PROBLEM TO BE SOLVED: To obtain optimum anti-vibration effects in suiting to the situations of a brush cutter body through adjusting the deflection level of a vibration-proof material.SOLUTION: A portable brush cutter is provided, being such that: the tip of a pole is set with a working part such as a cutter an engine for driving the working part and throttle wires 8 for putting the operation of the engine under control are laid the basal part side of the pole is installed with a lever enabling itself to make a returnable control and the working part and the engine are connected by a transmission shaft with each other. In this brush cutter, the pole is disposed with support members supporting the lever via respective vibration-proof materials 12 on both sides of the lever both sides of the lever are furnished with respective projections 14 projected in the direction of the pole axis each of the vibration-proof materials 12 is provided with an opening groove to be inserted with each of the corresponding projections 14 and each of the support members is provided with a recessed part to be housed with each of the corresponding vibration-proof materials 12 and also provided so as to nip the relevant vibration-proof material 12 in the axial direction of the pole with both the support member and the lever.COPYRIGHT: (C)2012,JPO&INPIT【課題】防振材の撓み量を調整して、刈払い機本体の状況に合わせて最適な防振効果を得る。【解決手段】棹の先端にカッター等の作業部を設け、作業部を駆動するエンジンとエンジンの作動を制御するスロットルワイヤ8を引き、戻し操作可能なレバー装置を棹の基部側に設け、作業部とエンジンとを伝動軸で連結する携帯型刈払い機において、棹には、レバー装置の両端に防振材12を介してレバー装置を支持する支持部材を配置し、レバー装置の両端に棹軸方向に突出した突起部14を設け、防振材12には上記突起部14が挿入される開口溝を設け、支持部材には、防振材12を収納する収納凹部を設けるとともに、支持部材とレバー装置とで防振材12を棹の軸方向で挟み込むように取り付けた。【選択図】図2
