Abstract
An EGR gas distributor for distributing EGR gas to each of branch pipes of an intake manifold includes a gas chamber, a gas inflow passage, and a plurality of gas distribution passages. The inner wall of the gas chamber on a downstream side is divided into a plurality of downstream divided walls corresponding to the gas distribution passages. On the boundary between adjacent two of the downstream divided walls, a downstream ridge is provided in a perpendicular direction to the arrangement direction of the gas distribution passages. The downstream ridges are arranged side by side in number corresponding to the number of gas distribution passages. The downstream ridges each include a side surface in the arrangement direction. The downstream ridges are different in at least one of height and inclination angle of the side surface according to the positions of the downstream ridges.
