Claims

[Scope of utility model registration request]

In a chair incorporating a gas spring that adjusts at least one of the inclination angle of the seat and back and the height of the seat, the switch section of the gas spring is pressed and released at one end to control the gas spring. At the intermediate position of the main shaft of the operating lever that switches between the free state and the locked state,
A pair of short shaft support protrusions facing each other via a groove are formed on a mounting plate fixed to the lower surface of the seat, in which a short shaft extends to both sides in a direction perpendicular to the main axis direction, and a pair of short shaft support protrusions on both sides thereof. A pair of openings are formed in the mounting plate, and both sides of the abbreviated plate □ spring elastically pinch the projecting piece portion through the opening from the back side of the mounting plate, and a downwardly protruding shape is formed. 1. The operating lever is fitted into the insertion holes formed in the tip protrusions of both side pieces by utilizing the short shaft portion or spring elasticity of the operating lever, so that the operating lever is tilted to the mounting plate using the short shaft portion as a fulcrum. A pivoting device for an operating lever for adjusting the posture of a chair, characterized in that the operating lever is pivotably mounted.
