PROBLEM TO BE SOLVED: To satisfy both of improvement in maintenance workability and improvement in support strength of grain culm raising device 31 in a combine harvester. SOLUTION: The combine harvester includes the grain culm raising device 31 having a plurality of raising cases 42 positioned in a laterally aligned state at the front of a reaping device 3. Gear cases 41 installed at the back side of each of the raising cases 42 and a plurality of raising horizontal pipes 40 for mutually connecting the adjacent gear cases 41 are alternately arranged on the upper side of the group of the raising cases 42. Each of the raising horizontal pipes 40 is supported on the reaping upper frame 121 of the reaping device 3. Each of the gear cases 41 is detachably connected to the adjacent raising horizontal pipes 40 so that a fixing phase is changeable in a vertical direction around a horizontal central axis of the group of the raising horizontal pipes 40 and the group of the gear cases 41 and the group of the raising horizontal pipes 40 are constituted as strength members to each of the raising cases 42.
