The present invention relates to a transmission apparatus () including at least one of a dividing unit () and a differential planetary gear unit (), and a joint unit (). A rotational power, which has been input to the transmission apparatus (), is transmitted to the joint unit () via the dividing unit () or the differential planetary gear unit (). A rotational power to be input to the joint unit () is smaller than the rotational power which has been input to the transmission apparatus (), and the joint unit comprises a fluid coupling.

Transmission apparatus

A differential planetary gear apparatus has a single-pinion-type structure in which one planetary gear () is arranged in a radial direction and one or more planetary gears () are arranged in a circumferential direction in a region between a sun gear () and a ring gear (), a drive source (), a speed-change motive source (), and a driven unit () are disposed at any one of an input side (I), an output side (O), and a speed-change side (T), respectively, and the speed-change motive source () includes an electric motor.
