Abstract
The output rotation of an engine is transmitted to a drive member when a vehicle starts moving, and the drive member is connected to a carrier of a speed-increasing planetary gear via a start clutch. Upon engagement of the start clutch, the rotation of the drive member is accelerated by the speed-increasing planetary gear and then transmitted to an input shaft that is directly connected to a ring gear. Such rotation transmitted to the input shaft is shifted to a plurality of speeds and transmitted to an output shaft by using a plurality of friction engagement elements to selectively connect or fix elements of a single planetary gear set and a multiple planetary gear set that is connected to the output shaft.
