Abstract: A power tool includes a motor configured to provide driving force to a tool accessory, a braking mechanism disposed on a driving-force-transmission path from the motor to the tool accessory and configured to put a brake on driving of the tool accessory, at least one attachment portion configured such that an accessory is removably attachable thereto, and a restricting member configured to be directly or indirectly pressed and displaced by the accessory when the accessory is attached to any one of the at least one attachment portion. In a state in which the accessory is not attached to any of the at least one attachment portion, the restricting member is located at a preventive position at which between-members abutment prohibits releasing of a braked state effected by the braking mechanism.
