PROBLEM TO BE SOLVED: To provide the subject structure afforded with a sorting wind channel for feeding sorting wind going from below the grain pan to above to a treated product fed from a grain pan to a chaff sieve to enable the treated product to be sorted in relatively high accuracy even in case the specific gravity-based sorting operation in the grain pan is inadequate. SOLUTION: This sorting section structure in a threshing apparatus mounted with a grain pan 13 and a chaff sieve 14, is so designed that, the grain pan 13 is set up in such a way that a treated product platform surface on the transfer direction terminal end of the grain pan 13 is bent against that on the transfer direction initial end and runs to a slope situated at higher level toward the transfer direction terminal end 13a, and a sorting wind channel 16 is provided so as to feed sorting wind going from below the grain pan 13 to above to a treated product fed from the grain pan 13 to the chaff sieve 14.
