Abstract
A brush motor includes a case, a rotor containing a wiring portion wound around an iron core fixed to a shaft, a bearing making a sliding contact with the shaft to support the shaft, and a holder holding the bearing. The holder is made of resin, and includes a central portion with a cylindrical shape, containing an inner circumferential side into which the bearing is inserted, and a top portion protruding from an opening formed in the case; and an outer circumferential portion shielding the inner surface side of the exterior case and the winding portion. Thereby, the reliability of the motor can be improved.
