PROBLEM TO BE SOLVED: To make the positional relationship between a grip part and an operating switch easy to understand even without looking at an operating lever, thus facilitating operations with the thumb of a hand holding the operating lever in a state where operating errors are avoided.SOLUTION: At the grip part 40 of the operating lever that can be operated to move longitudinally, operating switches 42 for adjusting threshing depth are disposed on a horizontal side face 44A located on the drivers seat side in the horizontal direction. A recessed section 46 is provided on the rear face 45 side of the grip part 40 and near the horizontal side face 44A side where the operating switches are disposed. The recessed section 46 is so formed as to face the thenar eminence of the hand holding the grip part 40, so that the operating switches 42, 42 can be operated by the thumb.COPYRIGHT: (C)2013,JPO&INPIT【課題】操作レバーを目視しない状態でも握り部と操作スイッチとの相対的な位置関係を把握し易くして、操作レバーを把持した手の親指での操作を、誤操作の少ない状態で行い易くした。【解決手段】前後方向に移動操作可能な操作レバーの握り部40で、左右方向での操縦座席側に位置する横側面44Aに、扱き深さ調節用の操作スイッチ42を配設し、前記握り部40の後面45側で、かつ前記操作スイッチが配設されている横側面44A側寄りの箇所に凹入部46を設けてあり、この凹入部46は、親指による前記操作スイッチ42,42の操作を行うことが可能であるように前記握り部40を把持した手の母指丘部分と対向するように形成されている。【選択図】図4
