Claims

[Claims for Utility Model Registration] A pinion shaft that rotates integrally with a differential case, a pinion gear rotationally attached to the pinion shaft, and at least one of which meshes with the pinion gear and is freely disposed on an axle. a pair of side gears each having a first cam portion; a driving member spline-coupled to the axle and having a second cam portion that engages with the first cam portion; and the driving member and the differential case. A first clutch plate that engages with the drive member and a second clutch plate that engages with the differential case are arranged alternately between the two clutch plates, each end of which is engaged with the side gear and the drive member, respectively. and a coil spring disposed between the side gear and the drive member and having an axial expansion force and a radial expansion force or contraction force, the coil spring having a radial expansion force or contraction force. A differential limiting device characterized in that the cam surface of the first cam portion and the cam surface of the second cam portion are brought into pressure contact.
