Abstract
A working machine includes: an output shaft to which a tip tool is attachable; a housing rotatably supporting the output shaft; and a protection cover attached to the housing so as to cover an outer periphery of the tip tool which is attached to the output shaft. The protection cover is configured to be displaceable between a processing position to expose a part of the outer periphery of the tip tool to thereby allow cutting of a workpiece, and a protecting position to cover the outer periphery of the tip tool more than in the processing position, and is biased by a biasing member to be displaced from the processing position to the protecting position.
