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 that is configured by coupling a first planetary gear mechanism and a second planetary gear mechanism to respective rotating elements at one location, the gear device being such that, on a collinear diagram, a second rotation part is disposed between a first rotation part and a third rotation part that are the coupled respective rotational elements, and a fifth rotation part is disposed between the first rotation part and a fourth rotation part. The input element is connected to the first rotation part. The output element is connected to the fifth rotation part. The third rotation part is fixed in place. The fourth rotation part can be selectively connected to a fixed element or the second rotation part. Any specific two of the first rotation part, the fourth rotation part, and the fifth rotation part can be connected to and disconnected from each other.
