Abstract:
A differential device has a differential case that houses a gear group, and a ring gear that is disposed fitted to the differential case. The differential case and the ring gear are supported rotatably about a drive shaft. The ring gear is made up of a helical gear. The ring gear abuts the differential case in the axial direction of the drive shaft. The ring gear and the differential case are welded at an abutting portion of the ring gear and the differential case in the axial direction of the drive shaft.
