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.COPYRIGHT: (C)2014,JPO&INPIT【課題】隣り合う収穫物係止搬送装置どうしの間における無端回動体の張力差発生を回避や抑制し易くする。【解決手段】無端回動体55の戻り経路59が対向し合う状態で機体横方向に隣り合う一対の収穫物係止搬送装置45,45の無端回動体55に張力を付与する張力調整手段80を設けてある。一対の収穫物係止搬送装置45,45の一方における無端回動体55の搬送始端側を支持する一方の始端側回転輪体52及び他方における無端回動体55の搬送始端側を支持する他方の始端側回転輪体52が回転自在に連結された天秤支持体81と、天秤支持体81が揺動自在に連結された状態で一対の収穫物係止搬送装置45,45のフレーム側に支持されるフレーム側支持体84とを備えてある。【選択図】図6
