Abstract

The present invention relates to a gas range valve, wherein, in a state in which a shaft unit is pressed downwards, a shaft is rotated towards the rod of an opening and closing valve around a rotation guide, such that the rotation guide may be rotated so that a gas flow path and a gas outlet may communicate with each other. A press-fitting unit, which is integrally formed at the shaft, is integrally rotated along with the shaft to pressurize the rod, such that the opening and closing valve may retreat by the rod, thereby opening the passage between a gas inlet and the gas flow path. According to the present invention, the press-fitting unit is integrally formed on the outer surface of the shaft such that the press-fitting unit may directly press-fit the rod by the rotation of the shaft, and the rod is directly press-fit into the press-fitting unit, thereby eliminating concerns regarding deterioration of the rotating press-fitting force of the shaft. The press-fitting unit is bent from the shaft towards the rod such that the radius of rotation from the press-fitting unit to the rod may be shortened. Because of the shortened radius of rotation, the time for the press-fitting unit to reach the rod when the shaft is rotated may be shortened, such that the rod may be quickly press-fit. In particular, the press-fitting unit is integrally rotated and applies pressure by means of the rotation of the shaft, thereby simplifying components. Because of the simplified components, the assembly process can be conveniently performed, and maintenance and repair can be conveniently performed, thereby increasing reliability of the product.
