Provided is a power transmission device for hybrid vehicles which, when an engine using a traction motor is started while the motor is running, suppresses the transmission of torque fluctuations of the motor to a driving wheel allowing the engine to start, and suppresses the increase in the differential rotation of a clutch for starting the engine. This power transmission device for hybrid vehicles comprises: a first clutch means (1a) which allows the transmission or the interruption of the driving force of an engine (E) to a driving wheel (D); and a second clutch means (1b) which allows the transmission or the interruption of the driving force of a motor (M) to the driving wheel (D). The first clutch means (1a) and the second clutch means (1b) can be optionally operated according to the traveling state of a vehicle. The first clutch means (1a) and the second clutch means (1b) are slip-controlled when starting the engine (E) by transmitting a driving force to the engine (E) from the motor (M) through the first clutch means (1a) and the second clutch means (1b). |
