Abstract
A differential apparatus comprises: a differential gear (1) rotatably housed in a left end within a carrier case (3); a speed increasing mechanism and reducing mechanism (31) housed within the carrier case (3) in such a manner as to be adjacent to the rear differential apparatus (1), having a speed increasing mechanism (37) for increasing a rotational speed and a speed reducing mechanism (39) for reducing the rotational speed of the input gear (33) connected to a differential case (11) in a parallel manner; a speed increasing and reducing clutches (53) mounted to the carrier case (3) and for connecting and disconnecting the rotation from the input gear (33) which are arranged in a plane crossing to axes of output shafts (21,23) in parallel.
