A carrier comprises external teeth formed at an outer circumferential surface. The movable ring gear is movable between position in which the movable ring gear is engaged with the cover, relative to rotate to the cover, where a gear train has a high gear ratio, and another position in which the movable ring gear is connected to the cover, where the gear ratio of the gear train is low.
