<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of efficiently arranging catalysts close to each other when storing a plurality of catalysts inside an exhaust pipe for exhaust gas to circulate therethrough. <P>SOLUTION: The exhaust emission control device is provided in an exhaust pipe 20 for exhaust gas from an internal combustion engine to circulate therethrough, and includes: an oxidation catalyst 31 for oxidizing oxidizable components in the exhaust gas; and a particulate filter 32 that is arranged on a downstream side in an exhaust gas circulation direction of the oxidation catalyst 31, has a larger diameter than that of the oxidation catalyst 31, and collects particulate matter in the exhaust gas, wherein a spacer 10 is provided between the oxidation catalyst 31 and the particulate filter 32, and includes a fitting portion 10a to fit into a periphery 31c of the oxidation catalyst 31 and a plane portion 10b planarly contacting an end face 32a of the particulate filter 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
