Monolith supporting structure for use in catalytic converter

In a catalytic converter having a monolith held in a housing,

• a monolith supporting structure for resiliently holding said monolith in said housing, comprising:
• an annular seat structure defined by said housing;
• and
• an annular resilient washer made of wire mesh, said washer being put on said annular seat structure for supporting thereon a circular peripheral edge of said monolith, said washer having a first surface put on said annular seat structure and a second surface for directly supporting thereon said circular peripheral edge of said monolith;
• wherein said annular resilient washer has a generally rectangular cross section and has a chamfered surface around a circular inner surface thereof, so that a width of said second surface of said annular resilient washer is smaller than that of said first surface of the washer, said chamfered surface being positioned radially inside the circular peripheral edge of said monolith when said annular resilient washer is compressed by said monolith by a certain degree.
