PROBLEM TO BE SOLVED: To simplify a positional switching operation of a grain tank in spite of the one swinging and driving a flow guiding plate by a power from a transmission system extended from an engine to a bottom screw. SOLUTION: This transmitting structure is configured by forming the transmission system 16 extended from the engine installed into a running machine to the bottom screw 8 into a shaft transmitting structure facing the left and right sides, comprising an engaged and disengaged clutch 17C linked with the posture change of the grain tank 7, connecting a transmission shaft 17B on the downstream side of the clutch 17C in the transmitting direction and the bottom screw 8 with a bevel gear-style transmission mechanism 19 so as to be interlocked and installing a cam mechanism 26 swinging and driving the flow guiding plate around the center of a back and forth axis accompanied with driving of the bottom screw 8 between a shaft supporting part 25 for supporting the bottom screw 8 linked with a front wall 7A of the grain tank 7 and the bevel gear-style transmission mechanism 19 in the shaft transmitting structure.
