PROBLEM TO BE SOLVED: To provide an exhaust emission control device including a casing mounted in the middle of an exhaust system while embracing an exhaust emission control catalyst, and a plurality of sensors installed on at least one of the inlet and outlet sides thereof, for actualizing the mounting of the sensors at optimum positions and thus improving the detecting accuracy.SOLUTION: The exhaust emission control device includes a casing 4 mounted in the middle of the exhaust system while embracing an oxidation catalyst 2 (the exhaust emission control catalyst), and a plurality of sensors 9 installed on at least one of the inlet and outlet sides of the casing 4. A sensor boss 12 is integrated therewith for supporting the sensors 9 fitted therethrough. The sensor boss 12 is commonly used for the sensors 9 to be mounted on the casing 4. |
