Abstract
A vibration-proof stepping motor of the type having a stator of a built-up construction is disclosed, wherein the stator is composed of a single socket-like stator core member and a plurality of plug-like stator core members assembled with the socket-like stator core member in stacking relation, with stator coils disposed between adjacent pairs of the stator core members. An upper end of the plug-like stator core members which are stacked in the socket-like stator core member together with the stator coils projects from an upper end of the socket-like stator core member. A bobbin of each of the stator coils is resiliently deformable so that the stator is firmly retained by and between upper and lower housings in a compressed condition when the housings are joined together. With the stator thus retained, the stepping motor is free from vibration which would otherwise lead to generation of unpleasant operation noise.
