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