ABSTRACT:
A differential apparatus includes a differential casing, a pair of side gears and plural pairs of pinion gears. The pinion gears are accommodated in bores formed in the differential casing, respectively. Each pinion gear has an outer diameter smaller than that of a standard gear to be determined corresponding to predetermined gear specifications. With such a forming of the pinion gears, the tip circular thickness of each pinion gear is increased, so that surface pressure at respective tips of the pinion gears is reduced to improve the seizure resistant capability.
