A set of odd-numbered gears and a set of even-numbered gears are arranged respectively across the first input shaft and second input shaft and an output shaft. When a vehicle starts, a start gear and a support gear are synchronously engaged to the second input shaft and the first input shaft, respectively, and simultaneously connecting the first clutch and the second clutch partially (half clutch state) to the first input shaft and the second input shaft, respectively, the support gear having a gear ratio smaller than that of the start gear by one speed or higher.
