PROBLEM TO BE SOLVED: To reduce noise characteristics by allowing a thruster engaged with a pair of spring devices to push a pair of side gears to the outside in the axial direction. SOLUTION: A pair of annular thrust blocks 60, 62 are arranged to be engaged in concentric contact with the interior of a central cam member 46. The contact faces of the thrust blocks 60, 62 are provided with lubrication grooves extending to the radial direction. The opposite faces of the thrust blocks 60, 62 are put in contact with disc spring washer groups 70, 72. The opposite end faces of the disc spring washer groups 70, 72 are received through corresponding holes in the opposed ends of side gears 20, 22. The degree of freedom of the side gears 20, 22 to be moved in the radial direction is restricted by applying axial force to the side gears 20, 22, thus reducing noises between teeth generated from a differential device. |
