Abstract
A differential apparatus includes a differential mechanism, a differential case that accommodates the differential mechanism, and a clutch mechanism that transmits a driving force between the differential case and the differential mechanism. The clutch mechanism includes a slide member movable inside the differential case in an axial direction and an actuator. The slide member has a first meshable portion at one end in the axial direction, is allowed move relative to the differential mechanism in the axial direction, and is prevented from rotating relative to the differential mechanism. The differential case includes a first case member and a second case member that are united to form the differential case. The first case member integrally includes a second meshable portion and a flange portion that the ring gear is fastened to. When the actuator is activated the first meshable portion meshes with the second meshable portion so that the differential case and the slide member are coupled to present a relative rotation between the differential case and the slide member.
