摘要： A gas duct having a honeycomb structure includes: a metal case, a honeycomb structure accommodated in the metal case, a holding member placed between the outer surface of the honeycomb structure and the inner surface of the metal case, and a cone fitted to the inner surface of the metal case at one or both openings of the metal case, wherein the circumference of one or both end faces of the honeycomb structure is allowed to abut on the cone. The gas duct having a honeycomb structure can effectively utilize the whole volume of the honeycomb structure, is low in pressure loss, and inexpensive.

摘要： A gas duct includes a ceramic honeycomb structure includes a metal case, a ceramic honeycomb structure accommodated in the metal case, and a holding member placed between the outer surface of the ceramic honeycomb structure and the inner surface of the metal case. The holding member has, at the two ends, to-be-connected areas engageable to each other and is wound round the outer surface of the ceramic honeycomb structure in such a way that the to-be-connected areas of the two ends are engaged to each other and that the connected area and its vicinity face the partition wall of each cell constituting the honeycomb structure. In the gas duct, even when the ceramic honeycomb structure has thin partition walls, the honeycomb structure is not broken when it is accommodated in a metal case, i.e. during the canning.
