ABSTRACT:
An automatic transmission including a drive shaft directly connected to a drive source, an output shaft, and a planetary gear mechanism provided between the drive shaft and output shaft and serving to effect automatic speed change in power transmission. The planetary gear mechanism is mounted on the drive shaft with its sun gear fitted thereon. Thus, the length dimension of the drive shaft can be reduced to provide a very compact system. Further, a plurality of clutches are arranged in a radial plane between the drive shaft and the output shaft, thus permitting a further reduction in the size of the system.
