Abstract: Disclosed is a transmission device for work vehicles, said transmission device being capable of being used with high-horsepower engines, without an accompanying loss of power transmission efficiency or fuel economy. The transmission device is provided with: an input shaft that transmits power from an engine; a continuously-variable transmission that is disposed on the input shaft and outputs power transmitted from the input shaft, steplessly converting the speed thereof; and a reversing clutch device that outputs, either in a forward rotational direction or a reverse rotational direction, power outputted from the continuously-variable transmission. The reversing clutch device can be selectively switched, and the gear ratio can be steplessly changed by the continuously-variable transmission.
