PROBLEM TO BE SOLVED: To provide a combine harvester capable of conveying grains by a low conveyance torque, and maintaining high grain-conveying capacity. SOLUTION: The combine harvester is equipped with a horizontal screw 3 at the bottom part of a grain tank 2 over the front and rear direction of a machine body, and a regulation plate 1 in an umbrella shape in the cross section view, arranged at the upper part thereof. The regulation plate 1 is supported by a regulation plate supporting shaft 4 and formed so that the upstream side 1b of the conveyance may be narrower and the downstream side 1a of the conveyance may be wider. As a result, the interval B between the terminal edge part of the regulation plate 1 at the upstream side 1b of the conveyance and the tilted face 2a of the grain tank 2 is made wider to allow a large amount of the grain to flow down, and the interval A at the downstream side 1a of the conveyance is made narrower to control the flowing down of the grain.
