Abstract

[Problem to be Solved] It is to provide an EGR device for an internal combustion engine capable of inhibiting coolant flowing through coolant piping from being affected by heat of an exhaust passage portion to thereby avoid cooling performance of an EGR cooler from deteriorating. [Solution] An EGR device 11 for an engine 1 includes: an EGR cooler 13 provided so as to be adjacent to an exhaust cleaning device 9 on a side where an exhaust side wall 1B is located, constituting a part of an EGR passage portion 12, 13, 26, 15; and a coolant introduction pipe 52 and a coolant discharge pipe 53 both to circulate a coolant into an engine body 2 through the EGR cooler 13 to thereby cool a EGR gas flowing through the EGR cooler 13. The coolant introduction pipe 52 and the coolant discharge pipe 53 are installed on an opposite side of the EGR cooler 13 from the exhaust cleaning device 9.
