A vehicle power transmission device includes a forward first clutch between an engine and an input shaft of a continuously variable transmission, and a second clutch between an output shaft of the continuously variable transmission and driving wheels. When the hydraulic fluid of the hydraulic pump is not supplied to the first disconnection device and the second disconnection device, a dragging torque generated in the second disconnection device is larger than a dragging torque generated in the first disconnection device.
