Claims

[Claims for Utility Model Registration] A compact device comprising a bearing held in a bearing holding part provided in a housing case and supporting a rotor shaft, with lubricating oil interposed between the bearing and the rotor shaft. In the motor, at least an inner surface of the bearing holder on the side that contacts the bearing, a predetermined area of the inner surface of the housing/case that is continuous with the inner surface of the bearing holder, and a surface of the rotor shaft that is in contact with the bearing. A small motor characterized in that a predetermined area on both sides of a contact surface is coated with an oil-repellent moisture-proof coating.
