PROBLEM TO BE SOLVED: To provide a structure that a receiving net can easily be detached from an opening, when a threshing cylinder is opened, and prevents threshing performance deterioration and grain straw clogging generation caused by the structure. SOLUTION: In this thresher of a head-feeding combine harvester, a receiving net 3 curved along the outer periphery of a threshing cylinder 2 rotated on the first axis X1 is spanned over circular receiving net guides 13 disposed below both the front and rear portions of the threshing cylinder 2 on the downstream side of the rotation direction of the threshing cylinder 2, and when an upper case 15 is swung and upward moved with respect to a lower case 14 on the second axis X2, the receiving guides 13 can be detached from the formed opening H. Therein, the receiving net 3 has a two-dividable structure which can be divided into an upper side receiving net portion 3A placed on the upstream side of the threshing cylinder 2 in the rotation direction and into a lower side receiving portion 3B placed on the downstream side of the threshing cylinder 2 in the rotation direction. A support member 18 for receiving and supporting the division ends 3a, 3b of the receiving net portions 3A, 3B is spanned over the front and rear receiving net guides 13.
