モータ。[Claims for Utility Model Registration] An electric motor, the rotor shaft of which has an oil-impregnated bearing member formed by impregnating a cylindrical member made of a porous material with lubricating oil, and an oil-impregnated bearing member disposed around the outer periphery of the oil-impregnated bearing member. By means of a bearing device including an oil retainer that replenishes lubricating oil to the oil-impregnated bearing member, and a housing that holds the oil-impregnated bearing member and the oil retainer,
In a rotatably supported electric motor, a stepped portion is formed at a portion of the rotor shaft that is recessed by a certain small dimension from at least one end surface of the oil-impregnated bearing member, and a portion inside the stepped portion is formed. A lubricating oil leak prevention type electric motor, characterized in that the large diameter portions contact the inner surface of the oil-impregnated bearing member, and the portion outside the stepped portion is a small diameter portion that does not contact the inner surface.
