To solve the problem that, when using a combine for an extended period, a maintenance work is required, for removing threshed objects accumulated inside by opening a threshing chamber.SOLUTION: A thresher is provided with a selection chamber (20) for sending blast of a fan on a receiving net (12) lower part of a threshing chamber (10) supporting pivotally a threshing cylinder (11), and with a flow-down guide (40) for guiding threshed objects into the selection chamber (20), on the inside cover (43) of the threshing chamber (10). In the thresher, the flow-down guide (40) is constituted of a flow-down guide part (50a) inclined downward into the selection chamber (20), and a blowup part (50b) for guiding blast of the winnower fan toward the receiving net (12) on a lower part of the flow-down guide part (50a).SELECTED DRAWING: Figure 2【課題】コンバインを長時間使用すると、扱室を開放して内部に堆積した脱穀物を取り除くメンテナンス作業が必要となる。【解決手段】扱胴（１１）を軸支した扱室（１０）の受網（１２）下部に唐箕の送風を送る選別室（２０）を設け、前記扱室（１０）の内側カバー（４３）に脱穀物を前記選別室（２０）にガイドする流下ガイド（４０）を設けた脱穀装置において、前記流下ガイド（４０）を前記選別室（２０）内に下り傾斜する流下案内部（５０ａ）と該流下案内部（５０ａ）の下部で前記唐箕ファンの送風を前記受網（１２）に向けて誘導する吹上部（５０ｂ）で構成したことを特徴とする脱穀装置とする。【選択図】図２
