ABSTRACT:
An exhaust gas cleaning apparatus comprises a honeycomb core body adapted for carrying an exhaust gas cleaning catalyst and fitted in a tubular metal casing. The carrier body is formed by rolling or laminating a sheet-like band and a corrugated band together. The carrier body has a recess in its outer peripheral surface so that the outer peripheral surface is kept out of contact with an inner surface of the casing. This recess effectively absorbs or relaxes the stress due to large thermal strains acting between the outer peripheral surface of the carrier body and the inner surface of the casing.
