In a transmission including a multiple planetary mechanism into which power from a driving source is inputted through an input shaft, clutches are provided respectively for three components among a plurality of components included in the multiple planetary mechanism and are respectively disposed and capable of switching between connection and disconnection of transmission of power between the input shaft and the three components. Brakes are respectively provided between a transmission case and components among the plurality of components. The brakes are configured to make the components stationary relative to the transmission case. Two transmission mechanisms different from each other in speed reduction ratio are provided between an output shaft, which is parallel with the input shaft, and two components among the plurality of components. The two transmission mechanisms are provided in such a manner as to be capable of selectively switching transmission of the power to the output shaft side. Accordingly, it is possible to provide a transmission whose controllability of transmission is enhanced, and whose efficiency is improved by reducing the friction. |
