ABSTRACT:
The filter for an inflator of the present invention includes a cylindrical compressed mesh unit, which is multi-folded in its substantially entire length, and the multi-folded mesh unit is provided by folding a cylindrical wire mesh knitted from a single metal wire by a predetermined length from its one or both end portions in the longitudinal direction, so as to be overlaid on the outer peripheral surface of the cylindrical wire mesh, and such a folded overlaying is repeated a plurality of times. Then, the cylindrical mesh unit thus constituted is compressed in its longitudinal direction. The above-mentioned compressed cylindrical mesh unit should have a cavity ratio of 70 to 80% in terms of cavity ratio C defined by the equation indicated below:
