This working machine is provided with: an output shaft to which a front end tool can be mounted; a housing for rotatably supporting the output shaft; and a protective cover mounted to the housing so as to cover the outer periphery of the front end tool mounted to the output shaft. The protective cover is configured to be displaceable between a working position at which a part of the outer periphery of the front end tool is exposed to enable a material to be worked to be cut, and a protection position at which the protective cover covers a greater area of the outer periphery of the front end tool than when the protective cover is at the working position. The protective cover is pressed by a pressing member so as to be displaced from the working position to the protection position.
