PROBLEM TO BE SOLVED: To surely perform the sliding and positioning fixation of an inside rail in a discharged straw-conveying apparatus where discharged straw after threshing processing is conveyed while being nipped with both of a conveying chain and nipping rails, the nipping rails are composed of an outside rail in charge of the starting end of conveyance and an inside rail slidably inserted in the outside rail and in charge of the terminal end of conveyance, and the terminal position in conveying the discharged straw with both of the conveying chain and the nipping rails can be changed and fixed. SOLUTION: The nipping rails are composed of a rail on the side of the starting end of conveyance and a rail on the side of the terminal end of conveyance which is slidably inserted in the rail on the side of the starting end of conveyance. A change between a position shortening a discharged straw- conveying distance and a position lengthening the discharged straw-conveying distance can be carried out by sliding the rail on the side of the terminal end of conveyance in such a way that every position can be fixed, and also a detent means for preventing the rotation of the rail on the side of the terminal end of conveyance when being slidden is installed.
