PROBLEM TO BE SOLVED: To provide an EGR device for an internal combustion engine with a supercharger, which can efficiently eliminate water drops produced in the inside of an EGR pipe and can prevent the corrosion of the EGR pipe. SOLUTION: In this EGR device 1 arranged in an internal combustion engine 5 with a supercharger having a supercharger 7 rising pressure of intake air, the EGR device 1 has an EGR pipe 10 equipped with an EGR cooler 3 for cooling EGR gas. One end of this EGR pipe 10 is connected to the intake passage 51 of the internal combustion engine 5, and also the other end thereof is branched into a main pipe 11 and a bypass pipe 12, and the main pipe 11 and bypass pipe 12 are respectively communicated with the exhaust passage 51 of the internal combustion engine 5 and the outside. Opening/closing valves 21, 22 opening/closing the communicating conditions of the main pipe 11 and bypass pipe 12 are arranged in the EGR pipe 10. |
