The threaded portion 15 is a bolt that fastens the i0 distribution manifold l and the case 2. That is, a cushion sheet 4 is placed on the upper m outer side of the catalyst body 3 on the exhaust gas inlet side.
A sealing material 7 and a retainer 6 are attached to the head bearing surface of the center bolt 12 on the gas outlet side of the catalyst 3.
1 and the threaded portion 1411L of the boss 13 using the pipe IO passing through the through hole 9 in the center of the catalyst body 3 as a guide.
By screwing together the centering bolt 12, the bolts 12 are connected and fixed. By doing this, the total length of the catalyst body 3, the height of various inclusions, the elastic modulus, the pipe lO
By selecting the overall length, etc., it is possible to match the excessive holding and fixing strength of the skeleton catalyst body 3. Also manifold l
For case 2, fix the flange surface to the contact surface by tightening the bolt 15. Therefore, the upper and lower frame cushion sheets 4 and gaskets 5 of the catalyst body 3 provide a vibration-absorbing retainer, and the outer circumferential direction is gas-sealed by the sealing material 7, thereby improving the retention durability and purification performance of the manifold converter. ti can be maintained.

It is possible to improve productivity. Moreover, by abolishing the press-fitting process of the catalyst body, restrictions on the dimensional accuracy of the overall length and outer diameter of the catalyst body are lifted, and since the tightening of the center bolt and the U-VIVE act as a guide, assembly is easy. The tightening torque is stable and can be easily tightened even when the catalyst layer is made of a ceramic body with low strength, and it is also easy to assemble a plurality of catalyst layers. As for the housing, the effects of this invention are extremely large, such as improved storage and retention due to these improvements, and improved reliability. −
