ABSTRACT:
A built-up stepping motor includes upper and lower housings each having an internal space and joined together with a support plate disposed therebetween. The lower housing retains therein a stator and a rotor disposed in the stator, while the upper housing holds therein a reduction gear for reducing the output speed of the motor. The output end of a rotor shaft extends through the support plate and meshes with a first gear of the reduction gear. The upper and lower housings are assembled together by interlocking engagement between locking projections and mating holes. A shock-absorbing damper is disposed between two stator cores to protect them against chattering.
