PROBLEM TO BE SOLVED: To automatically and surely control the dust feed amount by using a dust feed guide having a simple and inexpensive constitution, in a threshing apparatus of a combine harvester equipped with the dust feed guide for controlling the dust feed amount while holding a treated material in a threshing chamber by bringing the treated material flowing through the interior of the threshing chamber into contact with the inner side of a threshing cylinder cover forming the threshing chamber. SOLUTION: In the threshing apparatus, dust feed guides 16 and 16' each composed of an elastic material which is deformable in the direction increasing the dust feed amount when flowing amount of the treated material in the threshing chamber 11 is increased are installed on the inner side of a threshing cylinder cover 15 forming the threshing chamber 11.
