Abstract

PURPOSE: To prevent by-passing of exhaust gas through catalyst converter, by fitting seal plates at opposite openings of a hollow space formed between monolithic catalyst and its container, and press fitting ceramic fibers into the hollow space.
CONSTITUTION: Annular metal seal plates 6a, 6b are disposed around the end face of monolithic catalyst 1 in the manner keeping contact with the same, and fabrics 7a, 7b of fine metal wires shaped in an annular form are press fitted in respective spaces formed between plates 6a, 6b and mating projections 51a, 51b of a holding member, so as to absorb axial vibration of the monolithic catalyst 1. At opposite openings of hollow space 4 formed between outer peripheral surface of monolithic catalyst 1 and inner peripheral surface of container 2, annular compression-shaped elements 8a, 8b made of ceramic fiber of alumina or the like are fitted between seal plates 6a, 6b and opposite end portions of metal net 40. Here, the compression- shaped elements 8a, 8b are urged onto the outer peripheral surface of monolithic catalyst 1 and the inner peripheral surface of container 2, so that leakage of exhaust gas into hollow space 4 can be prevented by the element 8a.
