摘要： A stepping motor as a driving device has a stator with a plate part, and first and second outer magnetic pole parts axially extending from the plate part. A rotor formed by a rotary shaft and a core, each formed of a soft magnetic material, are disposed between the outer magnetic pole parts. The rotor has one axial end rotatably supported in the plate part. A magnet is rigidly fitted on an outer periphery of the rotor and magnetized such that different poles circumferentially alternate. A top plate is rigidly secured to the respective foremost ends of the pole parts and rotatably supports the other axial end of the rotor. The pole parts are engaged in a bobbin having a cover part covering the outer peripheral surface of the magnet. First and second coils are wound around the outer magnetic pole parts via the bobbin.
