<p>PROBLEM TO BE SOLVED: To provide a control lever device capable of outputting a hydraulic signal by controlling the control lever in the rotational direction, simplifying the structure, facilitating the assembly and adjustment, reducing control force, imposing no restriction on a layout and being finely returned to the original neutral position when taking the hand off after the control lever is rotationally controlled. SOLUTION: When the control lever 8 is rotated around a lever shaft 8a, a shaft 13 supported by bearings 14 and 15 is rotated. The rotation of the shaft 13 converts a piston 5 into the movement in the direction to be displaced by first and second levers 18 and 19, and a piston 6 is displaced. When the piston 5 is displaced, the hydraulic signal is outputted from a discharge port 25. A disc plate 9 is divided into a first disc plate 9a mounting the root of the control lever 8 thereto and a second disc plate 9b supported by a tilting fulcrum 11 in a tiltable manner. The first disc plate 9a is separated from the second disc plate 9b to rotate around the lever shaft 8a of the control lever 8.</p> |
