Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent local boiling and thereby prevent crack generation in a tube by uniformly supplying cooling water inside a shell regardless of the position of a cooling water inlet port and a cooling water outlet port in an EGR cooler. SOLUTION: The EGR cooler 100 includes a hollow shell 110 having a cooling water inlet port 150 and a cooling water outlet port 160, and a plurality of tubes 140 disposed inside the shell 110 for passage of an EGR gas. The shell 110 includes a top face 113 and a side face 115. The cooling water inlet port 150 has a top face side inlet part 151 for introducing the cooling water from the top face 113 side, and a side face side introduction port 152 for introducing the cooling water from the side face 115 side. An adapter member 120 is disposed in the shell 110 for covering the cooling water inlet port 150. COPYRIGHT: (C)2009,JPO&INPIT
