The inflator satisfies both of the strength of a first impact of the airbag and a keeping operation for a duration of expansion of the airbag. The inflator 100 supplies gas into an airbag mounted on a motor vehicle and deploys the same. A first chamber 1e where a gas-blowing outlet 1f is provided and a gas-generating agent 7 generating the gas while being ignited by means of an initiator 5 is encapsulated. A filter 8 is arranged between the gas-blowing outlet 1f of the first chamber 1e and the gas-generating agent 7, absorbs heat of combustion of the gas-generating agent 7, and captures a residue thereof. A second chamber 1d is partitioned from the first chamber 1 e with a flow amount control member 2 where the compressed gas 6 is encapsulated. A blocking member 2b of a control hole 2a of the flow amount control member 2 is provided which opens the control hole 2a by being ruptured or removed by expanding pressure of the gas-generating agent 7 (Fig. 1). |
