Abstract

An exhaust gas purifier of the type wherein a catalytic body is elastically supported within a metal casing. This is achieved by at least partly filling a space between the catalytic body and the metal casing with a dampening member comprising one or more wire blocks. The wire is preformed of a screw shape and that preformed wire is wound into the shape of the block. This block is stretched to elastically fit over the body, and the block is compressed between the body and the casing.
