Abstract
An electric power work device simplifies a mechanism of a battery attachment part and easily removes a battery from the battery attachment part. A chain saw includes a body case, a cutting part (a work tool), and the battery. A battery removal mechanism for removing the battery is provided on a rear part of the body case. The battery removal mechanism includes a lower end of the battery and a bottom surface of the body case. The lower end of the battery protrudes downward from the bottom surface of the body case, and a frontmost end of a lower part of the battery is disposed in front of a rear end of a lower part of a top handle. Another battery removal mechanism includes a protrusion on the bottom surface of the body case and in front of the lower end of the battery.
