PROBLEM TO BE SOLVED: To divide a ROPS frame into a lower ROPS frame and an upper ROPS frame and perform a firm bolt fastening during assembly.SOLUTION: In a ROPS frame of a tractor, nuts are welded to an inside surface at an inner part of a rectangular tube in a vertical juncture part between a bilaterally lower ROPS frame 32, 32 and an upper ROPS frame 33, and fitted with a U-shaped plate 37 consisting of a frontside plate, a backside plate, a bilateral inside plate which is U-shaped in a plan view. A plate thickness of the U-shaped plate 37 is thinner than those of the rectangular tube used as the lower ROPS frame 32, and the upper ROPS frame 33. The ROPS frame is sandwiched by the frontside plate, the backside plate, the bilateral inside plate of the bilateral connection recess 35a, 35a and the frontside plate, the backside plate, the bilateral inside plate of the U-shaped plate 37 and fastened by a bolt.SELECTED DRAWING: Figure 6
【課題】ロプスフレームを下部ロプスフレームと上部ロプスフレームに分割し、組み付け時に強固にボルト締結する。【解決手段】左右下部ロプスフレーム32,32と上部ロプスフレーム33の上下接合部における角チューブ内側部位にナットを内側面に溶着し且つ前側板,後側板,左右内側板からなる平面視U字型のU字型プレート37を嵌合し、U字型プレート37の板厚を下部ロプスフレーム32,上部ロプスフレーム33の角チューブの板厚よりも薄く構成し、左右連結凹部35a,35aの前側板,後側板,左右内側板とU字型プレート37の前側板,後側板,左右内側板で挟みボルト締結したことを特徴とするトラクタのロプスフレームとする。【選択図】図6
