    摘要: A stepping motor is provided with a plate spring for pressing a housing and a rotor against each other. One of the housing and the rotor is provided with a projection. Variations in position, which is inherent in position control by a related art stepping motor, due to lack of a retaining force subsequent to an initial position setting or due to variations in rotating speed of the motor, are eliminated. Thus the motor is suitably used for controlling of the position of, for example, an HID lamp unit.
