PROBLEM TO BE SOLVED: To provide a power working machine capable of efficiently controlling torsional vibration. SOLUTION: The working machine includes: a clutch box 24 connected to a driving shaft 12 through a torsional coil spring 15; a clutch drum 16 connected to a transmission shaft 1 as a driven shaft; and a centrifugal clutch 10 having a clutch shoe 30 provided to be movable from the clutch box 24 toward the clutch drum 16. The clutch box 24 and the driving shaft 12 can be locked to each other so as to be integrally rotatable through the clutch shoe 30. By pressing the clutch shoe 30 onto the clutch drum 15, the clutch box 24 receives power from the driving shaft 12 through the torsional coil spring 15 in a connecting state of the centrifugal clutch 10. The driving shaft 12 and the clutch box 24 are locked to each other in an integrally rotatable manner in a disconnected state of the centrifugal clutch 10. COPYRIGHT: (C)2011,JPO&INPIT
