PROBLEM TO BE SOLVED: To provide a combine in which a structure around a reaper input shaft is simplified, while enabling normal-reverse rotation drive of a reaping device.SOLUTION: A combine is characterized by: providing an intermediate shaft (41) where the driving force of an engine (20) is input, in a sorting drive unit (36)； providing a normal rotation drive unit (S) for transmitting the rotation in the same direction as the intermediate shaft (41) to a reaper input shaft (22) included to the rearward of a conveyance elevator (14), and a reverse rotation drive unit (G) for transmitting the rotation in the reverse direction to the intermediate shaft (41) to the reaper input shaft (22)； and including an intermediate pulley (42) included in the intermediate shaft (41), a first pulley (43) of a first conveyor (18), and a reverse rotation pulley (46) coming into contact from a front side to an outer circumference of the belt wound around a second pulley (44) of a second conveyor (19) and rotating in the reverse direction to the intermediate pulley (42), in the reverse rotation drive unit (G).SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】刈取装置を正逆転駆動可能としつつ、刈取入力軸周辺の構造を簡素化したコンバインを提供する。【解決手段】選別駆動部（３６）には、エンジン（２０）の駆動力が入力される中間軸（４１）を設け、中間軸（４１）と同方向の回転を搬送エレベーター（１４）の後部に備える刈取入力軸（２２）に伝達する正転駆動部（Ｓ）と、中間軸（４１）とは逆方向の回転を刈取入力軸（２２）に伝達する逆転駆動部（Ｇ）を設け、逆転駆動部（Ｇ）には、中間軸（４１）に備える中間プーリー（４２）と一番コンベア（１８）の一番プーリー（４３）と二番コンベア（１９）の二番プーリー（４４）に掛け回したベルトの外周に前側から接触して、中間プーリー（４２）とは逆方向に回転する逆転プーリー（４６）を備える。【選択図】図８
