Abstract
A gas generator includes a housing, an ignition device, a combustion chamber filled with a gas generating agent, a gas discharge port configured to discharge combustion gas to an outside, and a filter portion disposed between the combustion chamber and the gas discharge port, formed of a metal material, and configured to filter the combustion gas. The filter portion includes a first filter disposed on a side of the combustion chamber and a second filter disposed on a side of the gas discharge port and facing the first filter. The gas generator is provided with a space that is provided between the first filter and the second filter, so as to include a position where the combustion gas flows and to have a predetermined thickness in a direction of flow of the combustion gas, causing a flow rate of the combustion gas flowing into the second filter to decrease due to absence of the metal material.
