Abstract
A motor is provided which includes a housing, a stator attached to the cylindrical wall of the housing, a sleeve bearing attached to the inner periphery of the cylindrical wall, a rotor rotatably supported by the sleeve bearing, and a rotor magnet attached to the rotor. A plurality of projecting strips are formed substantially at equal intervals on the inner and/or outer periphery of the cylindrical wall of the housing. The cylindrical wall is formed into a shoulder and a mating recess. The stator has elastic pieces. Because of the operation of the elastic pieces, the stator is elastically retained between the shoulder and the mating recess. Circuitry for protecting the motor is improved.
