An EGR device includes a first cooling passage that introduces a flowing medium discharged from an engine into a main radiator so that the flowing medium is cooled therein, and then returns the flowing medium to the engine, and a second cooling passage that introduces a part of the flowing medium cooled in the first cooling passage to a sub-radiator so that the flowing medium is further cooled therein. The second cooling passage introduces the flowing medium to an EGR cooler to return the flowing medium, which is discharged from the EGR cooler, to the engine. |
