PROBLEM TO BE SOLVED: To provide an exhaust recirculation device capable of reducing a problem attributable to a loss of pressure while securing the cooling performance of internal EGR gas when installing a heat exchanger in an intake manifold.SOLUTION: Partition wall members 30b and 30d are constituted in a manner that one side that is directed from a heat exchanger 26 side to an intake port 24a and 24d side is cut out, and a partition wall member 30c is constituted in a manner that both sides that are directed from the heat exchanger 26 side to an intake port 24b and 24c side are cut out. An effective area is increased by providing the partition wall members 30b-30d of such a cutout constitution. The effective area is decreased in the heat exchanger 26 but increased in the neighborhood of the outlet (namely, the neighborhood of the upstream of a gas path 32) of the heat exchanger 26. |
