PROBLEM TO BE SOLVED: To excellently maintain a driving gear for driving an unloading auger to improve workability and to accurately and readily connect the driving gear to the power transmission part of the unloading auger in a combine harvester that is equipped with the unloading auger for unloading grain in a grain tank and with which the unloading auger has a horizontal spiral for conveying the grain in the grain tank in the horizontal direction and a vertical spiral for upward conveying the grain from the horizontal spiral and both the spirals are interlocked by a power transmission device. SOLUTION: The combine harvester is equipped with the driving gear for driving the unloading auger and the driving gear has an unloading motor and a transmission shaft and the transmission device for transmitting power to the vertical spiral. The transmission shaft and the transmission device are rotatably supported in a base to form a unit structure. The integrated driving gear is installed from the under side of a machine body frame and the projected part of the transmission shaft is connected to a connection part interlocked to the vertical spiral. A transfer case below the vertical spiral has a supporting boss at its under side and the projected part of the driving gear is engaged with the inner peripheral surface of the supporting boss.
