作装置。 A support part for the pivot point of the operating lever is provided near the control valve push rod in the gas spring for raising and lowering the seat plate of the chair or tilting the backrest, etc., so that the operating lever can be moved as appropriate. A pressing portion facing the tip of the push rod is formed at the portion so as to be movable along a plane perpendicular to the axis of the push rod in the protruding and retracting direction in accordance with rotation of the operating lever, and the surface of the pressing portion is , a cam groove is formed into which the tip of the push rod fits and contacts the bottom surface, and as the operating lever is rotated in one direction, the push rod is retracted through the bottom surface of the cam groove, and the operating lever is rotated in the other direction. 1. A gas spring control and operating device, characterized in that the push rod is formed on an inclined cam surface that allows the push rod to protrude as the push rod is operated, and the cam groove is provided with a locking portion that holds the push rod in a largely retracted position.
