Abstract
A planetary gear mechanism has a sun gear disposed to a rotating shaft, a plurality of pinion gears, a carrier supporting the plurality of the pinion gears, a ring gear meshing with the pinion gear on the outer diameter side of the carrier and a case holding the ring gear on the outer diameter side thereof. The ring gear is slidable in the axial direction of the rotating shaft with respect to the case. The planetary gear mechanism has a load transmission member abutting to an inner diameter side end portion of the ring gear and holding the carrier and the ring gear so as to be relatively rotatable. The load transmission member transmits an axial load from the ring gear to the carrier.
