The bearing portion includes an eleventh cylindrical surface, which supports a motor shaft. The internal teeth of the first internal gear are arranged coaxial with the eleventh cylindrical surface. The internal teeth of the first internal gear and the bearing portion are formed as portions of the one-piece member.
