Abstract
In an electric working machine, a scroll portion is provided at one of left and right sides of a machine body, and a relay member functioning as a power switch in which a power on/off key is removably inserted is provided at the other side of the machine body. The relay member is provided between a motor-driving battery and a control section so that the battery and control section can be electrically connected with each other by insertion, in the relay member, of the power on/off key and disconnected from each other by removal, from the relay member, of the power on/off key.
