ABSTRACT:
A differential apparatus has a differential casing, a pinion gear, a pair of side gears engaged with the pinion gear, and a cone clutch for limiting a differential movement between the side gears. In this differential apparatus, the cone clutch is constructed by a female side cone portion formed in an inner circumference of the differential casing, and a male side cone portion formed in an outer circumference of the pair of side gears. The female side cone portion is formed in the shape of a tapered face in which a conical generating line is a straight line. The male side cone portion is formed in the shape of a tapered face having a predetermined curvature and a generating line projecting to the female side cone portion. Thus, no sliding portion is offset to a small diameter portion even when thrust applied to the cone clutch is increased, thereby improving durability of the cone clutch.
