PROBLEM TO BE SOLVED: To provide an exhaust emission control device which can improve productivity by simplifying joint between parts using a shaft center, correspond to a variety of flow speeds of an exhaust gas from the time of idling to full- open driving, improve durability through uniform use of an entire catalyst support and prevent deterioration of the catalyst. SOLUTION: According to the present invention, in an exhaust emission control device 3 provided with an inlet part 8 and an outlet part 9 of an exhaust gas 7 and a catalyst support 10 provided between these inlet part 8 and outlet part 9, a chamber part 11 is provided between the inlet part 8 and the outlet part 9, shaft centers C1 and C2 of the inlet part 8 and the outlet part 9 are aligned and the catalyst support 10 is arranged within the chamber part 11 dislocated from the shaft centers C1 and C2 of the inlet part 8 and the outlet part 9. |
