To maintain the good threshing performance by preventing a treated product from flowing backward to a threshing cylinder side at the feeding position from a second product-lifting cylinder of a second product-threshing cylinder in a threshing apparatus having a threshing cylinder and the second product-threshing cylinder parallelly arranged in a threshing chamber, and feeding the second product leaked down from the rear part of a swinging selection shelf at the lower side of the threshing chamber to the second product-treating cylinder.
The threshing apparatus 15 is constituted by surrounding the threshing cylinder 69 axially supported in the threshing chamber 66 with a threshing net 74, and axially supporting the second product-threshing cylinder 70 so as to neighbor to the threshing net 74, to feed the treated product dropped from the swinging selection shelf 51 at the lower part of the threshing cylinder 69, to the second product-threshing cylinder 70 side by a second product-lifting cylinder 87. A screen wall 61 for preventing the treated product from flying out to the threshing cylinder 69 side is installed in the feeding position of the second product-lifting cylinder 87 to the second product-treating cylinder 70.
