection is formed on the yoke abutting end surface of the regulating projection.
