Abstract:
[Problem] To reduce a step ratio during gear-shifting in a unit having a power transmission mechanism therein. [Solution] This unit comprises: an input element; an output element; and a gearbox in which a first rotating part, a second rotating part, a third rotating part, and a fourth rotating part are aligned in that order in a velocity diagram. The input element is capable of connecting to the first rotating part and of connecting to the second rotating part. The output element is connected to the third rotating part. The fourth rotating part is capable of switching between a rotational state and a non-rotational state. The gearbox comprises a first planetary gear mechanism and a second planetary gear mechanism. The first rotating part is constituted of a third rotating element. The second rotating part is constituted by linking a second rotating element and a sixth rotating element. The third rotating part is constituted by linking a first rotating element and a fifth rotating element. The fourth rotating part is constituted of a fourth rotating element.
