PROBLEM TO BE SOLVED: To provide a threshing device settled a problem that, when gathering grain culm in a field with a combine harvester, in a case harvesting under a high humidity, the grain culm adheres to a transporting part and a screening part to form a stack and, thereby, transport failure at the transporting part and insufficient separation at the separating part are caused, so screening failure happens and degradation of threshing performance and threshing operation efficiency are caused. SOLUTION: This threshing device for a combine harvester has a threshing chamber 2 and a screening chamber 7 above and below, wherein the threshing chamber 2 has a threshing cylinder 1 and the screening chamber 7 has a transporting part A having projections 3 formed a slant on their upper surface and, following thereto, a swinging screening rack 6 comprising a screening part B having a number of plates 4 by a specific space and forming passages 5 vertically communicating between the plates. And also the threshing device for the combine harvester has a heater 8 heating the lower surface of the transporting part A, the screening part B or both of the transporting part A and the screening part B of the swinging screening rack 6.
