HYBRID INFLATOR

In a hybrid inflator, a housing houses a gas generator to generate a combustion gas in a housing recessed portion on a bottom portion side. A lid body provided at an outflow port of the housing and a lid body provided at a sealed portion side of a pressurized gas in a bottle in a gas discharge port portion separate the sealed portion of the pressurized gas in the bottle from outside. When the hybrid inflator is activated, the two lid bodies are broken by generation of the combustion gas from the gas generator, and whereby the pressurized gas is discharged from a discharge port of the gas discharge port portion. The gas generator is detachably assembled to the housing with respect to the housing recessed portion of the housing.
