[Object] Quietness is to be more effectively improved, without compromising stability in power transmission. [Solution] An annular internal gear member 24 is formed of a noise suppressing material having lower strength than a metal. A deformation restricting portion 22d of an annular flange shape is formed along an outer circumferential edge of a carrier 22. Accordingly, when a planetary gear mechanism is operating the internal gear member 24 is partially deformed so as to protrude radially outward of the annular shape. At this point, the protruding deformed portion of the internal gear member 24 abuts against an inner circumferential surface of the deformation restricting portion 22d. Therefore, deformation of the internal gear member 24 is effectively restricted.
