PROBLEM TO BE SOLVED: To solve the problem of difficulty caused by undesirable operability because, when fixing two discharging cylinders by winding a rubber band on folded discharging cylinders at the time of housing in a conventional folding type discharging auger, the operation is carried out at a high position of the upper part of a threshing device. SOLUTION: This discharging auger 3 in a combine harvester 2 has a tip discharging cylinder 7 having a grain-discharging opening 6 opened at the tip part, and joined to a base discharging cylinder 5 joined to the upper part of a grain-lifting cylinder 4 at the base part so as to be freely folded. A bracket 8 and a lock pin 9 freely detachably engaging with the bracket 8 are installed in one side and the other side of the outer periphery of the tip discharging cylinder 7 and the position of the outer periphery of the base discharging cylinder 5 corresponding thereto when folding the tip discharging cylinder 7, respectively. The lock pin 9 is fixed by a hair pin 10 in the engaging state with the bracket 8.
