Abstract
In an EGR device in which an EGR passage is merged with an intake passage communicating with a compressor housing of a supercharger, the EGR passage is extended to the inner side of the intake passage with respect to a junction between the EGR passage and the intake passage, and the position of a terminal end of an extended passage section in an air flow direction matches the position of a terminal end of the intake passage, the extended passage section being the EGR passage extended. The merged passage section where the EGR passage is merged with the intake passage is a joint pipe that connects an intake tube and the compressor housing.
