Abstract
An electric power tool can include a main body, which rotates a motor with a pull operation of the switch lever and actuates a head tool by a rotative force of the motor, and an auxiliary tool configured for attaching and detaching to and from the electric power tool main body. In the main body, an actuating part actuated with the pull operation of the switch lever is provided. The auxiliary tool includes a detecting part, which noncontactly detects an actuation of the actuating part, and an electric circuit section for actuating electric devices, provided in the auxiliary part, by a detecting actuation of the detecting part.
