a first cover attachable to a body of the power tool to cover at least a portion of a first surface of the tip tool, the first surface being adjacent to the body of the power tool;
a second cover removably attachable to the first cover to cover at least a portion of a second surface of the tip tool, the second surface being opposite to the body of the power tool; and
a rattle restrainer configured to reduce, while the second cover is attached to the first cover, rattling of the second cover relative to the first cover,
wherein:
the rattle restrainer is configured to reduce rattling of the second cover at least in a radial direction of the tip tool intersecting with the output shaft or in an axial direction parallel to the output shaft,
the first cover includes:
a first plate face protector facing the first surface of the tip tool to protect a first plate face of the tip tool, and
a first periphery protector facing a peripheral edge of the tip tool about the output shaft to protect a periphery of the tip tool,
the second cover includes:
a second plate face protector facing the second surface of the tip tool to protect a second plate face of the tip tool, and
a second periphery protector facing the peripheral edge of the tip tool about the output shaft to protect the periphery of the tip tool,
the second cover is attachable to the first cover to have the second periphery protector overlapping the first periphery protector, and
the rattle restrainer includes at least one first elastic strip to urge the first periphery protector and the second periphery protector away from each other.
