PROBLEM TO BE SOLVED: To enable smooth gear change of a twin clutch type transmission. SOLUTION: Since gears 31-34 of a first gear group provided in a first auxiliary input shaft 13 to which driving force of a main input shaft 12 is transmitted through a first clutch 24 and gears 37-39 of a second gear group provided in a second auxiliary input shaft 14 to which the driving force of the main input shaft 12 is transmitted through idle gears 17-19 and a second clutch 25 share gears 43-46 of a third gear group provided in an output shaft 16, reduction in the number of components and the size of the transmission can be achieved. Since a forward/backward relationship between switching timing of the first and second clutches 24, 25 and switching timing of a synchronizer is optional during achievement of any gear change stage, gear change shock caused by shift of the timing can be prevented, so as to enable smooth gear change.
