1. A differential device comprising:
a differential case; and a differential mechanism housed in the differential case and distributively transmitting rotational force of the differential case to a pair of mutually-independent output shafts, wherein the differential case includes
an input member including an input part which receives the rotational force, an end portion of the input member on at least one side in an axial direction thereof being opened, andat least one cover portion covering the opened end portion of the input member on the one side in the axial direction, the input member includes
a welded portion to which the cover portion is fitted in the axial direction of the input member and joined by welding,a press-fitted portion located inward of the welded portion in a radial direction and the axial direction of the input member, the cover portion being press-fitted to the press-fitted portion, anda connecting surface connecting the welded portion and the press-fitted portion and forming a space between the connecting surface and the cover portion, the space allowing deformation of the press-fitted portion during the press-fitting, and the connecting surface includes one end portion continuous to the welded portion, the one end portion extending outward from the welded portion in the radial direction. |
