The invention provides a power transmission device for a vehicle, which can improve the start response when a vehicle restarts after stop. In the power transmission device for a vehicle with a crank type power transmission unit, if a stop intention detection unit detects the stop intention of a driver in decelerating running of the vehicle, a start resistance calculating unit calculates the start resistance of the vehicle and an offset control unit controls the offset of an eccentric disc in a range of greater than zero and less than a value generating an output torque basically equal to the start resistance in a period from the detection of the stop intention to the detection of the start intention of the driver by a start intention detection unit. Thus, while the stop state of the vehicle is maintained, the offset can be increased in advance, and the delay for increase of the offset to a necessary value is reduced at the moment of vehicle start, so that the start response is improved. The offset is increased from the decelerating running of the vehicle, so that even the vehicle is restarted after being just stopped, the start response is improved.
