A first clutch (2) is connected to an engine (1) of a hybrid vehicle. A motor/generator (6) is connected to an output shaft (4) of the first clutch (2) through a planetary gear set (3). A second clutch (10) is provided which connects an input shaft (5) of an automatic transmission (7) to the output shaft (4) so as to move the vehicle forward, and which connects the input shaft (5) to the motor/generator (6) so as to move the vehicle rearward. The second clutch (10) preferably comprises a dog clutch. When the vehicle commences forward motion, the torque of the motor/generator which is input to the automatic transmission (7) can be increased since the planetary gear set (3) decreases the rotation speed of the motor/generator (6) and transmits it to the output shaft (4).
