Disclosed is a gas generator that can reliably prevent gas leakage during operation and crushing of a gas generating agent during non-operation, and can be manufactured more inexpensively and easily. A gas generator 1A includes a housing including a top plate portion 21 and a bottom plate portion 11, a cylindrical filter 90, a gas generating agent 61 formed of a plurality of granular molded bodies, and a metal net material. And a pressing member 80A made of a molded product formed by processing. The pressing member 80A is positioned at a distance from the annular first contact portion 81 that contacts the inner peripheral surface of the filter 90 and the top plate portion 21, faces the gas generating agent 61, and contacts the plate-shaped first contact portion. 2 abutting portions 82. The gas generating agent 61 is elastically biased toward the bottom plate portion 11 by the second contact portion 82 when the pressing member 80A is elastically deformed by being sandwiched between the top plate portion 21 and the gas generating agent 61. Is retained. [Selection] Figure 1 |
