Claims

[Claims for Utility Model Registration] 1. The operating lever 5 of the forward/reverse switching device 4 is arranged at a location near the grip 2a on the inner side of the aircraft body than the grip 2a of the control handle 2, and is moved vertically. A forward/reverse switching structure for a walk-behind work vehicle that is installed to switch between a forward position F and a reverse position R. 2. The operating lever 6 of the forward/reverse switching device 4 is placed at a location near the grip 2a of the control handle 2 on the inner side of the aircraft body, and can be moved between the forward position F and the reverse position R by vertical swinging. The lock is attached in a state where the control lever 6 is switched to the forward position F or the reverse position R on the ascending side and held in the reverse position R or the forward position F on the descending side. A walking-type work in which a tool 17 is provided and is biased to automatically lock as the operating lever 6 is lowered, and a release operating tool 7 of the locking tool 17 is disposed near the grip portion 2a. A structure for switching forward and backward movement of a car. 3. Hold the forward operating lever 8 and reverse operating lever 9 of the forward/reverse switching device 4 at the grip portion 2a of the operating handle 2.
It is disposed at a location closer to the grip portion 2a inside the fuselage and is attached to be able to swing up and down, and when the forward operating lever 8 is operated to the lowered forward position F, the reverse operating lever 9 is moved to the raised release position. O
The forward operating lever 8 is automatically switched to FF, and as the reverse operating lever 9 is operated to the lower reverse position R, the forward operating lever 8 is automatically switched to the upper release position OFF. Interlocking means 23, 2 for interlocking the reverse operation lever 9
A forward and backward switching structure for a walking work vehicle equipped with 4.
