In an exhaust emission control device, a casing 7, which accommodates particulate filter 5 as a post-treatment device through which exhaust gas 3 is passed for cleanup, has an outlet connected with a downstream exhaust passage 12 extending substantially perpendicular to an axis of the casing 7. In order to realize compactness in size of the whole structure without increase of exhaust resistance, an outer chamber 11 encases the casing 7 in a required range to provide required spacing for an open end 7a and an outer periphery 7b of the outlet of the casing 7. The outlet chamber 11 intervenes between the outlet of the casing 7 and the downstream exhaust passage 12. |
