Abstract
A gas generator for an airbag is provided which is small and lightweight and enables an efficient use of the filter. This gas generator includes: a first member with one end open; a second member closing the open end of the first member; an ignition unit and a gas generating unit, both installed in a container formed by the first and second members; a filter arranged along an outer circumference of the container to enclose gas passing ports formed in the container; and a strip plate member arranged along an outer circumference of the filter, having a width smaller than the width of the filter and adapted to prevent a radial expansion of the filter, or a mesh member covering the filter.
