Abstract

PURPOSE:To secure uniform surface pressure of a flange by providing tapered parts around the outer peripheries of coupling flanges of an exhaust manifold and a catalyst converter, and clamping and coupling both tapered parts by means of taper metal fittings engaged with the tapered parts. CONSTITUTION:To the flange of the lower end of an exhaust manifold 1, the upper flange of a casing of the catalyst converter accommodating therein a catalyst 8 is coupled. Upon coupling, one-sides of both flanges are coupled by means of a bolt 4 as heretofore, and other sides thereof are clamped by fitting metal fittings 5 inner surfaces of which form tapered shapes 5a and 5b into the tapered parts 13 and 14 on the outer surfaces of both flanges, and screwing the bolt 6 in the screw hole of the flange.

Bolts are tightened using metal fittings, and a mating screw hole for tightening the Taber metal fitting is bored in either of the flanges.

The tightening screw hole of the tapered metal fitting is drilled in the flange of the converter or the 7 langes of the case, and the force acting on the tapered surface tightens both 7 langes! Since the 1 mating surfaces are in close contact with each other, it is possible to make the joint part more compact, and by tightening the taper metal fitting, which is a small piece of metal fitting, to the 7 lange screw hole KIL, there is no problem like the clamp method where the joints are tied together. It has the advantage of being able to select the rigidity of the container due to the rigidity of the tapered metal fittings and the strength and verticality of the bolts.
