PROBLEM TO BE SOLVED: To provide the grain-discharging apparatus of a combine harvester, which enables the extension of a discharging distance, the expansion of a grain-discharging port position-changeable range, the downsizing of a machine frame, and the improvements in the operability and workability of a discharging auger. SOLUTION: This grain-discharging apparatus of the combine harvester is manufactured by attaching the base portion of a horizontal discharging auger 6 having the auger grain-discharging port 18 to the upper portion of a vertical grain-elevating apparatus 5 for discharging grains in a grain tank 4, wherein the auger grain-discharging port 18 can be rotated on the vertical axis of the vertical grain-elevating device 5 and can further vertically be rotated on an arbitrary horizontal axis near to the vertical grain-elevating device 5, disposing a bending portion 10 capable of being bent and rotated on a vertical axis P in the intermediate portion of the horizontal discharging auger 6, and further disposing an auger tip discharging portion 20 having the auger grain-discharging port 18 at the tip of a movable auger 9 capable of being bent and rotated on the vertical axis P of the bending portion 10, wherein the auger tip discharging portion 20 is formed by disposing the auger grain-discharging port 18 at the tip of a discharging cylinder portion 28 disposed in a state capable of being longitudinally rotated on a horizontal axis S3 at the tip of the movable auger 9.
