摘要 |
Described is an exhaust gas cleaning metallic substrate of the structure that three metallic honeycomb bodies are successively arranged within a metallic casing. Among the three metallic honeycomb bodies, (i) the metallic honeycomb bodies at front and rear positions have each been constructed by fixing a planar and corrugated bands as constituent members of said metallic honeycomb body at at least some of points of contact therebetween and also an outer peripheral wall of the metallic honeycomb body and an inner peripheral wall of the metallic casing at at least some of points of contact therebetween, and (ii) the metallic honeycomb body at a middle position has been constructed without fixing a planar and corrugated bands as constituent members of said metallic honeycomb body at points of contact therebetween and also an outer peripheral wall of the metallic honeycomb body and an inner peripheral wall of the metallic casing at points of contact therebetween. |
