摘要：
A movable sleeve of a second clutch is provided between a cylindrical ring gear and a cylindrical shaft of a differential case of a differential gear unit. In a disconnect mode in which a propeller shaft is disconnected from rear wheels, the cylindrical ring gear is disconnected from the differential case by the movable sleeve of the second clutch. Thus, in the disconnect mode, a fully differential state of the differential gear unit is prevented.
