description To facilitate the vaporization of additives added upstream of a selective catalytic reduction device and to suppress their precipitation.A mixing device includes: a case surrounding a blowing section, through which an exhaust gas is blown out, of a filter or a catalyst; an upper pipe segment having an opening formed therein, the opening facing a direction facing the blowing section, the upper pipe segment being tilted relative to the vertical direction so that the more the upper pipe segment goes vertically downward, the closer it gets to the blowing section in a region facing the blowing section within the case; a lower pipe segment bent from a lower end of the upper pipe segment, the lower pipe segment being tilted relative to the vertical direction so that the more the lower pipe segment goes vertically downward, the further away it gets from the blowing section, the lower pipe segment extending out from the case and being connected to a selective catalytic reduction device; and an injector attached to the case, the injector injecting a liquid additive toward an area faced by the opening, the area being located outside the upper pipe segment in the case.
