いう極めて有用な新規的効果を奏するものである。In short, the present invention provides an operating lever for raising and lowering a working machine and an operating lever for traveling, which are arranged side by side on the same side of the driver's seat in the body traveling direction, and both levers can be tilted in the same direction. The height of the lever guide portion of the operating lever for raising and lowering the working machine is set to be higher than the height of the lever guide portion of the operating lever for traveling. Since the operation lower limit positions are arranged so as to be substantially the same, even if the operation lever for raising / lowering the work implement and the operation lever for traveling are arranged close to the same side of the driver's seat, the operator can operate each lever. When the vehicle is operated alternately, no trouble occurs such that the hand touches the adjacent operation lever or lever guide, and erroneous operation during traveling of the traveling vehicle can be prevented, thereby improving operability. Figure It is possible. By making the upper and lower positions of each operation lever substantially the same, the operator can operate each lever with almost no change in hand movement and operation feeling while being operated for different purposes. Performance can be improved. Etc., which are very useful and novel effects.
