PROBLEM TO BE SOLVED: To provide a transmission that can improve ride quality by improving a function of buffering spike torque generated in the shift transmission.SOLUTION: The power is transmitted to a main shaft 2 disposed on an engine E side and a counter shaft 3 disposed on a driving wheel side via a first gear train 31 to a sixth gear train 36. On the counter shaft 3, a selector mechanism 50a is provided which selects the first gear train 31 or a second gear train 32. On the main shaft 2, a low-speed gear stage buffer mechanism 100 is provided which rotates the main shaft 2 integrally with a main gear 10 if torque is less than predetermined set torque and which relatively rotates the main shaft 2 and the main gear 10 when the torque is more than or equal to the set torque. Between the counter shaft 3 and a first output shaft 5, a drive buffer mechanism 300 is provided which relatively rotates both of the shafts 3 and 5 when torque generated in the counter shaft 3 is more than or equal to limit torque. |
