Abstract
A differential apparatus includes a differential case, a pinion gear that is rotatably supported in the differential case and revolves as the differential case rotates, and side gears that respectively mesh with the pinion gear. The side gears are relatively rotatable with each other. A first planar portion orthogonal to a rotation axis is provided on a back side each of the side gears. A second planar portion which can abut against the first planar portion is provided in the differential case. A first abutment force is applied between the first planar portion and the second planar portion by a biasing member. A meshing reaction force between the pinion gear and the side gear applies a second abutment force between the first planar portion and the second planar portion.
