される。 As shown in Fig. 1, a catalytic converter for purifying exhaust gas is constructed by supporting a monolithic catalytic converter b housed in a cylindrical case a in the radial direction or A pair of annular cushions d and d elastically hold it in the axial direction. Usually, the cushion d is made by rolling a metal mesh 21 made of thin metal wire into a cylindrical stockinette knitted shape from the periphery of one end toward the other end, as shown in FIG. The preform 22 is preformed into an annular shape with a spiral cross section as shown in FIG.

しも満足がいくとはいえないものであつた。 As the thin metal wire constituting the cushion d mentioned above, for example, a nickel alloy wire such as X-750 or a stainless steel wire such as SUS310S is used, but while the former has excellent elasticity at high temperatures, it has poor oxidation resistance. On the other hand, while the latter has excellent oxidation resistance under high temperatures, it cannot necessarily be said that it has excellent elasticity, so cushion d made from the former material cannot be said to be resistant to oxidation under high temperatures for a long time. When used, there is a risk of oxidation and burnout, and the cushion d made of the latter material gradually loses its elasticity and may become so-called sagging. Also, even if they are made of the same material, depending on the wire diameter, a small diameter wire will have excellent elasticity at high temperatures, but it cannot necessarily be said that it has excellent oxidation resistance, while a large diameter wire will have better elasticity at high temperatures. Although they have excellent oxidation resistance, they do not necessarily have excellent elasticity, and the same disadvantages as mentioned above may occur, so in any case, using either material or wire diameter However, as long as the cushion d is made of a single material, if the cushion d is exposed to high temperatures for a long time, there is a risk that it will oxidize and burn out or become stale. This was not necessarily satisfactory in terms of maintaining stable elasticity.

なるクツシヨン１が得られる。 FIG. 3 shows the cushion 1 and its manufacturing process in the first embodiment of the present invention.
The first metal mesh 2 is made of 750 material and is knitted into a cylindrical shape with thin metal wires that have excellent elasticity under high temperatures.
is rolled up from the periphery of one end toward the other end in the same manner as explained with reference to FIGS. As shown, a second metal mesh 4 made of SUS310S and knitted in a cylindrical shape from thin metal wires that have excellent oxidation resistance under high temperatures is placed around a preform 3 made of the first metal mesh 2. As shown in the figure, the cushion material 5 is formed by compression molding into an annular shape with a substantially rectangular cross section, so that the inner side becomes elastic at high temperatures as shown in the figure. A cushion 1 is obtained which has a double structure of an excellent first metal mesh 2 and a second metal mesh 4 having excellent oxidation resistance on the outside at high temperatures.

る。 In the cushion 1 having the above structure, the outer part that comes into contact with the air is made of the second metal mesh 4 which has excellent oxidation resistance, so it will not oxidize and burn out even at high temperatures, and is acid resistant. The first metal mesh 2, which is less oxidizable, is located inside and does not come into contact with air and does not oxidize. Therefore, even if the second metal mesh 4 becomes flat and loses its elasticity, the first metal mesh 2 will not oxidize. This elasticity is exhibited, and the cushion 1 maintains its elasticity as a whole.

ヨン１１としたものである。 Figure 4 shows the cushion 11 and its manufacturing process in the second embodiment of the present invention.As shown in the figure, the thin metal wire 12 is made of SUS310S and has a small diameter. Thin metal wires 13 are knitted alternately to form a cylindrical third metal mesh 14, and as in the conventional cushion, this third metal mesh 14 is knitted around one end of the periphery as shown in the figure. The cushion 11 is formed by rolling it up toward the end and preforming it into an annular shape with an overwound cross section as shown in the figure, and compression molding the preformed product 15 into an annular shape with a substantially rectangular cross section as shown in the figure. This is what I did.

発揮することができる。 In the cushion 11 having the above structure, the thin metal wires 12 with small diameters having excellent elasticity and the thin metal wires 13 with large diameters having excellent oxidation resistance are alternately knitted, so that the thin metal wires 12 can be used even under high temperatures. Alternatively, oxidation of the thin metal wires 13 can be kept to a minimum, and the cushion 11 can exhibit excellent elasticity as a whole.

Even if it is made of a metal mesh made by alternately knitting thin metal wires made of X-750,
The same effects as described above can be obtained.

The proposed monolithic catalyst holding cushion is
In a monolithic catalyst holding cushion that holds a monolithic catalyst with a large number of ventilation holes in the axial direction inside the case, the outer side of the metal mesh made of thin metal wires that has excellent elasticity under high temperatures is used. A cushion material made by winding a metal mesh knitted with fine metal wires that have excellent oxidation resistance under high temperatures, or a metal mesh made by alternately knitting the two metal wires, compression molded into an annular shape with a substantially rectangular cross section. Since the cushion is formed using a thin metal wire with excellent elasticity and a thin metal wire with excellent oxidation resistance, it has both properties and has excellent elasticity and oxidation resistance even at high temperatures. .
