機構。 A coil spring or an equivalent shock absorber is housed in a leg frame such as a leg or support to which the seat plate of the chair is attached, and a stopper member is applied to the tip of the shock absorber, and the spring is housed. The seat plate of the chair is pivoted to the upper end of the leg frame with the seat plate attached so that the seat plate can swing up and down in a substantially horizontal direction, and the front end side of the seat frame to which the seat plate is attached is pivoted. Alternatively, a protruding lever block for operating the above-mentioned shock absorber is provided below the pivot joint of the seat frame, integrally with the seat plate or the seat frame, and the tension rod of the above-mentioned shock absorber is attached to the lower end of the block. The distal end side of the rod is pivotally connected, and the rear end side of this tension rod is inserted into a frame housing the buffer body so that the rear end of the rod supports the rear end of the buffer body, and A shock absorber holder whose front and back position can be changed via a vertically movable wedge member is provided at the front end of the shock absorber in the leg frame, so that the degree of shock absorption of the shock absorber can be changed. A cushioning mechanism for the seat of a chair.
