To solve the problem that, in a conventional configuration, a seal member is provided in an operation groove of a main speed change lever, and deterioration in the seal member by a lever operation cannot be avoided so that an internal mechanism cannot be protected due to abrasion and damage of the seal.SOLUTION: A combine includes a traveling device 2 driven by the rotation of an engine, a reaping device 4, a thresher 3, and a steering part 6 for operating these. A front operation part 12 is provided on the front side of a seat 10 of the steering part 6, and a side operation part 11 is provided on the side of the seat 10. A main speed change lever 15 is provided on the side operation part 11 for executing a speed change operation for a machine body traveling speed. The main speed change lever 15 is configured so as to move in a front-back direction with respect to a panel plate 20 of the steering part 6 by a rail member 23 provided on the steering part 6. A detection device 21 is provided on the rail member 23 for detecting a front-back moving position of the main speed change lever 15. A seal member 60 for closing a lever moving groove 17 of the panel plate 20 is configured in the main speed change lever 15 so as to move integrally with the front-back movement of the main speed change lever 15.SELECTED DRAWING: Figure 4
【課題】従来、主変速レバーの操作溝にシール部材を設けているので、レバー操作によるシール部材の劣化が防げず、シールが摩耗したり破損したりし、内部機構を保護できなくなることがあった。【解決手段】エンジン回転により駆動する走行装置2と、刈取装置4と脱穀装置3とを夫々設け、これらを操作する操縦部6を設け、操縦部6の座席10の前側には前側操作部12を、座席10の側部には側部操作部11を、夫々設け、側部操作部11には、機体走行速度の変速操作を行う主変速レバー15を設け、主変速レバー15は操縦部6に設けたレール部材23により操縦部6のパネル板20に対して前後方向に移動する構成とし、レール部材23には主変速レバー15の前後移動位置を検出する検出装置21を設け、主変速レバー15にパネル板20のレバー移動溝17を閉塞するシール部材60を、主変速レバー15の前後移動と共に一体移動するように構成したコンバイン。【選択図】 図4
