PROBLEM TO BE SOLVED: To provide a threshing device that can prevent grain from being discharged abundantly to become a loss while reducing a processing load of a chaff sieve.SOLUTION: A threshing device includes a threshing cylinder 6 rotationally driven and threshing crops, a threshing concave 7 provided below the threshing cylinder 6, and a swinging sorter 16 for sorting and processing the processed product coming down from the threshing concave 7 while transferring it. The swinging sorter 16 includes a grain pan 25 positioned at a starting-edge side in a transfer direction, sieve lines 27, 28 positioned at a downstream side in the transfer direction of the grain pan 25, and a chaff sieve 29 extending from a lower side place of the sieve lines 27, 28 toward the downstream side in the transfer direction. A guide plate 50 is included on an upper side of the chaff sieve 29, the guide plate that moves and guides the processed product swung and transferred over the chaff sieve 29 from an upstream side to a downstream side in a threshing cylinder rotation direction in a width direction of the chaff sieve 29.SELECTED DRAWING: Figure 1 【課題】チャフシーブの処理負担を軽減しながら、穀粒が多量に排出されて損失になることを回避できるようにする。【解決手段】回転駆動されて作物を扱き処理する扱胴６と、扱胴６の下方に設けられた受網７と、受網７から下方に漏下した処理物を移送しながら選別処理する揺動選別装置１６とが備えられ、揺動選別装置１６は、移送方向始端側に位置するグレンパン２５と、グレンパン２５の移送方向下手側に位置する篩い線２７，２８と、篩い線２７，２８の下方側箇所から移送方向下手側に向けて延びるチャフシーブ２９とが備えられ、チャフシーブ２９の上部側に、チャフシーブ２９上を揺動移送される処理物を、チャフシーブ２９の幅方向において扱胴回転方向上手側から下手側へ移動案内する案内板５０が備えられている。【選択図】図１
