PROBLEM TO BE SOLVED: To provide an inter-ridge guide which can automatically guide a farm working vehicle in a central direction between ridges even in a field having curved ridges, can thereby farm without anxiety and without damaging the ridges with tires, and can easily change the travel direction of the farm working vehicle.SOLUTION: The inter-ridge guide of the farm working vehicle is characterized by forward projectedly disposing a support piece 9 having a pivoting portion 10 at a tip 9a, on the tip lower portion 1c of a vehicle body 1, vertically openably and movably pivoting an arm-like shaft 11 having right and left wheel-bearing portions on both the obliquely front sides on the pivoting portion 10, laterally symmetrically obliquely and rotatably mounting right and left guiding wheels 14, 15 on both right and left wheel-bearing portions 12, 13 of the arm-like shaft 11 so that the right and left guiding wheels 14, 15 are opened in a downward-opened form on the front view, when the arm-like shaft 11 is downward directed, and setting the arm-like shaft 11 in such a length that the right and left wheel-bearing portions 12, 13 are forward placed at an angle of about 45 degree from the right lower direction of the pivoting portion 10 of the support piece to a front lower direction on the side view.COPYRIGHT: (C)2008,JPO&INPIT【課題】 曲線的な畝の農地でも、農作業車を畝間の中央方向に自動的に誘導し、タイヤで畝を傷付けることのなく安心して農作業ができ、且つ農作業車の方向転換も容易に行える畝間誘導装置を提供する。【解決手段】 車体1の最先端下部1cに、先端9aに枢支部10を備えた支持片9を前方に向けて突設し、該枢支部10に両斜め前側方に車輪軸受部を有する左右の腕状軸11を上下擺動可能に枢支し、該腕状軸11の両車輪軸受部12、13に、左右の誘導車輪14、15を、腕状軸11が下向き状態のときに、左右の誘導車輪14、15が正面から見て下開きのハ字型になるように左右対称に傾斜させて回転フリーに装着する。前記腕状軸11は、側面から見た車輪軸受部12、13の位置が支持片の枢支部10の真下方向から前下方へ約45度までの範囲内の前方下がり角度となる長さに設定する。【選択図】 図1
