CABLE GAS CYLINDER

摘要

The present invention relates to a gas cylinder having a cable, wherein the cable is prevented from being twisted even when a chair rotates, to thereby improve operating reliability and product durability, wherein the gas cylinder comprises: a spindle which reciprocates in the upward and downward directions in accordance with the height adjustment of the chair; a cylinder which is arranged in the spindle, and the interior of which is filled with gas; a piston member which divides the interior of the cylinder into upper and lower sections; a pipe holder which seals the top of the cylinder; a gas release/cutoff pin arranged in the pipe holder to control the ingress/egress of the gas which fills the interior of the cylinder; a release arm arranged so as to contact one end of the gas release/cutoff pin to control the release/cutoff operation of the gas release/cutoff pin; a taper holder in which the release arm is arranged, and which is arranged in the spindle; and a rotation guide member interposed between the taper holder and the spindle so as to guide the rotation of the taper holder such that the taper holder is rotatable with respect to the spindle.
