On an input and an output shafts of the transmission, there are provided a plurality of gear pairs which have different reduction ratios. One of the gears of the gear pair having the smallest reduction ratio is operably connected with the input shaft through a multi-disk clutch, and the torque transmitted from the input shaft to the gear can be controlled by adjusting the thrusting force applied to the clutch. When the selection of the gear pair is changed, the gear pair under operation at present is brought into the neutral condition and, at the same time, the thrusting force of the clutch is increased. Thereby, the torque of the input shaft is transmitted to the output shaft through the clutch and a rotational synchronism of the input and output shafts is advanced by adjusting the thrusting force. When the rotational synchronism is completed, the gear pair to be selected is brought under the operation.
