The engine exhaust treatment device includes: an SCR catalyst case (3) housing an SCR catalyst; an SCR exhaust inlet pipe (14); and the urea water injector (16) and the nozzle portion (16a) of the urea water injector (16) is directed toward an inside of the SCR exhaust inlet pipe (14). An exhaust deflector (36) is provided in the SCR exhaust inlet pipe (14) and the exhaust deflector (36) is mounted to an inner peripheral face (37) of the SCR exhaust inlet pipe (14) on an exhaust upstream side of the urea water injector (16) so that exhaust (15) flowing toward the nozzle portion (16a) of the urea water injector (16) is deflected by the exhaust deflector (36) and diverted from the nozzle portion (16a).
