PROBLEM TO BE SOLVED: To provide an attitude-holding device of an inter-ridge working machine, which can stably hold the attitude of the machine frame of the inter-ridge working machine.SOLUTION: In this inter-ridge working machine, equipped with an auxiliary wheel, separately disposed at the front or back of the machine frame B from driving wheels to determine the front and rear heights of the machine frame, a substantially horizontally projected horizontal support portion 5 is fixed to the middle height site of a vertical support pipe Bb, having the auxiliary wheel Ba mounted thereon via an attaching portion 6 a lateral fixing pipe 54 having both the laterally directed ends to the tip portion of the horizontal support portion 5 is fixed at its middle laterally movable pipes 53 having roller-attaching brackets 2 thereunder are fixed onto the lateral fixing pipe 54, in a state of being fixed or capable of being slid laterally or fixed and the rotation support shafts 12 of longitudinally long guide rollers 1 are fixed at the upper end portions such that the guide rollers 1 freely rotatable under the right and left roller-attaching brackets 2 are set to have a width between the right and left circumferential surfaces substantially equal to the inter-ridge distance and the angle is formed to have the whole circumferential surface widths of the guide rollers 1 contact with both the inter-ridge side surfaces.COPYRIGHT: (C)2008,JPO&INPIT【課題】畝間作業機の機体の姿勢を安定して保持できる装置を提供する。【解決手段】機体Bの前部又は後部に駆動車輪から離れて配設されて機体の前後の高さを決める補助輪Baを備えた畝間管理機において、前記補助輪Baを装着した縦支持パイプBbの中間高さ部位に、略水平に突出させた水平支持部5を取付部6を介して固定できるようにし、前記水平支持部5の先端部に両端を左右側方に向けた左右固定パイプ54をその中間部位で固定し、前記左右固定パイプ54に、下部にローラ取付けブラケット2を備えた左右可動パイプ53をそれぞれ固定又は左右スライド調節及び固定可能に挿着し、前記左右のローラ取付けブラケット2の下にそれぞれフリー回転する縦長なガイドローラ1を、その左右の周面間の幅が畝間の間隔とほぼ同一となって両畝側面にガイドローラ1の周面全幅が当接可能な角度になるように前記ガイドローラ1の回転支持軸12をその上端部で固定する。【選択図】図1
