A catalytic converter effective to prevent damage or breakage of a catalytic element for improved durability. A catalytic element is housed in a casing and a pair of first and second end members are fitted into the opposite end portions of the casing so as to support the opposite end portions of the catalytic element via first and second end cushions. The first and second end cushions have, when in a free state, a rectangular cross section and inner diameters gradually increasing toward the catalytic element. The first and second cushions are compressed, when the catalytic converter is assembled, by the first and second end members to be fitted and held at their respective inner end portions between the inner circumferential surface of the casing and the outer circumferential surfaces of opposite end portions of the catalytic element.
A catalytic convertor comprising a casing having opposite end portions and an inner circumferential surface, a catalytic element housed in said casing and having opposite end portions with outer circumferential surfaces, first and second end cushions adjacent said opposite end portions of said catalytic element having inner end portions, and first and second end members fitted into said opposite end portions of said casing and supporting said opposite end portions of said catalytic element via said first and second end cushions, said first and second end cushions being constructed such that in a free state each has a rectangular cross section and inner diameters which gradually increases toward said catalytic element, said first and second end cushions being compressively fitted between said first and second end members and said opposite end portions of said catalytic element and said respective inner end portions of said first and second end cushions being held between the inner circumferential surface of said casing and the outer circumferential surfaces of the opposite end portions of said catalytic element.
