Abstract
In an exhaust converter, where a casing is made by fastening and welding a cylindrical metal plate wrapped on an outer periphery of a supporting mat that is wrapped on an outer peripheral surface of a catalyst carrier, recovering means is formed at either or both of the supporting mat and the casing for recovering positional shifts of the supporting mat, thereby preventing positional shifts of the supporting mat in conjunction with fastening work of the metal plate from occurring. Such recovering means can be structured by a recess formed at an end of the casing, plural spaces formed of a crank shaped supporting mat, or a space formed at an overlapped portion at which each end of the casing is overlapped to each other.
