Abstract

The differential includes a differential casing configured to be rotatably driven by a motor under a driving force. The differential includes a differential mechanism which includes a pair of first and second side-gears for distributing a torque of the differential casing to first and second output shafts. The differential includes a frictional clutch for interconnecting the first and second output shafts. The frictional clutch includes first and second power-transmitting members connected to first and second output shafts respectively and first and second clutch plates. The first and second clutch plates are connected to the first and second power-transmitting members respectively. The differential includes an actuator for operating the frictional clutch. One output shaft of the first and second output shafts is axially displacable by the actuator under an engagement force to engage the frictional clutch.
