PROBLEM TO BE SOLVED: To provide a combine in which the number of revolution of a threshing cylinder can be quickly changed from a high speed state to a low speed state.SOLUTION: A transmission 20 is provided with: an input shaft 30 and an intermediate shaft 40 which extend in the right and left direction and to which an output rotation of an engine is transmitted； and an output shaft 60 which extends in the longitudinal direction and to which the rotation of the intermediate shaft 40 is transmitted. A second gear 33 is rotatably supported in the left side of the input shaft 30, and a recess 36 is formed in the right side of second gear 33. A mobile 35 movably supported in the right and left direction is provided in the input shaft 30.The mobile 35 is formed with a first gear 32, a recess 36 fitted with a protrusion 37 on the left hand side of the first gear 32, and a third gear 34 on the right side of the first gear 32. The intermediate shaft 40 is provided with a fourth gear 42 meshed with the first gear 32, a fifth gear 43 meshed with the second gear 33 on the left hand side of the fourth gear 42, and a sixth gear 44 meshed with the third gear 34 on the right side of the fourth gear 42.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】高速状態から低速状態に扱胴の回転数を迅速に変速できるコンバインの提供。【解決手段】変速装置２０に、エンジンの出力回転が伝動される入力軸３０と中間軸４０を左右方向に延在して設け、中間軸４０の回転が伝動される出力軸６０を前後方向に延在して設け、入力軸３０の左側部に、第２ギヤ３３を回転自在に支持し、第２ギヤ３３の右面に凹部３６を形成し、入力軸３０に左右方向に移動可能に支持された移動体３５を設け、移動体３５に第１ギヤ３２と、第１ギヤ３２の左側に凹部３６と嵌合う凸部３７と、第１ギヤ３２の右側に第３ギヤ３４を形成し、中間軸４０に第１ギヤ３２と噛合う第４ギヤ４２と、第４ギヤ４２の左側に第２ギヤ３３と噛合う第５ギヤ４３と、第４ギヤ４２の右側に第３ギヤ３４と噛合う第６ギヤ４４を設ける。【選択図】図５
