Abstract
An exhaust emission control device is provided which is compact in size and has favorable dispersibility of exhaust gas from a muffling structureto an oxidation catalyst. The muffling structurearranged upstream of the oxidation catalyst in a direction D of gas flow has a dispersion platefor dividing the interior of the casinginto dispersion chambersandupstream and downstream in the direction D of gas flow, respectively, and an inner pipeinserted from outside of and into the chamberand with a tip end fixed to the dispersion plateand circumferentially formed with poresandhaving diameters gradually reduced in the order in the direction D of gas flow from upstream to downstream. The dispersion platefacing the dispersion chambersandis formed with a plurality of radially-outward-larger-diametered and radially-inward-smaller-diametered poresand
