Abstract
A gas generator for an air bag has a coolant/filter that includes at least two circular cylindrical filter units juxtaposed in the axial direction of the gas generator. Each filter unit is made by compression molding a metallic wire mesh, prepared by knitting a metallic wire, into a circular cylindrical configuration. By using at least two circular cylindrical filter units, the weight and density of the coolant/filter, along the entire length thereof, can be made even to enhance even cooling and purification.
