Differential apparatus

摘要

A differential apparatus is provided with a case; a pinion gear; a pair of side gears meshing with the pinion gear; a spherically depressed pinion gear supporting surface portion formed on an inner surface of the case to support a spherically projecting back side portion of the pinion gear; and spherically depressed side gear supporting surface portions formed on the inner surface of the case to respectively support spherically projecting back side portions of the side gears. The projecting back side portions of the side gears which are slidable on the depressed side gear supporting surface portions are formed on tooth portions of the side gears.

1. A differential apparatus comprising:
a case; a pinion gear supported in the case so as to rotate about its own rotational axis; a pair of side gears which are supported in the case and mesh with the pinion gear, wherein the side gears are rotatable relatively to each other; a pinion washer; a spherically depressed pinion gear supporting surface portion which is formed on an inner surface of the case and adapted to support a spherically projecting back side portion of the pinion gear via the pinion washer so that the pinion gear is slidingly rotatable about its own rotational axis; and spherically depressed side gear supporting surface portions which are formed on the inner surface of the case and adapted to respectively support spherically projecting back side portions of the side gears so that the side gears are slidingly rotatable about their own rotational axes, wherein the projecting back side portions of the side gears which are slidable on sides of the depressed side gear supporting surface portions are formed on tooth portions of the side gears.
