PROBLEM TO BE SOLVED: To provide a mixing device capable of atomizing a reducing agent sprayed from an addition valve and of introducing to an exhaust gas downstream side.SOLUTION: A blade 31 constituting a mixing device is provided with a trapping part 40 for trapping an urea water in an exhaust flowing toward the exhaust downstream side from an exhaust upstream side along the surface 34 of the blade 31. The urea water trapped by the trapping part 40 is atomized through a slit 43 allowing a trapping space 41 and a space in the exhaust downstream side from the trapping part 40 to communicate with each other and is passed through the exhaust downstream side. |
