PURPOSE: A stepping motor is provided to reduce electrical noise by connecting a contact to a ground terminal. CONSTITUTION: A stepping motor comprises a bracket(110), a stator, a cover(130), a lead screw(150), a rotor, and a ground terminal(190). The stator is installed inside the bracket. The cover prevents the stator from being separated from the cover. The lead screw is supported by the cover and the bracket. The rotor is combined with the lead screw. The rotor rotates the lead screw. The ground terminal is connected to the cover and the substrate. The ground terminal attenuates electrical noise.
