PROBLEM TO BE SOLVED: To enable conveying cylinders to be connected so as to be relatively turned by a simple structure without requiring a single purpose component such as an engaging metal fitting in a screw-type grain conveyor obtained by connecting the end terminal part of the conveying cylinder in a first screw-type conveying structure with the starting terminal part of the conveying cylinder in a second screw-type conveying structure so as to be relatively turned around mutually orthogonal fulcrum axis centers, and interlocking and connecting the end terminal of a screw installed in the conveying cylinder of the first conveying structure, and the starting terminal of a screw installed in the second conveying structure with a transmission shaft arranged along the fulcrum axis centers. SOLUTION: The subject screw-type grain conveyor is constituted by fitting and connecting the end terminal part of the conveying cylinder in the first conveying structure with the starting terminal part of the conveying cylinder in the second conveying structure so as to be relatively turned around the fulcrum axis centers, so that both of the conveying cylinders may be prevented from being separated in the fulcrum axis direction by the transmission shaft and bevel gears installed in both terminals thereof.
