つた。(Prior art) Conventionally, when supporting an exhaust gas purifying honeycomb in a casing, as shown in FIG. The sealing member 1 and the cushioning body 4 were attached to the intermediate part between the outer surface of the honeycomb 3 carrying the catalyst, and the cushion bodies 4, 4, which were compression-molded from a cylindrical metal mesh made of knitted metal wire, were inserted and supported at both ends. Since the sealing members were separate, assembly work was troublesome, and the sealing members were directly exposed to exhaust gas, making them easy to scatter.
（目的）
