Abstract:
[Problem] To reduce the step ratio during gear shifting in a unit having a power transmission mechanism therein. [Solution] This unit is provided with: an input element; an output element; and a gear device that is configured by coupling, at one position, mutual rotatable elements of a first planetary gear mechanism and a second planetary gear mechanism, and in which a second rotary section, which corresponds to the coupled mutual rotatable elements, is disposed between a first rotary section and a third rotary section, and a fifth rotary section is disposed between the second rotary section and a fourth rotary section, on a collinear diagram. The input element is connected to the first rotary section, the output element is connected to the fifth rotary section, the third rotary section is fixed, the fourth rotary section is selectively connectable to a fixed element or to the first rotary section, and the fifth rotary section is connectable to the first rotary section.
