To solve a problem wherein, in a working vehicle such as a UV vehicle with a known dual clutch type transmission being mounted thereon, complicated operations are necessary when frequently repeating the forward/backward drive, it takes time for changing the forward/backward drive, the working efficiency is degraded, a space necessary for the work is increased, and the work in a narrow space cannot be performed.
The speed stage having the lowest vehicle speed is selected as the forward speed stage in the reverse mode among the speed stages for power transmission by a clutch in an uncoupled state in a backward speed stage from a first clutch C1 having a reverse mode capable of freely selecting one forward speed stage out of the forward speed stages and the backward speed stage and coupling/uncoupling the power to the drive train group necessary for each odd number speed stage, and a second clutch C2 for coupling/uncoupling the power by the clutch in the uncoupled state in the backward speed stage.
