<P>PROBLEM TO BE SOLVED: To quickly and accurately detect an inclined rotation angle which is the operation quantity of an operating lever of a construction machine, without carrying out integrating operation of output of sensors, while eliminating the influence of the vibration of a machine body. Ž<P>SOLUTION: This operating lever device 2 includes an operating lever 6, mounted to a lever support body 4 to be operated in a tiltably rotatable manner; a first acceleration sensor S1 mounted to the operating lever 6 to detect acceleration in a direction of a vertical plane V1, including the direction of tiltably rotatable operation; a second acceleration sensor S2, mounted to the lever support body 4 to detect acceleration, in a direction of a vertical plane V2 substantially in parallel with the vertical plane V1 of the first acceleration sensor S1; and a controller 10 for computing the inclined rotation angle and inclined rotation direction of the operating lever 6, based on the output of the first and second acceleration sensors S1, S2, and outputting an operation signal to an operated body 8.
