ング力調節機構。[Claims for Utility Model Registration] (1) Adjusting the elastic repulsive force of the spring by locking one end of the spring housed in the support base that supports the seat and changing the locking position. A spring force adjustment mechanism for a chair according to the present invention, wherein the grip has a shaft portion rotatably but immovably penetrated in an axial direction through an outer wall of a support base;
A feed screw provided integrally at the penetrating end of the shaft portion, a retainer that is screwed onto the feed screw to prevent one end of the spring from moving toward the outer wall, and an axis aligned with the tip of the feed screw. 1. A spring force adjustment mechanism for a chair, characterized in that the spring force adjustment mechanism for a chair is provided with a tip shaft for preventing slipping out and having an outer diameter substantially the same as the root diameter of the feed screw. (2) A claim characterized in that a locking ring is removably attached to the inner end of the shaft of the grip, and a thrust bearing is interposed between the locking ring and the inner surface of the outer wall. Spring force adjustment mechanism in the chair according to 1.
