Abstract
A clutch devicehas a diff caserotatable with drive torque, side gearsto which the drive torque is transferred from the diff case, a clutch ringheld in constant connection to the diff caseand axially movable to the side gearsto be intermittently coupled thereto, and an electromagnetic actuatoroperative to axially move the clutch ring. The electromagnetic actuatorincludes an electromagnetic solenoid, and a plungeraxially movable in response to magnetic force of the electromagnetic solenoidfor axially moving the clutch ring. The electromagnetic solenoidis disposed on the diff caseso as not to relatively move in an axial direction, and the diff caseforms a part of a magnetic flux path of the electromagnetic solenoid
