Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine having a simple configuration and capable of maintaining an injection form preventing injection fuel injected by a fuel injection valve from adhering to a wall face of an injection passage and successfully maintaining fuel addition to a catalyst. SOLUTION: A fuel addition injector (20) for adding fuel to an oxidation catalyst (12) is provided in a branch (10a) of an exhaust pipe (10) via a support member (22). The cylindrical injection passage (26) is formed in the support member and a groove (28) is formed on a side wall face of the injection passage. COPYRIGHT: (C)2009,JPO&INPIT
