ABSTRACT:
A transmission is equipped with a planetary gear type transmission unit disposed between an input member and an output member within a casing. The transmission unit is comprised of a sun gear, a ring gear and a plurality of planet gears carried by a carrier coupled with the output member. The planet gears are in mesh with the sun gear and the ring gear. The input and output members are coupled with each other by bypassing the gears of the transmission unit in direct drive or via these gears in reduction ratio drive. The transmission is further provided with a first change-over member in mesh with the input member for selectively connecting the input member with the carrier in direct drive or with the sun gear in reduction ratio drive and a second change-over member secured to the first change-over member for engaging the ring gear with the casing in reduction ratio drive or disengaging the former from the latter in direct drive.
