Abstract:
The present invention is a gas generator which has an enhancer chamber that includes an igniter on a first end side of a cylindrical housing. The enhancer chamber is an internal space interposed, in the axial direction, between the igniter which is fixed to the first end side, and a cup-shaped partition disposed inside the cylindrical housing, and the enhancer chamber contains an enhancer agent. The cup-shaped partition has a bottom part, a peripheral wall part, and an opening. The peripheral wall part has a peripheral wall body part and an annular part that extends outward from the peripheral wall body part. The peripheral wall body part has a plurality of nozzles that penetrate the peripheral wall body part in the thickness direction. The outer surface of the annular part of the cup-shaped partition is in contact with the inner wall surface of the cylindrical housing. A cylindrical gap is formed between the peripheral wall body part and the inner wall surface of the cylindrical housing that faces the radial direction. The nozzles formed in the peripheral wall body part are disposed so as to face the cylindrical gap, and a gas generating agent is not present in the cylindrical gap.
