Abstract
In a differential device distributing rotational force acting on a differential case to a pair of output shafts, the differential case including an input member and a cover portion, assembling precision of the differential device is enhanced by suppressing strain due to welding and press-fitting. The input member includes: a welded portion fitting the cover portion in axial direction and joined by welding; a press-fitted portion located inward of the welded portion in radial direction and axial direction and press-fitted to the cover portion; and a 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 press-fitting. The connecting surface includes one end portion continuous to the welded portion and extending outward from the welded portion in radial direction.
