Patent ID: 7775926

Claim:
A differential device for a vehicle, comprising: a differential casing having a cylindrical part, a first sidewall and a second sidewall formed on both sides of the cylindrical part in an axial direction thereof, a first boss part and a second boss part formed outside the first and the second sidewalls in the axial direction and a flange part formed on the outer circumference of the first sidewall; a differential mechanism having a differential member to which a driving force is transmitted from the differential casing, and a first output member and a second output member both engaged with the differential member to thereby distribute the driving force; a diff lock mechanism having a clutch member rotatable integrally with the first sidewall and connectable with the first output member by a relative movement of the clutch member to the first sidewall in the axial direction of the cylindrical part and an actuator for moving the clutch member in the axial direction of the cylindrical part; and a differential restraint mechanism having a clutch arranged on the side of the second sidewall, for restraining a relative rotation of the differential casing to the second output member.
