PROBLEM TO BE SOLVED: To provide a walking type electric working machine hardly affected by an object intruding into the inner side of a control lever during the operation of holding the control lever.SOLUTION: The control lever 40 is swingably supported around a horizontal shaft center 41 of a steering handle 6. The control lever 40 includes a portion 42 whose top is open and whose cross section is box-shaped. Bottom surfaces 42a and 42a of the box-shaped portion 42 are inclined downward from either side to the center in the lateral direction. A position sensor 44 for detecting that the control lever 40 is located at a holding position is disposed at a position separated upward from the bottom surfaces 42a and 42a of the box-shaped portion 42 and closer to a right or left vertical wall 42b of the bottom surface 42a and 42a of the box-shaped portion 42. The working machine also includes a control means for permitting the driving of an electric motor when the position sensor 44 detects that the control lever 40 is located at the holding position as the position sensor 44 is brought into contact with the bottom surface 42a of the control lever 40.COPYRIGHT: (C)2013,JPO&INPIT【課題】操作レバーの把持操作において操作レバーの内面側に入り込む侵入物の影響を極力受け難い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の横軸芯41周りに揺動自在に支持し、操作レバー40は上面が開口する断面が箱形形状42の部分を備え、箱形形状の部分42の底面42a,42aは左右両側から左右中央側にかけて下方に傾斜する形状であって、箱形形状の部分42の底面42a,42aから上方に離間した位置に操作レバー40が把持位置に位置することを検出する位置センサ44を、箱形形状の部分42の底面42a,42aにおける左右いずれかの縦壁42b寄りに配置し、位置センサ44が操作レバー40の底面42aに接触することにより操作レバー40が把持位置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てある。【選択図】図5
