Abstract
In a work vehicle, a pivot axis of an operating lever and a rotary axis of a potentiometer are located on a same axis. An interlocking mechanism includes an input part which inputs power of the operating lever following the operating lever about the pivot axis as a pivot, and an output part which is supported to a rotary operation shaft and outputs power of the input part to the rotary operation shaft. The input part and the output part are operably connected via a connecting pin.
Claims7
A work vehicle comprising:
- a traveling device;
- a driving device which drives the traveling device;
- an operating lever which performs speed change operation of the driving device;
- a potentiometer which detects an operation position of the operating lever;
- a controlling means which operates speed change of the driving device based on a detection result of the potentiometer;
- and
- an interlocking mechanism which interlocks the operating lever with a rotary operation shaft of the potentiometer;
- wherein a pivot axis of the operating lever and a rotary axis of the rotary operation shaft are located on a same axis, and
- wherein the interlocking mechanism includes:
- an input part which pivots following the operating lever about the pivot axis of the operating lever as a pivot, and inputs power of the operating lever, the input part comprising a first through hole,
- an output part which is supported to the rotary operation shaft of the potentiometer and outputs power of the input part to the rotary operation shaft, the output part comprising a second through hole, and
- a connecting pin extending between the first through hole and the second through hole, thereby operably connecting the input part and the output part with each other.
