PROBLEM TO BE SOLVED: To efficiently utilize a support structure of an operation lever, for accurately regulating an operation range of the operation lever.SOLUTION: A harvester comprises: an operation linkage mechanism H for transmitting a vibration operation of an operation lever 13 to a steering drive part and a lifting drive part and a pivotally support member 60 for supporting the operation lever 13 so as to freely vibrate around vibration shaft centers x1, y1 of a cross direction and a lateral direction. The pivotally support member 60 comprises a first rotation part 61 having the vibration shaft center y1 in one direction and a second rotation part 62 having the vibration shaft center x1 in the other direction. The first rotation part 61 has a regulation part 55 which is supported to a machine body fixing part rotatably around the vibration shaft center y1 in one direction, and regulates rotation of the second rotation part 62 around the vibration shaft center y1 in one direction following to rotation of the first rotation part 61, in a predetermined angle range.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】操作レバーの支持構造を有効利用して、操作レバーの作動範囲の規制を精度良く行えるようにする。【解決手段】操作レバー13の揺動操作を操向駆動部及び昇降駆動部に伝える操作連係機構Hと、操作レバー13を前後方向及び左右方向の揺動軸心x1,y1回りで揺動可能に支持する軸支部材60とを備え、軸支部材60は、一方向の揺動軸心y1を有した第1回動部61と、他方向の揺動軸心x1を有した第2回動部62とを備え、第1回動部61は一方向の揺動軸心y1回りで回動可能に機体固定部に支持され、第1回動部61の回動に伴う一方向の揺動軸心y1回りでの第2回動部62の回動を所定角度範囲内に制限する規制部55を備えている。【選択図】図6
