Abstract
A gas generator for an airbag allows maintaining combustibility as originally designed. An ignition energy generated by an activation of a first igniterflows via a first communication hole, a first intermediate chamberand second communication holes, into a second combustion chamber, to cause a gas generating agentto ignite and burn. The ignition energy flows into the second combustion chamberwith making a detour, and therefore, the gas generating agent prevents from broken by the impact and the combustibility thereof is never changed.
