摘要：PROBLEM TO BE SOLVED: To provide an EGR device capable of reducing thespace required for mounting. An EGR device includes a case, a catalyst, and an EGR pipe.Exhaust gas from an internal combustion engine flows into the case. The catalyst ishoused inside the case and has a flow path connecting the first space on the upstream
side and the second space on the downstream side of the catalyst in the flow direction ofthe exhaust gas. At least a part of the portion covering the side surface of the catalyst inthe case is a double tube portion having an inner tube and an outer tube. The outer pipeof the double pipe portion is provided with an EGR outlet to which the EGR pipe isconnected. The double pipe portion includes a closed portion that closes the gapbetween the inner pipe and the outer pipe so as to suppress the inflow of exhaust gasfrom the first space to the EGR outlet.
