<p>To realize a small-sized differential gear provided with both differential limiting and locking functions simultaneously without markedly modifying the conventional differential case, the differential gear comprises a differential mechanism having a differential case (49), pinion shafts (63), pinion gears (69), two side gears (71, 73), etc.; two frictional multiplate clutches (83, 85) disposed between the two side gears and two inner side wall surfaces of the differential case, respectively for limiting differential function; a lock clutch (87) disposed within the differential case for generating two opposite direction thrust forces to engage said limit multiplate clutches into engagement and further locking the differential function; and actuator for actuating the lock clutch from outside of the differential case.</p> |
