To make it possible to stop the continuation of a state where a vehicle is driven to reverse in a case where there is a possibility that clamping pressure is generated, regardless of the inclination of a vehicle body when a walking-type work vehicle reverses.SOLUTION: The downward rotation of a handle rod 3 is restricted at a prescribed position where the handle rod 3 becomes inclined upward toward a rear side regardless of the inclination of a vehicle body 6. Further, when positioned at the prescribed position, the handle rod 3 is rotated upward only in a case where a load of a fixed magnitude or more is applied. In addition, when the handle rod 3 is rotated upward from the prescribed position to a fixed extent or more, the operation of a power source is stopped. Regardless of the inclination of the vehicle body, when the load of the fixed magnitude or more is applied to the handle rod, the handle rod is rotated upward, and the supply of power to a drive part is stopped in response to the rotation.SELECTED DRAWING: Figure 6

    【課題】歩行型作業車両が後進するときの車体の傾きにかかわらず、挟圧が発生した可能性がある場合に車両が後進しようとする状態が継続するのを停止できるようにする。【解決手段】車体6の傾きにかかわらず、後方に向かうに従って上方に向かうように傾いた状態となる所定位置でハンドル杆3の下方向への回動が規制される構成とし、更に、所定位置に位置しているときは、一定以上の荷重が付加された場合にのみハンドル杆3が上方向へ回動する構成とした上で、ハンドル杆3が所定位置から上方向へ向かって一定以上回動したときに動力源の動作が停止されるようにし、車体の傾きにかかわらず、ハンドル杆に一定以上の荷重が加わたっときに、ハンドル杆が上方向に向かって回動し、回動に応じて駆動部に対する動力の供給が停止するようにしている。【選択図】図6
