PROBLEM TO BE SOLVED: To solve a problem such that in especially a multiple rows-reaping type combine, sometimes a large amount of threshed grains are conveyed into a selecting device at the same time, and in such case, the selection treatment can not be sufficiently performed. SOLUTION: This threshing device consisting of a threshing part 12 and a selecting part 17 is provided by installing a feed pan 30 for receiving the treated materials leaking down from a receiving net 20 of the threshing part 12, a chaff sieve 33 which is a coarse selecting part for selecting the treated materials from the feed pan 30, and a grain sieve 32 which is a fine selecting part for further selecting the treated materials leaking down from the coarse selecting part at the selecting part 17, and also arranging a fanning mill 26 for sending selection wind into the shaking main body 49 in the lower direction of the feed pan 30, installing a sieving device 54 in the lower direction of the receiving net 20 and between the feed pan 30 and the chaff sieve 33, and a sieving device 53 in the rear lower direction of a threshing drum 21 and on an extended line and in a rear direction of the receiving net 20, and further making these sieving devices 53, 54 shake by receiving the shake of the shaking main body 49.
