Abstract
A differential device includes: a differential case on which a meshed portion is formed; a tubular slide member that has a meshing portion; a differential gear mechanism disposed inside the slide member; a pinion gear shaft that supports pinion gears of the differential gear mechanism; and an actuator that moves the slide member in the axial direction. The slide member has a cylindrical portion, on one side of which in the axial direction the meshing portion is formed, and a long hole that extends in the axial direction of the cylindrical portion and that opens toward the other side in the axial direction, which is the opposite side from the meshing portion. The pinion gear shaft is fitted with the long hole, and supported by the slide member. A reinforcing ring that suppresses deformation of the slide member is attached to an end portion of the cylindrical portion in which the long hole opens.
