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,
wherein:
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 an operation of releasing a braked state effected by the braking mechanism,
in a state in which the accessory is attached to any one of the at least one attachment portion, the restricting member is located at an allowable position at which the between-members abutment does not take place so that the operation of releasing the braked state is allowed,
the at least one attachment portion includes a plurality of attachment portions, and
the restricting member is a single member provided to serve for the plurality of attachment portions.
