Beschreibung
Zusammenfassung:	Provided is a power transmission device for a hybrid vehicle that, when starting an engine by using a traction motor while the vehicle is being driven by the motor, can start the engine while suppressing transmission of torque variation of the motor to a driving wheel and can suppress an increase in a differential rotation speed of a clutch for starting the engine. A power transmission device for a hybrid vehicle includes first clutch means (1a) that is capable of transmitting or cutting off driving power of an engine (E) to driving wheels (D), and second clutch means (1b) that is capable of transmitting or cutting off power of a motor (M) to the driving wheels (D). The power transmission device is capable of appropriately operating the first clutch means (1a) and the second clutch means (1b) in accordance with driving conditions of the vehicle. When starting the engine (E) by transmitting power from the motor (M) to the engine (E) via the first clutch means (1a) and the second clutch means (1b), the power transmission device slip-controls the first clutch means (1a) and the second clutch means (1b).
