ABSTRACT:
A gear train for transmitting the rotation from an input shaft to an output shaft is constituted such that a plurality of speeds are set by a plurality of planetary gear sets, each of which is provided with components including a sun gear, a ring gear and a carrier, and one of the planetary gear sets on one of the speeds does not participate in the transmission of torque from the input shaft to the output shaft. Also, single or a plurality of uniting clutches are provided to selectively interconnect at least either two of the components in the planetary gear set adapted not to participate in the transmission of torque.
