PROBLEM TO BE SOLVED: To provide a grain unloading device of a combine harvester, which is capable of smoothing the expansion and contraction of a lateral unloading auger by devising the position of a contacting roller. SOLUTION: In this grain unloading device of the combine harvester, the lateral unloading auger 6 connected with a vertical cereal grain-lifting device 5 for unloading the cereal grains in a grain tank 4 is separated to a fixed auger 7 connecting with the vertical cereal grain-lifting up device 5 and a moving auger 8 slidably attached with the fixed auger 7, the moving auger 8 is configured as slidable by a motor 23 for driving the expansion and contraction, an upper abutment roller 47 abutting on the upper side inner circumferential surface of the moving auger 8 is provided at an intermediate side bearing part 11 installed at the end of the fixed auger 7, and a lower side-contacting roller 48 abutting on the lower surface of outer circumference of the fixed auger 7 is provided at the base part of the moving auger 8.
