ることがあった。As the catalyst holder 94, for example, a cordierite carrier having a honeycomb cross section is used, and a catalyst such as platinum is carried on the inner surface of the honeycomb. The inorganic sheet layer 93 and the metal net 931
Protects the catalyst holder 94 from damage when the catalyst holder 94 comes into contact with the outer metal shell while the vehicle is running, and the buffer seal material 93 leaks exhaust gas from between the shell 92 and the catalyst holder 94. It is used to prevent this.
As the inorganic sheet layer 93, generally used is a mixture of silica / alumina ceramic fiber and unexpanded vermiculite, which is formed into a sheet and has a thermal expansion property. By the way, in recent years, for the purpose of cost reduction or the like, without using the metal net 931 as shown in FIG. 4, the catalyst holder 94 and the metal shell 92 are covered with the inorganic sheet layer 932 so as to cover the entire periphery of the catalyst holder 94.
The converter structure used between and is being studied. However, in the converter structure in which the inorganic sheet layer 932 is used to cover the entire periphery of the catalyst holder 94, when an inorganic sheet is used as in the conventional case, the catalyst holder is strongly strengthened by the expansion pressure of the sheet material. The fixed result,
Repeated heating and cooling while the catalyst holder was firmly fixed sometimes caused stress due to the relative thermal expansion difference between the catalyst holder and the shell 92, and the catalyst holder was sometimes damaged. .

本発明を完成した。The problems caused by the damage of the catalyst holder are that the durability of the inorganic sheet 932 is reduced, the back pressure is increased due to the displacement of the cell, and the catalyst is damaged by vibration. It is considered that the holders rub against each other and become powdered, and the exhaust gas purification performance and engine performance deteriorate. Therefore, the inventors of the present invention have conducted further diligent research, and the cause of cracking of this new catalyst carrier is
The heat of the exhaust gas causes the metal shell 92 to linearly expand, and the tensile stress is applied to the catalyst holder 94 via the inorganic sheet 932. Therefore, the exhaust gas is sealed without damaging the catalyst holder. In developing a seal structure for an exhaust gas purification converter that can
The present invention has been completed.

機シート材で狭設して使用することが好ましい。Next, as the solid lubricant, it is preferable to use a material having a friction coefficient of 0.5 or less and a melting point of 1000 ° C. or more. Such solid lubricants include mica,
Depending on the synthetic mica and the conditions, sheet materials such as expanded graphite, molybdenum disulfide (MoS 2 ), boron nitride (B
N) and other coating materials, and boron nitride, which does not change the friction coefficient even at high temperatures, is preferable. This is a flaky layered powder in which the main crystal structure of the powder is a hexagonal system, and the bonding between each layer is due to Van der Waals force, and the bonding force is very weak and against shearing force. Since it has cleavability, excellent solid lubricity can be obtained. Therefore, by forming a catalyst holder and a shell that covers the outside of the catalyst holder through the inorganic sheet layer and the solid lubricant layer, the tensile stress exerted by the metal shell on the catalyst holder is suppressed, and cracks occur. The problems such as are solved. Here, the solid lubricant layer is installed on the surface of the inorganic sheet material, the metal shell or the catalyst holder, and in consideration of the assemblability, when a sheet material such as mica is used as the solid lubricant layer, it is optional. It is considered optimal to fix it on one of the surfaces with an adhesive method. When the heat resistance of the solid lubricant layer is severe, it is preferable that the solid lubricant layer is used by narrowing it with inorganic sheet materials.

It is difficult to provide a coating layer and a sheet material layer having a thickness of less than 0.1 mm, while if the thickness is 1.0 mm or more, the thickness of the inorganic sheet material is reduced and the gas sealing property is significantly deteriorated. Is 0.1 to 1.0 m
It is preferably in the range of m.
