Gas generator

摘要

The present invention provides a small gas generator which is capable of preventing a cup-like member or fragments thereof from being scattered, even when gas is discharged in the radial direction of the gas generator. The gas generator comprises a cup-like member having a cylindrical form with a bottom, which is integrated with an igniter assembly at a joining portion. The thickness of the joining portion is greater than the thickness of a side wall portion of the cup-like member.
