PROBLEM TO BE SOLVED: To provide the handle supporting structure of a hand-held power working machine, which controls an increase in weight and has excellent vibration insulation and operability. SOLUTION: A hedge trimmer 1 is equipped with a front handle 40 attached to the rear of a supporting member 10. The handle is supported by a first to a third supporting arms 45, 50 and 55 extended in the longitudinal direction. The connection positions of tip parts of the supporting arms are flatly arranged and connected through vibration-proof members 46, 51 and 56. The length of each supporting arm is longer than a length between the position of the thumb Ht of an operator's hand grasping the handle and a handle base end part and a straight line L connecting the connection position 47 of the first supporting arm 45 to that of the second supporting arm 50 is passed through the handle in a plane view. The vibration-proof members 46 and 56 of the first and the third supporting arms are pulled/compressed and deformed by force in the vertical direction and sheared and deformed by force in the longitudinal direction. The vibration-proof member 51 of the second supporting arm 50 is sheared and deformed by force in the longitudinal direction and pulled/compressed and deformed by force in the right and left directions.
