Abstract

A pump housing, a fixing member and a holding member are assembled in the axis direction of an oil pump to fix a stator and a rotor of a brushless motor. The holding member is made of metal material and has a cylindrical shape that extends from its bottom portion toward one side in the axial direction. The fixing member is a cylindrical metal member. Stepped portions, extending in the circumferential direction, are formed in the outer periphery of the holding member and the inner periphery of the fixing member, and contact each other. The outer periphery of the holding member engages with the inner periphery of the fixing member. The outer periphery of the other end portion of the fixing member is fitted to the inner periphery of a flange portion projecting from the end face of the pump housing, which is adjacent to the brushless motor.
