PROBLEM TO BE SOLVED: To provide a mixer for an exhaust emission control device which can be easily manufactured while minimizing the number of components.SOLUTION: A mixer for an exhaust emission control device for mixing a reductant agent r and exhaust gas g is made by a plate press of a single plate material, and includes a rim 10, a hub 11 arranged in a center of the rim 10, and a plurality of blades 13 interposed between the rim 10 and the hub 11. Each of the blades 13 is constituted by a first blade half part 13a integrally connecting the rim 10 and the hub 11, and a second blade half part 13b integrally continued to the first blade half part 13a and the rim 10, separated from the hub 11 so as to form a first slit 12a therebetween, and separated from the first blade half part 13a of the adjacent blade 13 so as to form a second slit 12b therebetween, and the second blade half part 13b is offset with respect to the first blade half part 13a in an axial direction, and thus, the first and the second slits 12a and 12b are widened in the axial direction. |
