Provided is a power transmission device for a hybrid vehicle that rotates an oil pump at an appropriate speed and that reduces unnecessary rotation of the oil pump. The power transmission device for a hybrid vehicle includes first clutch means (1a) that is disposed in a drivetrain extending from an engine (E) to a driving wheel (D), second clutch means (1b) that is disposed in a drivetrain extending from a motor (M) to the driving wheel (D), and an oil pump (P) that is connected to the motor (M) and that is capable of supplying oil to a predetermined moving component disposed in the vehicle by using driving power of the motor (M). The power transmission device includes a transmission (A) that is disposed in a drivetrain between the engine (E) and the motor (M) and the driving wheel (D) and that is capable of adjusting rotation speed of the motor (M), and the power transmission device is capable of supplying oil by causing the motor (M) to rotate the oil pump (P) at an appropriate rotation speed.
