Abstract

PURPOSE: To extend the life of an auxiliary speed change unit by arranging such that no torque is transmitted to the auxiliary speed change unit at the time of the top range.
CONSTITUTION: At the time of the first speed or second speed, at which time an input shaft 4 and an output shaft 11 are not directly coupled to each other, the rotational force of the input shaft 4 is transmitted to an auxiliary speed change unit 30 through a clutch gear 9 and a gear 32. The rotational force transmitted to the auxiliary speed change unit 30 is further transmitted to a counter shaft 12 of a main speed change unit 7. At the time of the top range, at which time the input shaft 4 and output shaft 11 are directly coupled to each other, the rotational force of the input shaft 4 is not transmitted to the auxiliary speed change unit 30, so that idling of the auxiliary speed change unit is caused.
