Document Type and Number:
Japanese Patent JP3370940
Kind Code:
B2
Abstract:
A carrier supporting mat for exhaust converter for supporting a catalyst carrier is structured in having heat insulating mat members on an inner side as to direct contact with the catalyst carrier, an expansible mat member including a vermiculite on an outer side of the heat insulating mat members, and at least one heat insulating sheet member disposed among the mat members. Heats from exhaust gas is cut off by the heat insulating mat members, and expansion of a metal casing of the exhaust converter due to heats is followed by the expansible mat member. The sheet member creates sliding when the carrier supporting mat is lapped on the catalyst carrier because the mat members and sheet member can move correlatively and smoothly, thereby preventing wrinkles and tears from occurring.
