<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device which is improved in handling workability in maintenance of an engine 70 or the like, in addition to the improvement in performance for controlling the emission of the exhaust of the engine 70. <P>SOLUTION: This exhaust emission control device includes: a plurality of gas emission control bodies 2 and 3 for controlling emission of the exhaust gas discharged from the engine 70; a plurality of inside cases 4 and 20, in which each of gas emission control bodies 2 and 3 is provided; and outside cases 5 and 21, in which each of the inside case 4 and 20 is provided. An outlet end inside case 4 on an upstream side of the exhaust and an inlet end inside case 20 on a downstream side of the exhaust are overlapped with each other to form a double-structure, and sensor boss bodies 110 and 113 for supporting exhaust gas sensors 63 and 109 are arranged on the outside surface of the outlet end or the inlet end of the double-structure, and the sensor boss bodies 110 and 113 are extended outside the outside case 5. <P>COPYRIGHT: (C)2011,JPO&INPIT |
