Abstract: An impact tool includes a motor, a spindle configured to rotate by a rotational force of the motor, a tool holding shaft at least a part of which is disposed in front of the spindle, a movable anvil movably supported by the tool holding shaft; and a hammer supported by the spindle and striking the movable anvil in a rotation direction without being displaced in an axial direction.

Abstract: Breakage of a controller in an electric work machine and components around the controller is reduced. The electric work machine includes a motor, a trigger switch operated to activate the motor, a controller that controls the motor, a housing including a grip on which the trigger switch is located and a controller compartment accommodating the controller, and a deformation reducing member located at an interface between the grip and the controller compartment to reduce deformation of the housing.

Abstract: A power tool, such as an impact driver, includes a motor having a rotor that rotates relative to a stator, and a centrifugal fan that rotates together with the rotor. A motor housing and a rear housing house the motor. Overlapping parts of the motor housing and the rear housing radially surround an outer circumference of the centrifugal fan. Air exhaust ports are defined in each of the overlapping parts and are offset in an axial direction of the rotor. Fluid communication paths are defined between the air exhaust ports in the overlapping parts. The fluid communication paths have an opening area or width in the axial direction that is smaller than an opening area or width in the axial direction of the air exhaust ports.

Abstract: An impact tool includes a motor, a first hammer, an anvil, and a second hammer. The first hammer is configured to be rotated by driving of the motor. The anvil is configured to be hammered in a rotation direction by the first hammer. The second hammer is configured to be switchable between a state being linked and a state not being linked to the first hammer. The impact tool ensures selections of a first hammering mode in which only the first hammer hammers the anvil and a second hammering mode in which the first hammer and the second hammer hammer the anvil.
