ある。2. Description of the Related Art There is a sandwich type in which a mesh is arranged between each gas flow hole of a pair of ring-shaped members constituting a gasket and both members are bonded with an adhesive. In addition, the hole edge of each gas flow hole that opens on one side of the disk is lowered by one step to form a concave portion, the mesh is housed in this concave portion, and the peripheral edge portion of this mesh is adhered to the facing surface of the hole edge portion with an adhesive. There is also a storage type that is glued.

製作の手間の問題を解決したものである。In the sandwich type, the adhesion is likely to be incomplete, and if this happens, the mesh will shift due to the gas flow resistance and the filter function will not be fulfilled. In the case of the storage type, in addition to forming a recess at the edge of each gas flow hole, it also takes time and effort to bond each mesh separately to the facing surface of the recess, and when gas flows in the direction toward the step surface. There is no problem, but when flowing in the opposite direction, the adhesive surface easily peels off due to the resistance. The present invention solves the problems of mesh displacement and peeling, and manufacturing labor by integrating the mesh with the main body by vulcanization molding.

One side 24 side includes one larger than the other side 25 side. In this way, even if the mesh 21 is repeatedly deformed due to the resistance of the fluid, there is no sharp corner and the mesh 21 does not break. Further, when the fluid reciprocates through the mesh 21, the elasticity of the main body 1 counteracts the movement of the fluid to peel the mesh 21 from the annular washer 22, thereby preventing breakage and peeling.

In this case, the portion of the mesh 21 that has melted due to welding and loses the mesh function moves away from the inner peripheral edge of the annular washer 22, so that the filter effect is enhanced. Further, since the welded portion 23 is covered with the elastic main body 1, the stress concentration on the welded portion 23 due to the resistance of the fluid is reduced to prevent the mesh 21 from peeling from the annular washer 22.
