PROBLEM TO BE SOLVED: To provide an ambulatory electric working machine having a lock and release member of an operation lever with a good operability.SOLUTION: The ambulatory electric working machine includes: an operation lever 40 supported to freely swing up and down around the first horizontal axis center 41 of the operation handle 6 a position sensor which detects the operation lever 40 to be positioned at the gripping position c and a regulation means which allows an electric motor to drive the working machine if the operation lever 40 is detected by the position sensor to be positioned at the gripping position c. The working machine also includes a restraint member 50, which inhibits the operation lever 40 from being operated at the gripping position c, is provided to freely swing up and down around the second horizontal axis center 51, near the carrying part 6C of the operation handle 6 or at the operation lever 40, in the range from the position at which the operation lever 40 is inhibited to be operated to the gripping position c, to the position at which the operation lever is allowed to be operated to the gripping position c.COPYRIGHT: (C)2013,JPO&INPIT【課題】操作性のよい操作レバーのロック及び解除部材を備えた歩行型電動作業機を提供する。【解決手段】操作レバー40を操縦ハンドル6の第1横軸芯41周りに上下揺動自在に支持し、操作レバー40が把持位置cに位置することを検出する位置センサを備え、位置センサにより操作レバー40が把持位置cに位置することが検出されると電動モータの駆動を許容する制御手段を備え、操作レバー40の把持位置cへの操作を阻止可能な牽制部材50を、操作レバー40の把持位置cへの操作を阻止する位置及び操作レバーの把持位置cへの操作を許容する位置に亘って、第2横軸芯51周りに操縦ハンドル6の持ち手部6Cの近傍または操作レバー40に上下揺動自在に備えてある。【選択図】図3
