安全装置。A brake band is wrapped around the outer periphery of a drum that is fixed integrally with the sprocket that drives the saw chain.One end is attached to the frame, and the other end is configured so that it is pulled by a brake spring. The installed brake lever presses the brake spring so that the brake band is loose, and when the guide bar jumps due to kickback, the hand guard hits the hand holding the front handle and tilts forward. The brake lever releases the brake spring, pulls the brake band, and stops the rotation of the sprocket, and the switch lever, which is normally pressed by the hand guard to keep the switch in the ON state, A safety device for an electric chainsaw, characterized in that a device is provided that turns off the switch by being pushed out by the reaction force of a switch spring when the guard is tilted forward.
