Abstract
According to the present invention, a cylindrical side wall is provided in a housing so as to surround an outer periphery of a stopper member. Further, an end surface of the side wall is higher than a top surface of outermost periphery of the stopper member. Oil otherwise scattered is received by the side wall for collection. Oil is thus prevented from scattering even if during manufacturing, the amount of oil dripped between the shaft and the oil-impregnated bearing is not strictly controlled, so that a slightly excessive amount of oil is dripped. Therefore, the present motor device enables manufacturing operations to be favorably performed, and is reliable having a long lifetime.
