PROBLEM TO BE SOLVED: To adjust endless rotating bodies of an adjoining pair of crop-grabbing/conveying devices to an equal tension state with simple operation.SOLUTION: There are provided: a start-end rotating wheel body 52 around which the conveyance-start end of the endless rotating body 55 of one of a pair of crop-grabbing/conveying devices 45, 45 adjoining in the machine body lateral direction winds in a state that returning paths 59 of the endless rotating bodies 55 face each other a movable support member 84 at a start-end rotating wheel body 52 where the conveyance-start end of the endless rotating body 55 winds and support elements 82 at a fixing side freely movably supporting the support elements 84 at the movable side. There is further provided a tensioning means 85 performing the moving operation to the movable support member 84 at the movable side against the support member 82 at the fixing side in a direction whereby tension is applied to the endless rotating bodies 55 of the pair of crop-grabbing/conveying devices 45, 45 via the start-end rotating wheel bodies 52.COPYRIGHT: (C)2013,JPO&INPIT【課題】隣り合う一対の収穫物係止搬送装置の無端回動体を操作簡単に等しい張力状態に調整できるようにする。【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の一方における無端回動体55の搬送始端側が巻回する始端側回転輪体52、及び他方における無端回動体55の搬送始端側が巻回する始端側回転輪体52を支持する可動側支持部材84と、この可動側支持部材84を移動自在に支持する固定側支持部材82とを備えてある。一対の収穫物係止搬送装置45,45における無端回動体55に始端側回転輪体52によって張力付与する方向に可動側支持部材84を固定側支持部材82に対して移動操作する張力付与手段85を備えてある。【選択図】図17
