Abstract: A tool includes a first accessory, at least two first attachment portions for detachably and selectively attaching the first accessory, and a single first intermediate member provided in common for the at least two first attachment portions. The first intermediate member includes at least one pressed portion configured to, when the first accessory is attached to one first attachment portion arbitrarily selected from the at least two first attachment portions, be directly or indirectly pressed by the first accessory. The first intermediate member is configured to be displaced when the at least one pressed portion is pressed. The tool further includes a single first sensor configured to detect that the first intermediate member is displaced.

Abstract: An electric tool includes a motor, a first intermediate member configured to be displaced when a first accessory is attached to a first attachment portion, a second intermediate member configured to be displaced when a second accessory is attached to a second attachment portion, and a first interlock member. The first interlock member mechanically moves in conjunction with the respective displacements of the first intermediate member and the second intermediate member. The first interlock member is displaced in the same direction between when the first accessory is attached and when the second accessory is attached, and is cumulatively displaced when the first accessory and the second accessory are attached. The electric tool is configured in such a manner that power supply to the motor is permitted only in a state that the first interlock member is cumulatively displaced.

Abstract: A wheel cover including a first cover attachable to a body of a power tool and a second cover removably attachable to the first cover reduces rattling of the second cover. The wheel cover includes 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 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 opposite to the body of the power tool, and a rattle restrainer that reduces, while the second cover is attached to the first cover, rattling of the second cover relative to the first cover.

Abstract: A power tool, such as a grinder, may include: a prime mover such as a motor; a power-transmission mechanism operably connected to the prime mover; a housing that houses the prime mover and the power-transmission mechanism; and a tool-accessory retaining part for holding a tool accessary. The tool-accessory retaining part is operably connected to the power-transmission mechanism. An accessory is mounted on the housing in a detachable manner. A link member moves in response to mounting and demounting of the accessory. A detection sensor is housed in an interior of the housing and includes a non-contact sensor device. The detection sensor is configured to detect movement of the link member using the non-contact sensor device.

Abstract: A hand-held tool, such as a disc grinder, is used to perform work at a high work site, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool, such as a tether strap. If a coupling part that couples the suspension tool to the hand-held tool is damaged, this fact is notified to a user. Thereby, an original function of the suspension tool can be reliably performed. If a large impact is applied to a coupling member via a suspension tool, the coupling member is displaced to a second position, due to the deformation of a first position retaining member. A conductive portion disengages from contacts to cause a power circuit to be shut off, thereby prohibiting a main body part from being activated.
