Abstract:
1. A differential device for a vehicle, comprising: a differential mechanism including an input member which is rotatable by a driving torque inputted, differential members to which the driving torque is transmitted from the input member, a pair of output members connected to the differential members so as to be rotatable relatively to the differential members, wherein the differential mechanism being rotatable coaxially with the input member; and either a limited-slip differential for limiting a differential rotation of the differential mechanism or an intermittent unit for intermitting the driving torque, the limited-slip differential or the intermittent unit being arranged on either side of the differential members in an axial direction of the output members, wherein the limited-slip differential or the intermittent unit includes a clutch arranged adjacent to the differential members in an axial direction of the differential casing and an actuator arranged adjacent to the clutch in the axial direction of the differential casing to control a limited-slip differential force of the limited-slip differential or an intermittent function of the intermittent unit; the input member includes a cylindrical differential casing accommodating the differential mechanism, the differential casing including a flange part to which a ring gear for inputting the driving torque is fixed, the flange part is positioned on one side of the differential casing in the axial direction of the differential casing; the actuator includes an electromagnetic solenoid and a coil housing containing the electromagnetic solenoid; the coil housing is arranged so as to abut on the flange part, and accommodated in an annular supporting part, which is depressed on an axial end of the differential casing; and the differential casing is divided into casing pieces by a parting part on another side of the differential in opposition to the flange part in the axial direction of the differential casing, the casing pieces being connected with each other by connecting members.
