The lower portion of the retreating device 59 communicates with the threshing device 5 through a tailings-releasing portion 215 arranged below the rotation shaft 158 of a threshing cylinder 51 in the threshing device 5. The lower portion of the retreating device 59 is connected to the rear upper side of the tailings-releasing portion 215. COPYRIGHT: (C)2011,JPO&INPIT
