<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine for preventing the leakage of additive flowing along the wall face of a passage, from between a seat portion and an exhaust pipe to the outside. <P>SOLUTION: The exhaust emission control device for an internal combustion engine includes fuel entry restricting means 35, 40 for restricting the entry of the additive P flowing along the wall face of the passage 26, between the seat portion 27 fixing a seat 24 and the walls of the exhaust pipe 15a. Thus, even when the additive P flowing along the wall face of the passage 26 moves between the seat portion 27 fixing the seat 24 and the walls of the exhaust pipe 15a, the fuel entry restricting means 35, 40 restricts the entry thereof to suppress the leakage of the additive P to the outside. <P>COPYRIGHT: (C)2009,JPO&INPIT |
