PROBLEM TO BE SOLVED: To provide an exhaust emission purifying device, in which a mixer for mixing a reducer injected from a reducer feeding device into an exhaust gas passage with an exhaust gas is arranged on the upstream side of a catalytic converter, wherein the exhaust resistance of the mixer is suppressed to a relatively low value.SOLUTION: A mixer 14A is equipped with a plurality of wall parts 22, 23, 24, 25 and 26 extending in parallel along an exhaust gas flowing direction 21 in an exhaust gas passage 19 so that a reducer r injected from a reducer feeding device 15 may impinge individually, and the surface areas of those wall parts 22 to 26 may become gradually larger as they become more distant from the reducer feeding device 15. |
