PURPOSE:To eliminate reversal in a transmitting direction of transmitted torque acting on a belt, by transmitting power only in time of forward movement via a stepless transmission, and transmitting the power with a transmission gear alone in time of backward movement. CONSTITUTION:An output shaft 13 is connected to a final gear 5 via a first output gear 34 at ordinary times, while an input shaft 11 is made attachable to a clutch output shaft 16 and vice versa, and this clutch output shaft 16 is attachably or detachably connected to or from a second intermediate shaft 44 paralleled with the input shaft 11, whereby a second output gear 46 installed in the second intermediate shaft 44 is connected to the final gear 5, and such select devices 20 and 50 that selectively connect a first transmision route ranging from the clutch output shaft 16 to the input shaft 11 to a second transmission route ranging likewise from the clutch output shaft 16 to the second output gear 46 are installed so that reversal in a transmitting direction of transmitted torque acting on a belt 15 in a stepless transmission comes to nothing, thus durability in the belt 15 is well improved. |
