Abstract
An EGR device includes an inlet portion into which EGR gas is introduced, a first outlet portion, a second outlet portion, and a passage portion. The first outlet portion and the second outlet portion each conduct, to the corresponding branch passage portion, the EGR gas that has been introduced through the inlet portion. The passage portion allows gas to flow between the inlet portion and the first outlet portion and between the inlet portion and the second outlet portion. The passage portion includes: a main passage that connects the inlet portion to the first outlet portion and to the second outlet portion; and an expansion chamber that is expanded outward from the main passage. The main passage includes a connecting portion. The connecting portion is connected to the second outlet portion and extends in a first direction. The expansion chamber is expanded outward from the connecting portion.
