ABSTRACT:
An exhaust gas cleaning apparatus comprises one or more honeycomb core bodies for carrying an exhaust gas cleaning catalyst and fitted in a tubular metal casing. The metal casing has an outer wall which is axially expandable and contractible so as to follow the stress due to thermal strains acting on the honeycomb core bodies inside, thereby remarkably improving the apparatus in durability and vibration resistance.
