Beschreibung
Zusammenfassung:	Provided is a differential device, comprising a differential case that houses a gear group, and a ring gear disposed fitted to the differential case, wherein the differential case and the ring gear are supported rotatably about a drive shaft. The ring gear comprises a helical gear having a ring-like structure, the ring gear abuts the differential case in an axial direction of the drive shaft, and the ring gear and the differential case are welded at an abutting portion between the ring gear and the differential case from outside in a radial direction of the ring gear. The ring gear has a gear portion on an outer periphery of the ring gear and a fitting portion fitted to the differential case on an inner periphery of the ring gear, and the gear portion is disposed completely outside the whole differential case in the radial direction of the drive shaft.
