Abstract
A monolithic catalyst converter comprises a monolithic catalyst retaining catalyst metal, a cylindrical metallic container receiving the catalyst therein, a radial shock absorbing member disposed in a space between the catalyst and the container, an annular metallic plate disposed in each of axially end surfaces of the catalyst, a retaining member fixed to an inner wall of the container so as to be opposed to the annular metallic plate, an axial shock absorbing member disposed between the annular metallic plate and the retaining member and at least one annular sealing member composed of a compact body obtained by compressing metallic fine wire fabric or ceramic fibers, which is disposed in the space under pressure. By disposing the annular sealing member, unpurified exhaust gas is prevented from flowing out of the space.
