Abstract: A motor includes a first housing having a groove, a rotor inserted into the groove and rotatably provided outside the first housing, a second housing coupled to the first housing to form a space together with an outer circumferential surface of the groove, a stator provided in the space, a rotation shaft coupled to the rotor and extended in one direction, and a sealer coupled to the first housing to surround the rotation shaft. The sealer includes a base rotatably coupled to the rotation shaft, a gasket brought into contact with an outer circumferential surface of the rotation shaft, and a cover coupled to the base to fix the gasket to the base. The base includes a first annular protruding portion spaced apart from the rotation shaft to support the gasket, and a second annular protruding portion spaced apart from the first annular protruding portion to support the gasket.
