A gas generator comprising:
- a cylindrical housing having an initiator shell provided with a plurality of igniter devices and a closure shell;
- a ring-shaped filter element provided in the housing along a circumference of an inner peripheral wall of the housing;
- a first combustion chamber formed within the ring-shaped filter element and loaded with gas generants;
- a cylindrical member configured to partition the combustion chamber into two combustion chambers;
- and
- a second combustion chamber formed in the cylindrical member and loaded with gas generants, wherein
- a first end side in a length direction of the cylindrical member contacts the initiator shell,
- an igniter device is provided at a portion where the initiator shell faces the second combustion chamber, and
- a disk-shaped filter element is provided at a second end side in the length direction of the cylindrical member.
