母体。[Scope of Claim for Utility Model Registration] 1. A large number of mesh-like passages in the axial direction produced by stacking flat strips and corrugated strips of thin metal plates and winding them in a spiral shape. In a metal support base for supporting an exhaust gas purifying catalyst, which is configured by fixing a laminate having pore passages inside a cylindrical metal case, the cylindrical metal case is connected to an outer case and an outer case. 1. A metal support base for supporting an exhaust gas purifying catalyst, comprising at least one internal case, and the laminate is fixed inside each case. 2. According to claim 1, the outer diameter of the inner case is large enough to expand the diameter of a cavity formed at the center of the winding of the laminate fixed in the outer case. metal carrier. 3. The pitch width between the peaks (troughs) of the corrugated strips of the laminate fixed inside the inner case is smaller than the pitch width of the corrugated strips of the laminate fixed inside the outer case. 3. The metal support base according to claim 1 or 2, which is a metal carrier. 4. Claims 1 to 4, wherein the material of the strip of the laminate fixed in the inner case has better heat and corrosion resistance than the material of the laminate fixed in the outer case.
The metal supporting matrix according to any one of Item 3. 5. The metal support base according to any one of claims 1 to 4, wherein at least one end of the external case is provided with one or more ribs.
