ABSTRACT:
The present invention relates to a transmission apparatus (15) including at least one of a dividing unit (6) and a differential planetary gear unit (30), and a joint unit (20). A rotational power, which has been input to the transmission apparatus (15), is transmitted to the joint unit (20) via the dividing unit (6) or the differential planetary gear unit (30). A rotational power to be input to the joint unit (20) is smaller than the rotational power which has been input to the transmission apparatus (15), and the joint unit comprises a fluid coupling.
