Claims

[Scope of utility model registration request]

The main body disposed in the gas passage is provided with a valve hole that communicates with the gas passage, and the main body is provided with a valve element that can open and close the valve hole on the upstream side, and the valve element receives the biasing force of the spring. A gas release preventer characterized in that the valve element is biased in the opening direction by a spring, and when the gas flowing through the gas passage reaches a predetermined flow rate or more, the valve element is closed against the biasing force of a spring.
