<P>PROBLEM TO BE SOLVED: To provide a portable working machine capable of achieving a method for easily fixing a vibration insulating device member and a power unit, reducing the number of components, and facilitating the assembly. <P>SOLUTION: The portable working machine includes an engine, a frame 3 which holds the engine, a front handle 5 which is fixed to the frame 3, and a power conversion part (6) which transmits the output of the engine to drive a working implement. A vibration insulating device 20 is composed of a spring 21, and is disposed in such a way that the center of an attaching position of the front handle 5 approximately coincides with an axis of the spring 21. The spring 21 is wound counterclockwise, and a spring holder 22 is fixed by bolts 30 for fixing the front handle 5. As the spring holder 22 is pressed on the frame 3 with the action of the counterclockwise spring 21 when the bolts 30 are tightened, the front handle 5 and the vibration insulating device 20 can be simultaneously fixed only by tightening the bolts 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
