Abstract
A tandem support structure for an exhaust gas purifying catalyst comprises a sleeve, a first honeycomb disposed on an upstream side of exhaust gases, and a second honeycomb disposed on a downstream side of exhaust gases at a position axially separated from the first honeycomb. The second honeycomb is fixed to the sleeve, and the first honeycomb is held by a holding member which axially extends in an upstream direction from said second honeycomb, without contacting the sleeve. Since an air layer exists between the first honeycomb and the sleeve, heat radiation from the first honeycomb is prevented and temperature rising characteristics of the first honeycomb are improved.
