Abstract
A differential device includes a differential casinghaving a cylindrical part, first and second sidewallsformed on both sides of the cylindrical partand a flange partformed on the outer circumference of the first sidewall, a differential mechanismhaving a differential memberto which a driving force is transmitted from the differential casingand first and second output membersboth engaged with the differential memberto distribute the driving force, a diff lock mechanismhaving a clutch memberrotatable integrally with the first sidewalland connectable with the first output memberby a relative movement of the clutch memberto the first sidewallin the axial direction of the cylindrical partand an actuatorfor moving the clutch memberin the axial direction of the cylindrical partand a differential restraint mechanismhaving a frictional clutcharranged on the side of the second sidewall, for restraining a relative rotation of the differential casingto the second output member
