Catalyst carrier holding member, method of making the same and catalyst converter

摘要

The present invention provides a catalyst carrier holding member (101,103) to be fitted into a gap between a catalyst carrier and a casing accommodating the catalyst carrier. The catalyst carrier holding member (101,103) includes a three-dimensional molded article having flexible inorganic fiber and an inorganic expansive admixture, if desired. The flexible inorganic fiber is bound together by a binder in a compression-deflected state. A surface in contact with the catalyst carrier is shaped substantially in conformity to the outer shape of the catalyst carrier, and a surface in contact with the casing is substantially in conformity to the inner shape of the casing. The catalyst carrier holding member has a thickness equal to or larger than the gap.
