構造を提供することを目的とするものである。The present invention solves the above-mentioned bolt arrangement problem by making it possible to tighten from the flange side, and also by using upper and lower through-bolts in combination to ensure uniform internal pressure and at the same time, to prevent assembly from being a nuisance to work. The purpose of this invention is to provide a coupling structure for a manifold converter.

徴とするものである。Therefore, in the structure of the present invention, in the seven-flange joint structure of the exhaust manifold and the converter case, the joint surfaces of both flanges have a taper that substantially matches the taper of the seven flanges from one direction outside the flanges. Bolts are tightened using metal fittings, and a mating screw hole for tightening the Taber metal fitting is bored in either of the flanges.

設けられたテーパ座である。In Fig. 3, l is a manifold, 2 is a converter case, 3 is a screw hole provided in the case 2, and 4 is a through port □ which is screwed and tightened into the screw hole 3. There is no big difference from the case in Figure 1 mentioned above, and 5 is the Kf84 figure in Figure 3, especially #! 5, a tapered metal fitting shouldering the tapered part 5 and 5b on a circular surface, 6 a bolt for fastening the tapered metal fitting 5, and 7 a screw for screwing the bolt 6 into the manifold l. 8 is the catalyst body, 9 is the Fi cushion carbon sheet, IO is the retainer, 1 is the fi gasket, 12 is the wire net bush*y, 13 is the taper provided in the 7 flange part of the flange of the The seat 14 is a tapered seat provided at the 7 flange portion of the case 2.

3 and 14 are provided, and the taper metal fitting 2 having portions 5m and 5b of the tee/() that almost matches the tapered surfaces of the seats 13 and 14 is provided with a taper fitting 2 of 1&m L, and the bolt 6 is inserted into the screw hole 7.
When engaged with K, the pushing force of the tapered surface acts as a component force in the axial direction of the 7 flange surface, and an effective surface pressure is maintained.

て、容品に納金強直を選定できる長所を有する。As described above, the present invention' provides for connecting both the 7 flange of the converter and the flange of the teeth by using a tapered metal fitting from one direction from the outside of both the 7 flange, and
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.
