The present invention relates to a gas pressure adjuster, wherein the gas pressure adjuster comprises a constant pressure device for converting high-pressure gas into low-pressure gas and a pilot for setting the target pressure of the constant pressure device. The pilot includes: a diaphragm accommodated in an inner space to be able to reciprocate; a control hole opened to allow the inner space to communicate with the outside and long extended in parallel with a reciprocating direction of the diaphragm; a controlling member having a movable part disposed in the control hole to be able to reciprocate along the control hole and an extension part long extended from one end of the movable part; a spring for elastically connecting the diaphragm and the movable part to each other; and a stopper member for closing the control hole and having a penetration hole through which the extension part passes. While the stopper member closes the control hole, one end of the extension part is exposed to the outside. The one end of the extension part exposed to the outside is rotated and thus the movable part reciprocates along the control hole. According to the present invention, even while the stopper member closes the control hole, the gas pressure can be controlled by rotating the one end of the extension part exposed to the outside. |
