Abstract
To provide a gas generator for an air bag that is designed to have a sufficient and fix seal at the area where igniting means is installed, with which a housing having a reduced weight is possible, and which manufacture is easy.
In a gas generator for an air bag composed to include a housing which has gas discharge ports, igniting means which is activated by an impact, and gas generating means which is ignited by the igniting means and burns and generates a combustion gas, a gas generator for an air bag which is made by having the igniting means provided with a cylindrical collar member used for an attachment on its outer circumference, having the housing provided with an igniting means attaching member that has a cylindrical inner circumferential surface in which the cylindrical collar member fits, having the inner circumferential surface and/or outer circumferential surface of the cylindrical collar member provided with a groove in the circumferential direction, and having the seal member attached by pressing it inside the groove.
