PROBLEM TO BE SOLVED: To provide an operating lever device enabling miniaturization of an entire device by attaining a small detent mechanism. SOLUTION: The operating lever device includes: control valves 10, 11 each having a piston 20 and a spool 30 which moves within a spool hole 30h inside a valve body 6 as it receives secondary hydraulic pressure at one end and receives the pressure of the piston 20 from the other end and which converts the primary hydraulic pressure inputted into the secondary hydraulic pressure according to the amount of movement of the piston 20 and outputs the secondary hydraulic pressure; a guide member 40 for guiding the movement of the piston 20; and an operating lever 3 which makes contact with the other end of the piston 20 to generate pressure and control the amount of movement of the piston 20. A detent mechanism comprising a stepped portion 44 and a pressing mechanism 45 is provided near the guide surfaces of the guide member 40 and the piston 20. COPYRIGHT: (C)2010,JPO&INPIT
