ABSTRACT:
Pinion gears are rotatably carried within pinion gear receiving openings formed in a differential case. The inner pinion gear holding surfaces of the receiving openings are enlarged inwardly to form extensions to hold not only portions of the pinion gears that are located outwardly and that are to be held, but also part of inner meshing portions of the pinion gears that are disposed in meshing engagement with side gears in an overlapping manner. This construction prevents a tilting of the pinion gears and improves the durability.
