Disclosed is a differential gearing including: a case that is rotatable about the axis of rotation and has a shaft hole; a pinion pin that extends parallel to the axis of rotation; a pinion shaft that is supported by the case, has an axial end passing through the shaft hole of the case, and receives the rotational torque about the axis of rotation from the case through the axial end when the axial end abuts on the peripheral wall of the shaft hole as the case rotates about the axis of rotation; a pinion gear that is supported so as to be rotatable about the pinion shaft; and a side gear that meshes with the pinion gear. The pinion shaft has, on the axial end face, a groove that extends in the extension direction of the pinion pin. The pinion pin is fitted into the groove.
