Abstract
A differential apparatus includes a differential gear mechanism in which side gears mesh with pinion gears, a pinion shaft that rotatably supports the pinion gear, a slide member that supports the ends of the pinion shaft, and pinion gear washers each disposed between the slide member and a corresponding one of the pinion gears. Movement of each pinion gear washer toward the slide member in the axial direction of the pinion shaft is restricted. When a force of the pinion gear pressing the pinion gear washer toward the slide member is less than a predetermined value, a clearance is formed between the slide member and the pinion gear washer. When the force of the pinion gear pressing the pinion gear washer toward the slide member is greater than the predetermined value, the outer surface of the pinion gear washer abuts the inner surface of the slide member.
