<p>It is an object of the present invention to provide an exhaust gas purifying apparatus obtainable by a simple method, the exhaust gas purifying apparatus (10) being capable of holding and fixing an exhaust gas treating body without an increase in the bulk density of the holding sealing material after the assembly thereof or the application of the excessive external force onto the holding sealing material.
An exhaust gas purifying apparatus (10) of the present invention includes: an exhaust gas treating body (40) having a pillar shape, in which a plurality of cells (41) are longitudinally disposed in parallel with one another with a cell wall (42) interposed therebetween; a metal casing housing (20) around the exhaust gas treating body; and a holding sealing material (30) provided between the exhaust gas treating body (40) and the metal casing (20) to hold the exhaust gas treating body (40), the holding sealing material (30) including an inorganic fiber aggregated body, wherein the metal casing (20) has a corrosion area (22) at least on a part of an opposite surface that is included in an inner surface of the metal casing (20) and is facing to the holding sealing material (30), the corrosion area (22) being formed by a corroded base material of the metal casing (20).</p> |
