ABSTRACT:
A stepping motor according to the present invention used in a case containing oil includes a motor having a coil formed with a conductor wound around a bobbin and a cover member enclosing the coil, and a housing which houses the motor. The cover member serves to protect the coil from being directly subjected to molding pressure when the housing is injection-molded.
