PURPOSE: A stepping motor is provided to improve the reliability of the stepping motor by combining a protrusion of a cover with a bracket. CONSTITUTION: The stepping motor comprises a bracket(110), a stator, a cover(130), a lead screw(150), and a rotor. The stator is combined with the bracket. The cover is combined with the stator. The cover prevents the stator from being separated from the cover. The rotor is combined with the lead screw. The rotor rotates the lead screw. The cover comprises a coupling plate(131), a supporting tube(133), and a plurality of protrusions(135).
