To provide a combine that facilitates position adjusting work for making position change of an upstream side rotary shaft in the conveyance direction in a threshed straw conveying device.SOLUTION: A combine includes a position adjusting mechanism 42 where multiple endless turning bodies 26 are wound over a downstream side wheel and an upstream side wheel 25, and capable of position change of an upstream side rotary shaft 24 for supporting the upstream side wheel 25 along the conveyance direction. The position adjusting mechanism includes: an adjusting screw shaft 53 extending along the conveyance direction； a connection part 54 for connecting an adjusting screw shaft 53 and a rotary shaft support 41； a regulation guide part 56 having an insertion part where the adjusting screw shaft 53 is inserted in a movable manner； a nut 57 mounted to the adjusting screw shaft 53； and a compression spring 58 externally inserted to the adjusting screw shaft 53 over the nut 57 and the regulation guide part 56. The connection part 54 is positioned at the side opposite to the compression spring 58 with respect to the regulation guide part 56.SELECTED DRAWING: Figure 4【課題】穀稈搬送装置において、上手側回転軸を搬送方向に位置変更させる位置調節作業を容易に行えるコンバインを提供する。【解決手段】下手側輪体と上手側輪体２５とにわたって複数の無端回動体２６が巻回され、上手側輪体２５を支持する上手側回転軸２４を搬送方向に沿って位置変更可能な位置調節機構４２に、搬送方向に沿って延びる調節用ネジ軸５３と、調節用ネジ軸５３と回転軸支持体４１とを連結する連結部５４と、調節用ネジ軸５３が移動可能に挿通する挿通部を有する規制案内部５６と、調節用ネジ軸５３に装着されたナット５７と、ナット５７と規制案内部５６とに亘る状態で調節用ネジ軸５３に外挿された圧縮バネ５８と、が備えられ、連結部５４が規制案内部５６に対して圧縮バネ５８とは反対側に位置している。【選択図】図４
