Abstract
There is a vehicle power transmission device in which a continuously variable transmission and a gear train are provided between an input shaft and an output shaft so as to be able to transmit torque between the input shaft and the output shaft, the gear train has at least one speed ratio that cannot be set by the continuously variable transmission. In the vehicle power transmission device, a forward-reverse switching mechanism is arranged along the same axis as an axis of the input shaft, a first clutch mechanism and a brake mechanism are provided, a second clutch mechanism is provided in a first torque transmission path that is routed from the input shaft to the output shaft via the continuously variable transmission, a third clutch mechanism is provided in a second torque transmission path that is routed from the output element to the output shaft via the gear train.
