ABSTRACT:
A differential apparatus having a limited slip differential mechanism which comprises a differential case, a pair of side gears housed in the differential case and connected to driving shafts, and pinion gears meshing with the pair of side gears. One of the tooth surfaces of each tooth of the side gears and the pinion gears has a large pressure angle and the other surface has a small pressure angle, such that meshing reaction forces Dr in a drive mode is larger than that of Co in a coast mode to obtain different limiting forces.
