PURPOSE:To prevent the damage of the peripheral part of the honeycomb by a method wherein the inner peripheral part side of the end part of the honeycomb, with respect to the edge face thereof, is more strongly pinched than the outer peripheral part thereof by an elastic support member for supporting the edge part of the ceramic honeycomb catalyst. CONSTITUTION:The edge face peripheral part 7 of the ceramic honeycomb catalyst 4 provided in an exhaust pipe for the internal-combustion engine is cut off toward the outer periphery thereof and when a force P is imposed to the elastic support member 1 pinching this part under abutting against there, the stress caused thereby becomes smaller as it is closer to the rim of the periphery. According to this constitution, the damage at the periphery, tends to occur in the honeycomb catalyst, may be prevented and the catalyst may be pinched by the strong force P, thereofore, the catalyst will never be moved. |
