Abstract
The transmission is constructed so that the rotation of the input shaft is outputted to the second transmission portion via the first intermediate output path and the second intermediate output path accelerated and rotated with respect to the first intermediate output path, and the first rotary element is selectively connected to the first driven gear via the first clutch and is selectively connected to the second driven gear via the third clutch, the second rotary element are selectively connected to the first driven gear via the second clutch and are selectively connected to the transmission case operating as a non-rotating member via the first brake, the third rotary element is connected to the output gear, the fourth rotary element is selectively connected to the transmission case via the second brake, and the fifth rotary element is selectively connected to the second driven gear via the fourth clutch.
