CATALYTIC CONVERTER FOR EXHAUST-GAS CLEANING USE AND METHOD OF ASSEMBLING SAME Abstract of the Disclosure The converter casing includes a hollow cylindrical body in which a monolithic catalyst substrate is supported by a wire-mesh cushioning element. Secured to the casing body are a pair of holding fixtures which are each fitted with an end cushioning element engageable with the adjacent end face of the catalyst substrate to hold the latter against axial displacement. The casing body includes a smaller-diameter portion, at least one larger-diameter portion and a sloped shoulder portion interposed there- between. The holding fixtures are fixed to the larger- diameter or other end portions of the casing body in spaced relation to the cushioning element held between the catalyst substrate and the casing body. Such casing structure reduces the danger of the catalyst substrate being damaged or broken under vibration or shock to a minimum thereby to enhance the durability of the substrate and enables reali- zation of a particularly compact and inexpensive catalytic converter.
