Abstract: A strap is connectable to a battery pack without any specific portion for connection to the strap. A battery holder connects a strap to a battery pack detachably attachable to a tool body of a power tool. The battery holder includes a belt member that is detachably wound around an overall circumference of the battery pack, and a strap coupler to which the strap is detachably connectable.

Abstract: A lever device is configured such that, when first and second plates are relatively moved in a direction in which a second end part of the first plate and a fourth end part of the second plate are close to each other from a state in which the second end part and the fourth end part are separated from each other in an axial direction of a bolt, the first plate is rotated around a fulcrum positioned between a first engagement part and the second end part in the crossing direction so that the first plate is moved from an engaged position where the first engagement part and a non-circular part of the bolt or a nut are engaged to a non-engaged position where they are not engaged, and thereby removing a restriction of the relative rotation of the first plate to the non-circular part.

Abstract: Twisting of a locking member due to cogging torque is reduced without lowering the locking and unlocking operability for a user. A power tool includes a housing, an electric motor located inside the housing and including a permanent magnet, a shaft rotatable about an axis relative to the housing to transmit power from the electric motor, a locking member movable between a lock position and an unlock position in a nonenergized state of the electric motor and engageable with the shaft at the lock position to lock rotation of the shaft, and an abutting member that applies, to the locking member at the lock position, a force in a direction opposite to an axial torque caused by the permanent magnet and applied to the locking member.
