圧装置の操作レバー装置。[Scope of Claim for Utility Model Registration] An engine whose engine speed can be controlled by an accelerator control mechanism, and a hydraulic control valve that controls the supply and discharge of pressurized oil discharged from a hydraulic pump driven by the engine to an actuator for driving a working machine. An operating lever device for a hydraulic system comprising: an operating lever that is swingably supported on a rotating shaft and switches and controls the hydraulic control valve by manual operation of an operating knob; The central portion of the lever is pivotably supported on a rotating shaft that is erected at a predetermined distance from the rotating shaft of the lever, and the accelerator control mechanism is operated in a direction to increase the engine speed by the swinging. A swing link, which is erected at a proper position of the operating lever, and when the operating lever is rotated in one direction, engages with one end of the swing link and rotates the swing link in a direction that increases the engine speed. A first engagement piece and the operating lever are erected at appropriate positions, and when the operating lever rotates in the other direction, it engages with the other end of the swinging link and moves the swinging link in a direction in which the engine speed increases. An operating lever device for a hydraulic device, characterized in that it is comprised of a second engaging piece that is rotated to rotate the operating lever device.
