ABSTRACT:
A differential unit which can be arranged in compact as a whole, while a differential limit and a differential lock are appropriately executed. The differential unit is provided with a differential mechanism transmitting from a differential case (45) to a pair of axle shafts a rotational force while allowing a differential rotation, and is provided with a differential limiting mechanism (57) which can limit the differential rotation, and a differential lock mechanism (59) which can lock up the differential rotation. The differential limiting mechanism (57) is provided with a limiting actuator (63) for operation, the differential lock mechanism (59) is provided with a lock actuator (67) for operation, and the limiting actuator (63) and the lock actuator (67) are independently arranged in both sides of the differential case (45).
