を行うようになされている。2. Description of the Related Art A motor for a timepiece is constructed by mounting an iron core at one end of a coil bobbin and winding a covered coil wire several times. By energizing the coil wire, the iron core is magnetized, and various mechanisms (particularly, a rotor) of the timepiece are driven by the attraction or repulsion of the generated magnetic force. The coil bobbin is made of plastic insulating material. This bobbin prevents the iron core and the coil wire from coming into contact with each other and prevents the sharp edge of the iron core from peeling off the coil wire. In this way, a short circuit at the time of energization is prevented.
