Abstract: A dust cover has improved operability for attachment and detachment. A power tool to which a disk tool is attachable includes an electric motor including a motor shaft, a housing accommodating the electric motor and having an inlet to draw outside air, a dust cover being a plate including a filter covering the inlet and being attachable to and detachable from the housing, a grip extending from the housing in a direction perpendicular to the motor shaft and located between the disk tool and the inlet in a direction in which the motor shaft extends, and a spindle coaxial with the motor shaft, protruding from an end of the housing to receive the disk tool, and rotatable by the electric motor.

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.

Abstract: A grinder includes a motor, a housing, a spindle and a cover. The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The cover at least partially covers a tool accessory mounted on the spindle. The cover includes a first cover part and a second cover part. The first cover part is fixed to the housing and at least partially covers the tool accessory from above. The second cover part is held such that it is capable of moving relative to the first cover part. The grinder is configured such that the area of the tool accessory covered by the cover changes in accordance with the relative movement.
