ABSTRACT:
A heat-insulating resilient supporting and sealing member inserted in a monolithic type catalytic exhaust gas purifier of generally elliptical cross section between an inner wall of a casing and the outer periphery of a monolithic catalyst housed in the casing such that a thicker portion of the supporting and sealing member is disposed at a smallest cross dimension region of the casing, and a thinner portion of the supporting and sealing member is disposed at a largest cross dimension region of the casing, so that the bulk density of the member at the operating temperature of the catalytic purifier is approximately constant around the periphery of the member.
