PROBLEM TO BE SOLVED: To make it easy to avoid or suppress the generation of tension force difference of an endless turning bodies between adjacent harvestry locking conveying devices.SOLUTION: Tension force adjusting unit 80 providing tension force to endless turning bodies 55 of a pair of harvestry locking conveying devices 45, 45 adjacent in a machine lateral direction with return passages 59 of the endless turning bodies 55 facing each other are arranged. A balance supporting body 81 to which one starting end side rotation wheel body 52 supporting a conveying supporting end of the endless turning body 55 in one of the pair of harvestry locking conveying devices 45, 45 and the other starting end side rotation wheel body 52 supporting a conveying starting end of the endless turning body 55 in the other are rotatably coupled and a frame side supporting body 84 supported by frame sides of the pair of harvestry locking conveying devices 45, 45 with balance supporting body 81 oscillatably coupled are arranged. |
