    摘要： 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.

    摘要： A power tool allows easy handling. The power tool includes a brushless motor including a stator and a rotor rotatable relative to the stator, a motor housing that is cylindrical and accommodates the brushless motor, a gear housing in front of the motor housing, a grip housing behind the motor housing and extending in a front-rear direction, and being cylindrical and having a smaller diameter than the motor housing, a controller housing behind the grip housing and accommodating a controller including a switching element, and a power cord connected to the controller housing.

    摘要： A grinder (100) includes a motor (12), a housing (4, 6, 30), a spindle (24), a first cover (120), and a second cover (170). The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The first cover is provided in the circumferential direction of the spindle, is fixed to the housing, and at least partially covers a tool accessory (40), which is mounted on the spindle, from above. The second cover is detachably mounted on the housing (6) independently of the first cover.

    摘要： An electric power tool disclosed herein may include a motor; a power transmission mechanism connected to the motor; a housing that houses the motor and the power transmission mechanism; a tip tool holder connected to the power transmission mechanism; a cover covering the tip tool holder partially; a first locking mechanism configured to switch between a first locking state and a first unlocked state; and a second locking mechanism configured to switch between a second locking state and a second unlocked state. In the electric power tool, the cover may become detachable from the housing when the user performs the second unlocking operation on the second locking mechanism and the first unlocking operation on the first locking mechanism.
