<p>PURPOSE:To relax the thermal stress and improve the durability in the first, to be high in the rigidity and be superior in the strength in the second to improve the purifying performance of the catalyst and be superior in the purifying efficiency of the exhaust gas by generating a turbulent flow in a passing exhaust gas and reacting much more with the catalyst in the third, and to enable to simply manufacture thereof without increasing the cell number and the volume and to realize without generating the problem on the cost in the fourth. CONSTITUTION:A so-called helical form of the corrugated sheet 5, where the adjacent corrugated forms are different and also at least the one side of them is provided with an inclination with respect to a belt-like side 7, is alternately wound and connected. The carrier 6 has about a honeycomb structure being an assembly body of hollow cylindrical cells 10 and the total body has a roll form of a true circle, etc., and the catalyst is stuck to it.</p> |
