ABSTRACT:
An object of this invention is to provide a bearing device for an electric motor in which a bearing holder holding an oil-impregnated bearing provides good area contact from the beginning and can be readily formed with high productivity. In the bearing device for an electric motor in which a bearing-supporting cylindrical recess is formed in one end face of a bearing holder in the form of a hollow cylinder, and an oil-impregnated bearing having a shaft-inserting hole is fixedly fitted in the bearing-supporting cylindrical recess in such a manner that the shaft-inserting hole of the oil-impregnated bearing is inclined with respect to the central axis P of the bearing holder; the bearing-supporting cylindrical recess of the bearing holder is defined by a cylindrical surface whose diameter is slightly smaller than the outside diameter of the oil-impregnated bearing and which is in parallel with the central axis P of the bearing holder, and an abutting annular surface inclined with respect to the central axis P, and the oil-impregnated bearing is arranged inclined in the bearing-supporting cylindrical recess being abutted against the abutting annular surface.
