Abstract
An electric power tool includes a tool body and a battery pack removably mounted to the tool body. The battery pack is used as a power source of the tool body. The electric power tool further includes a lock unit for keeping the battery pack mounted to the tool body and an interrupter switch for interrupting the operation of the tool body when the lock unit does not keep the battery pack mounted to the tool body. Accordingly, the electric power tool is not operable when the battery pack is not completely mounted to the tool body.
