PROBLEM TO BE SOLVED: To provide an exhaust gas recirculating device of an internal combustion engine, capable of restraining sticking of a deposit in an intake passage such as the compressor inside. SOLUTION: This exhaust gas recirculating device of the internal combustion engine 1 has an EGR passage 10 for recirculating a part of exhaust gas from an exhaust passage 5 to the intake passage 4 on the upstream side of a compressor 7a of a turbocharger 7, and an EGR valve 12, and has a PCV valve 22 capable of respectively adjusting a first blow-by gas quantity flowing in a first blow-by gas passage 21a and a second blow-by gas quantity flowing in a second blow-by gas passage 21b, by respectively connecting the crankcase inside and the intake passage 4 on the upstream side of the compressor 7a by the first blow-by gas passage 21a, and the crankcase inside and the intake passage 4 on the downstream side of the compressor 7a by the second blow-by gas passage 21b. The PCV valve 22 is controlled so that the second blow-by gas quantity increases more than the first blow-by gas quantity, when opening the EGR valve 12. COPYRIGHT: (C)2008,JPO&INPIT
