PURPOSE:To simplify a structure by facilitating the combustion of a gas generating agent based on the ignition of an ignitor, shortening ignition time before the gas generating agent is ignited, and dispensing with an ignition agent barrier, a rapid combustion line, and an explosion primer. CONSTITUTION:A housing 2 is formed into a cylindrical shape, and has a gas flow hole 4 in it. A storage tubular body 7 which stores an ignition agent 6 as an igniting means is mounted at a coaxial position to the housing 2 in the housing 2. A pellet type gas generating agent 12 is charged and disposed in a combustion chamber 11 at the outer periphery of the storage tubular body 7. A cooling collection material 13 is disposed at the peripheral wall of the combustion chamber 11. The storage tubular body 7 is achieved by forming the material mixture of nitrocellulose, pulp, an organic binder and the like into a cylindrical shape and has combustion property. The storage tubular body 7 is burnt by the ignition of the ignition agent 6, flame is transmitted to the combustion chamber 11 to burn the gas generating agent 12. |
