Abstract
An input system includes a first input shaft provided with forward drive gearwheels of one gear group of two predetermined gear, a second input shaft provided with forward drive gearwheels of the other gear group and being rotatable about an axial center of the first input shaft, and clutches provided at end portions of the first and second input shafts. An output system includes first and second output shafts provided parallel to the first and second input shafts, a forward gear mechanism including forward driven gearwheels provided on the first and second output shafts meshing with the forward drive gearwheels and synchromesh mechanisms, and a reverse gear mechanism including a reverse driven gearwheel, a synchromesh mechanism, and an idler gearwheel being rotatable together with a forward driven gearwheel for a low gear meshing with the reverse driven gearwheel. A final reduction ratio of one of the output shafts which outputs rotational power from the reverse driven gearwheel is larger than a final reduction ratio of the other of the output shafts.
