The present invention provides an inflator including pressurized gas, in which a discharge amount of combustion residues is suppressed. High temperature combustion residues in combustion gas of a gas generating agent 36 remain in an inflator 10 and its discharging to the outside is suppressed due to the composition of the gas generating agent 36, a temperature difference between combustion gas and pressurized gas isolated from each other by a first rupturable plate 40, collision of the combustion gas to a wall surface 22a and the like. Further, a compact inflator is also provided. That is, the present invention provides an inflator inflating an air bag with pressurized gas and combustion gas generated by combustion of the gas generating agent, in which the following requirements are satisfied: (1) pressurized gas contains an inert gas but it does not substantially contain oxygen; (2) in the gas generating agent, a pressure is 0.8 or less; (3) a mole ratio of an amount of pressurized gas and an amount of combustion gas generated of a gas generating agent is 1 to 10; (4) a ratio of a mass of pressurized gas and a mass of a gas generating agent is 1 to 10; (5) a mass of a gas generating agent is 1 to 30 g; and (6) a charging pressure of pressurized gas is 30,000 to 67,000 kPa.
An inflator inflating an air bag with combustion gas generated by combustion of a gas generating agent and a pressurized medium, and comprising a means for making the combustion gas strike against one or at least two wall surfaces to have combustion residues in the combustion gas adhered to the one or at least two wall surfaces and a means for making the combustion gas contact with the pressurized medium to cool and solidify the combustion residues contained in the combustion gas due to a temperature difference, wherein a melting point of the combustion residues produced by combustion of the gas generating agent is not less than a discharging temperature of gas generated from the gas generating agent.
