PROBLEM TO BE SOLVED: To provide a threshing structure of a general-purpose combine threshing device for promoting the flow of straw waste, smoothing the discharge to the rear in the axial direction of the shroud, and reducing the threshing load. SOLUTION: A spiral body 8 is configured to continuously and forcibly feed the end side of a handling barrel 3 in which handling teeth for grain-removing a grain culm supplied into a handling chamber 2 are continuously rearward in the axial direction.
