PURPOSE:To suitable improve a speed change feeling, by bringing a second clutch into a semi-engaged condition during cutting off power transmission through a one-way clutch upon shifting a transmission. CONSTITUTION:A first clutch 22 is provided between a crank shaft 16 and an input shaft 18, while a second clutch 24 is provided between the crank shaft 16 and an output shaft 56. During running a vehicle, power of an engine 10 is transmitted through a one-way clutch 22 to the input shaft 18. Upon shifting a transmission 14, the second clutch 14 is brought into a semi-engaged condition during cutting off the power transmission through the one-way clutch 22. Accordingly, even in a period of shifting of the transmission 14, the power of the engine may be transmitted through the second clutch 24, thereby suitably improving a speed change feeling upon shifting the transmission. |
