Abstract
A differential case includes: two supported parts so supported that a differential case is rotatable around a central axis of the differential chamber; and a flange provided between the supported parts and projecting in an outer diameter direction, and welded with a ring gear. The flange includes a bearing surface and a rounded base disposed on one side of the differential case in an axial direction. The bearing surface is in contact with a surface, of the ring gear, disposed on opposite side of a tooth surface of the ring gear, and the rounded base is coupled in a continuous fashion to the bearing surface. A rounded part that disperses stress, generated at the rounded base by gear reaction force derived from the ring gear, is provided in a region between the flange and one of the supported parts disposed on the one side.
