PROBLEM TO BE SOLVED: To provide an EGR device in which such a problem is less caused that the accuracy of adjusting the amount and temperature of EGR gas is reduced resulting from a distribution resistance difference between a cooler passage and a bypass passage.SOLUTION: An EGR valve for adjusting the flow amount of exhaust gas to distribute in a cooler passage 43 is arranged in the cooler passage 43, and an EGR valve for adjusting the flow amount of exhaust gas to distribute in a bypass passage 44 is arranged in the bypass passage 44. An exit 43a of the cooler passage 43 is arranged so that its flow path axis A corresponds to a flow path axis O of an exit 51e of a mixer 45 where the downstream part of the cooler passage 43 is joined to the downstream part of the bypass passage 44, and an exit 44a of the bypass passage 44 is arranged so that its flow path axis B intersects therewith. In the mixer 45, a mixing plate 52 is stored which has an entrance 52c on the side of the exit 43a of the cooler passage 43 and an exit 52d on the side of the exit 51e of the mixer 45. The mixing plate 52 is arranged so that its axis corresponds to the flow path axis O of the exist 51e of the mixer 45. |
