Abstract

PURPOSE:To facilitate press assembly work of a gas sealing member, by enclosing the periphery of the gas sealing member of asbestors or the like with metal foil, winding the gas sealing member to the periphery of a monolithic catalyzer and press inserting the member into a case with the catalyzer. CONSTITUTION:When a monolithic catalyzer vessel is assembled, firstly a wire net 4, for radially supporting a catalyzer 2, is wound to the periphery of the monolithic catalyzer 2, and a gas sealing member 1 is rolled on an exhaust gas introducing side end of the catalyzer 2. This gas sealing member 1 is formed in such a manner that a gas sealing material 1a of asbestos or the like is compression formed and enclosed with metal foil 1b to its periphery. Then said monolithic catalyzer 2 is press inserted by using a press insertion jig 7 into a case 3, mounted with cushions 5 to an exhaust gas discharged side stepped part, through a guide member 6, to complete assembly work of the monolithic catalyzer vessel.
