PURPOSE: A motor is provided to minimize vibration transmitted to a cover plate by absorbing vibration from a brush holder in a housing. CONSTITUTION: A case(23) comprises a housing and a cover plate(30) inserted into an opening(29) of the housing. A stator(22) is installed on the inner surface(21) of the case. A rotor(24) includes a rotation shaft(25), an armature(31), and a commutator(32). The commutator includes a terminal for connecting a coil(34).
