<p>Pinion gears 4A and 4B are rotatably carried within pinion gear receiving openings 12A and 12B formed in a differential case 2. The inner surfaces (pinion gear holding surfaces) of the receiving openings 12A and 12B are enlarged inwardly to form extensions 12Aa and 12Ba to hold not only portions 4Ab and 4Bb of the pinion gears 4A and 4B which are located outwardly and which are to be held, but also part of inner meshing portions 4Aa and 4Ba of the pinion gears which are disposed in meshing engagement with the side gears 6A and 6B in an overlapping manner. This construction prevents a tilting of the pinion gears 4A and 4B and improves the durability.</p> |
