PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of suppressing movement and damage of a catalytic cassette due to thermal expansion and vibration.SOLUTION: An exhaust emission control device 1 comprises a catalytic reactor 12 to which plural catalytic cassettes storing NOx catalyst as catalyst therein can be detachably attached therein. In inside of the catalytic reactor 12, the respective catalytic cassettes are inserted from a first opening 13a and a second opening 13b as openings so as to be positioned adjacent, and a wedge-like member is inserted into a gap G between the respective catalytic cassettes. Then a first lid member 26 and a second lid member 27 for occluding the first opening 13a and the second opening 13b are attached for energization of the respective catalytic cassettes. |
