Differential Unit
A differential unit includes: a differential case; a differential mechanism; a connecting-disconnecting member that connects the differential case to the differential mechanism; an actuator that generates a moving force for moving the connecting-disconnecting member; a moving-force transmitting member that transmits the moving force generated by the actuator to the connecting-disconnecting member; and a wave washer that urges the connecting-disconnecting member in a direction opposite to a direction in which the connecting-disconnecting member is moved by the actuator. The actuator includes a plunger that moves while compressing the wave washer in the axial direction from a first prescribed length using a magnetic force of an electromagnet. A movement of the plunger in a direction away from the connecting-disconnecting member is restricted by a contacting portion of a restricting member. An axial clearance is formed between the plunger and the contacting portion when the wave washer is at the first prescribed length.
