PROBLEM TO BE SOLVED: To provide a walking type work machine easy to adjust a steering brake even if a steering lever and the steering brake are linked by an electric linkage mechanism and a control form of a control section is simplified.SOLUTION: A walking type work machine includes: an actuator 49 which operates a steering brake 38L; and a control section 72 which controls the actuator 49 on the basis of detection information on an operation position detection sensor 65 for detecting an operation position of a steering lever 61L so as to operate the steering brake 38L to a braking state provided with braking force having a strength corresponding to a detection operation position of the operation position detection sensor 65L. An interlock mechanism 66 of the steering lever 61L and the operation position detection sensor 65L increases operation change amount of the operation position detection sensor 65L interlocking with oscillation of a reference stroke of the steering lever 61L as the operation position of the steering lever 61L comes close to a stroke end on a grip side.SELECTED DRAWING: Figure 14

    【課題】操向レバーと操向ブレーキとを電気式の連係機構によって連係させても、かつ制御部の制御形態を簡素化しても、操向ブレーキを調節し易い歩行型作業機を提供する。【解決手段】操向ブレーキ38Lを操作するアクチュエータ49、操向レバー61Lの操作位置を検出する操作位置検出センサ65Lの検出情報を基にアクチュエータ49を制御して、操作位置検出センサ65Lの検出操作位置に対応した強さの制動力を備える制動状態に操向ブレーキ38Lを操作する制御部72を備えている。操向レバー61Lと操作位置検出センサ65Lとの連動機構66は、操向レバー61Lの基準ストロークの揺動に連動した操作位置検出センサ65Lの作動変化量を、操向レバー61Lの操作位置が握り側のストロークエンドに近づくほど大にする。【選択図】図14
