ABSTRACT:
In an exhaust gas cleaning apparatus, at least two honeycomb core bodies each carrying a cleaning catalyst are arranged, with at least one axial space therebetween, in a metal casing having an enlarged-diameter portion. The outer peripheral surfaces of the core bodies are fixed to the inner surface of the casing so that each core body is expandable and contractible axially. The result is that separation between each core body and the casing can be prevented, thus improving the durability. Further, an excellent cleaning performance can be achieved not only due to the heat insulating effect as well as the gas stirring effect by the enlarged-diameter casing portion, but also due to the gas turbulent effect by the inter-body space.
