<P>PROBLEM TO BE SOLVED: To provide a fin deice for an exhaust emission control device capable of reducing a pressure loss and efficiently generating a swirl flow. <P>SOLUTION: Ther fin device 45 is provided in an exhaust passage 33 composed of a cylindrical casing 60. The fin device 45 includes a first plate member 71 and a second plate member 72. The first plate member 71 has a base plate 71a provided along the axis X of the casing 60, blades 71b, 71c, and a slit 71e. The second plate member 72 has a base plate 72a provided along the axis X of the casing 60, blades 72b, 72c and a slit 72e. The base plate 71a of the first plate member 71 is inserted into the slit 72e of the second plate member 72, and also the base plate 72a of the second plate member 72 is inserted into the slit 71e of the first plate member 71, thereby combining the first plate member 71 with the second plate member 72 in a cross shape. <P>COPYRIGHT: (C)2011,JPO&INPIT |
