PROBLEM TO BE SOLVED: To provide an intake device configured to improved cooling performance and assemblability thereof.SOLUTION: An intake device 20 includes: a cover 21 connected to a cylinder head 32 having intake ports 311 therein, and having a plurality of branched passages 216 corresponding to the intake ports 311, a housing 22, and a cooling device 25 housed in a housing space 230 between the cover 21 and the housing 22. The cooling device 25 has a refrigerant conduit and a heat exchanging part, and a part of the refrigerant conduit is projected into the intake port 311 through the branched passage 216. Since the present invention has the heat exchanging part and a part of the refrigerant conduit is projected into the intake port 311, not only reheat of the intake air into the intake port 311 is suppressed, but also internal EGR gas can be efficiently cooled. Therefore, cooling performance of the intake device 20 can be improved. |
