<P>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. <P>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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
