A differential device is provided with a case rotatable about an axis; an input member configured to receive the torque from the input shaft, the input member being housed in the case and including an engaging outer periphery drivingly engaged with the case; first and second output gears configured to respectively drivingly link with the output shafts, the first and second output gears being rotatably housed in the case to form a row with the input member along the axis; one or more first pinions being rotatably housed in the case in parallel with the axis and meshing with the first output gear, the first pinions having no overlap with the engaging outer periphery of the input member and the second output gears; and one or more second pinions being rotatably housed in the case in parallel with the axis and meshing with the second output gears and the first pinions, the second pinions extending beyond the input member to reach the first pinions.
