PROBLEM TO BE SOLVED: To provide an exhaust gas recirculation device for an engine, for suppressing the generation of condensed water from exhaust recirculation gas.SOLUTION: In one embodiment of this invention, the EGR device includes an intake passage for introducing intake air into the engine, an exhaust passage through which exhaust gas is exhausted from the engine, and an EGR passage connecting the intake passage and the exhaust passage for recirculating EGR gas as part of the exhaust gas into the intake passage. At least in an area, out of the intake passage and the exhaust passage, where the intake air and the EGR gas are joined, a resin layer 50 is provided which is formed of a resin. Inside the resin layer 50, a metal layer 52 is formed having high temperature rising characteristics to enable temperature rise in a shorter time than the resin layer 50.SELECTED DRAWING: Figure 2 |
