PURPOSE:To provide an inexpensive holding metal fitting imparting no damage to a catalyst, by dividing a plane for clamping the catalysts of outer and inner metal fittings in a meandering line shape, and providing a catalyst to the plane part by inserting the same between both metal fittings in a state opposedly contacted therewith. CONSTITUTION:The plane part 11 of a holding metal fitting 10 made of a heat resistant stainless steel plate with a thickness of 0.3-0.5mm. is cut along a meandering line 12 to be divided into an outer metal fitting 13 and an inner metal fitting 14. A foldable fixing pawl 15 is provided to the outer metal fitting 13. The inner metal fitting and the outer metal fitting are assembled and fixed which the center of the inner metal fitting 14 is aligned by the leading end of the fixing pawl 15. A catalyst 1 is provided to the plane parts of the outer metal fitting 13 and the inner metal fitting 14 by inserting the same between both fittings in a state respectively contacted therewith opposedly. |
