PROBLEM TO BE SOLVED: To provide a portable bush cutter for the bush-cutting work at an optimal angle according to various working environments and working conditions, and for relieving the fatigue of a worker.SOLUTION: The bush cutter is a back pack bush cutter. In the bush cutter, an operation handle 4 has such a shape as to extend to the right and left from a position where an outer pipe 23 is fixed, and after that, bend upward and extend upward at 20 degrees to the front and to the rear respectively from the vertical direction in the direction of separating from the outer pipe in the range of 30 degrees from the vertical direction to make grips, and after that, bend backward and extend rearward at 20 degrees above and below respectively from the horizontal direction in the direction of separating to a frame pipe 3 in the range of 45 degrees from the horizontal direction parallel to the outer pipe 3 to make the grips, and after that, bend downward and extend rearward at 20 degrees to the right and to the left respectively from the vertical direction in the range of 45 degrees from the vertical direction to make grips.COPYRIGHT: (C)2012,JPO&INPIT【課題】携帯用刈払機において、様々な作業環境や作業状況に応じ最適な角度での刈払い作業および作業者の疲労を軽減する器具を提供する。【解決手段】背負い式刈払機であり、操作ハンドル4はアウターパイプ23の固定位置からそれぞれ左右に延びた後、上方に屈曲して垂直から前後に各20度で垂直から30度の範囲で該アウターパイプから離れる方向に上方に延びグリップ部となった後、後向きに屈曲して略水平から上下に各20度で該アウターパイプ3と平行から45度の範囲で該フレームパイプ3に離れる方向の後方に延びグリップ部となった後、下方に屈曲して垂直から各左右20度で垂直から45度の範囲で後方に延びてグリップ部となる形状を有することを特徴とする。【選択図】図13
