Abstract

PURPOSE:To positively prevent a leak of exhaust gas by providing cushion material, which is a lamination of heat resisting steel fiber and siliglass wool, for holding a honey-omb catalyst. CONSTITUTION:A honey-comb catalyst 4 is held elastically in a casing 5 via a cushion material 3. The cushion 3 is a lamination of fiber or a thin plate layer 1 of heat resisting steel and a siliglass wool layer 2. The high density of the cushion material prevens exhaust gas from leaking through the cushion without going through the honey-comb catalyst.
