A stepping motor is provided to perform an uniform welding by inserting a side plate of a bracket into a housing and welding an outer surface of the housing by a laser. A stepping motor includes a bracket(110), a housing(120), a stator, a lead screw, and a rotor. The bracket includes a support plate(111), and first and second side plates(113,115). The first and second plates are formed in both end portions of the support plate. The housing has a shape corresponding to the first side plate. One surface of the housing is opened and thus the first side plate is inserted into the housing. The stator is installed in an inside of the housing. One end portion of the lead screw penetrates the stator and is supported on the other surface of the housing. The other end portion of the lead screw is supported on the second side plate and is installed to rotate in a forward direction and a revere direction. The rotor rotates the lead screw in the forward direction and the reverse direction.
