Patent attributes
In a differential device including: an input member capable of being joined to a carrier supporting a plurality of planetary gears via a plurality of first shafts that respectively support the plurality of planetary gears; a differential gear supported on the input member via at least one second shaft and being able to rotate and revolve; and a pair of output gears each meshing with the differential gear, the input member includes a plurality of recessed portions on a wall of the input member facing the carrier, the plurality of recessed portions being able to be respectively fitted with the plurality of first shafts and being each arranged at a position deviated in a peripheral direction of the input member with respect to the at least one second shaft. Accordingly, deterioration in durability of a differential case due to formation of the recessed portions is suppressed.
