Claims

[Claims for Utility Model Registration] 1. A honeycomb core having a large number of mesh-like ventilation holes in the axial direction, which is manufactured by stacking flat strips and corrugated strips of thin metal plates so that they are in contact with each other. In an exhaust gas purification device for supporting an exhaust gas purification catalyst, the two honeycomb cores are spaced apart and fixed in a cylindrical metal case that is open at both ends and has an enlarged diameter portion. The outer circumferential surface of the honeycomb core body near the opening of the metal case is fixed to the inner wall surface of the metal case, and the outer circumferential surface of each honeycomb core body near the separated part does not come into contact with the inner wall surface of the metal case. Characteristic exhaust gas purification device. 2. Claim 1, wherein the honeycomb core body is manufactured by stacking flat strips and corrugated strips so that they are in contact with each other, and then winding them together in a spiral shape and laminating them.
The exhaust gas purification device described in . 3. Claim 1, wherein the honeycomb core body is manufactured by laminating flat strips and corrugated strips in a layered manner.
The exhaust gas purification device described in . 4. The exhaust gas purification device according to claim 1, wherein a spacer is provided on the outer circumferential surface of the honeycomb core body in the vicinity of the separated portion, and is fixed to the outer circumferential surface and abuts on the inner wall surface of the enlarged diameter portion of the metal case. . 5. The exhaust gas purification device according to claim 4, wherein the spacers are provided at predetermined intervals in the circumferential direction. 6. The exhaust gas purification device according to claim 4, wherein the spacer is provided over the entire circumference in the circumferential direction.
