PURPOSE: A failure of safety device of portable gas range is reduced, and the structure is simplified to improve safety and working process. CONSTITUTION: A gas pressure adjusting chamber is formed in upper part of a casing(1) by a diaphragm. A gas inlet(4) and a gas outlet are communicated. A parallel hole is formed to communicate the gas inlet with the gas pressure adjusting chamber. The parallel hole is sealed by mounting a rubber plate(27) closely. A protrusion is formed around a periphery of a valve shaft(8).
