PROBLEM TO BE SOLVED: To provide a grain transportation apparatus for a combined harvester in which a rotation gear is installed in a vertical transportation cylinder for discharging grain to the outside of the machine, a motor gear is axially supported on a rotational motor of a motor bracket for revolving the vertical transportation cylinder, engagement of the motor gear with a rotation gear is made certain and the rotations of the vertical transportation cylinder and a discharge auger set at the top part of the vertical trans portation cylinder are smoothed. SOLUTION: This grain transportation apparatus for a combined harvester has a constitution in which the vertical transportation cylinder 5 for discharging grain to the outside of a machine and the discharge auger 8 at the top of the vertical transportation cylinder 5 are installed, the rotation gear 25 of the vertical transportation cylinder 5 is engaged with the motor gear 26 axially supported on the rotational motor 27 of the motor bracket 28 so that the vertical transportation cylinder 5 can be rotated. A boss 26a part of the motor gear 26 is axially supported on the motor bracket 28, a fixed number of teeth 25a of the rotation gear 25 are removed, the rotation is stopped, a rotation range is controlled and a control plate 29 is set to stop the vertical transportation cylinder in a rotation range.
