Abstract
A power transmission unit including a first clutch device that selectively enables and disables a torque transmitting route from an input shaft to an output shaft via a first gear train to transmit torque therethrough, a dog clutch that switches the torque transmitting route from the input shaft to the output shaft between a continuously variable speed change route in which torque is transmitted through a continuously variable transmission and a reverse route in which torque is transmitted through a second gear train, and a second clutch device that selectively enables and disables both of the continuously variable speed change route and the reverse route to transmit torque to the input shaft or the output shaft. The first clutch device and the second clutch device are separately disposed on any of the input shaft and the output shaft in a manner to be situated at different axial positions.
