PROBLEM TO BE SOLVED: To provide a gas discharging apparatus with which a gas can be efficiently discharged without engaging a worker in dangerous work when the gas leaks. SOLUTION: This gas discharging apparatus for gas supply equipment is constituted so that a gas supplying source 2 is housed in a casing 1 for preventing the leakage of the gas to the outside. An air intake cover 5 is usually in close contact with a wind receiving cup 8 by the elastic force of a spring 9. When the gas leaks and is started to be discharged urgently, the inside pressure of the casing 1 becomes negative, then, the cup 8 is sucked by the negative pressure, and an air intake is formed for sucking air to the inside of the casing 1. As a result, the amount of air to be sucked can be increased automatically in an emergency even without manual aid and the pressure necessary for discharging the gas urgently can be lowered.
