The present invention, in the element (尿素) mixing an aqueous solution (mixing) device, to suppress the urea aqueous solution is attached to the inner wall of the exhaust pipe to decrease the flow passage (流 路) resistance in the exhaust pipe. The urea aqueous solution mixing device is provided with an exhaust pipe (4B) and the injector (5) and the mixing pipe (6) and the inner pipe 7, a distribution unit 20. An exhaust pipe (4B) is, has an elbow portion (elbow part) (10) and a straight portion 11 having a curved portion. Injector 5, is installed in the elbow section 10, the urea aqueous solution is injected. Mixing pipe (6), the injector (5) a plurality of openings (6a) formed in the outlet portion and the outer peripheral surface formed with an interval between the inner wall of the exhaust pipe (4B) is arranged to cover the periphery of the urea aqueous solution, which is injected from have. The inner tube (7), the exhaust gas, the inner and outer periphery is arranged on the straight portion 11 of the exhaust pipe (4B) that is available for distribution. Distribution unit 20, is formed between the inner wall of the mixing pipe (6) of the outlet portion and the exhaust pipe (4B), and guides the exhaust gas in the inner tube (7).
