PROBLEM TO BE SOLVED: To provide a grain dispensing apparatus of a combine harvester having a compact-sized discharging port of the grain dispensing apparatus and its surroundings by reducing the size of a shutter driving device placed at the discharging port. SOLUTION: The shutter driving device 5 is constructed of an opening and closing electric motor 50 as a driving force source, and an operation mechanism 6 to open and close the shutter 46 by transmitting the driving force of the opening and closing electric motor 50 to the shutter 46. The operation mechanism 6 is provided with a rotary cam 60 driven by the rotation driving force of the opening and closing electric motor 50, the rotary cam 60 is rotated to form a transfer orbit along a lateral shaft of the shutter 46, and the shutter 46 is driven by sliding contact with the cam surface of the rotary cam 60.
