Abstract:
[Problem] To reduce the step ratio during gear shifting in a unit having a motive power transmission mechanism therein. [Solution] This unit comprises: an input element; an output element; and a gear device in which a first rotation part, a second rotation part, a third rotation part, and a fourth rotation part are arranged in the stated order on a speed diagram. The input element can be connected to the first rotation part and the second rotation part, the output element can be connected to the third rotation part, and the fourth rotation part can be switched between a rotating state and a non-rotating state. The gear device is provided with a first planetary gear mechanism and a second planetary gear mechanism, the first rotation part is configured by coupling a first rotation element and a sixth rotation element, the second rotation part is configured by coupling a second rotation element and a fifth rotation element, the third rotation part is configured from a third rotation element, and the fourth rotation part is configured from a fourth rotation element.
