Egr gas distributor

An EGR gas distributor configured to distribute EGR gas to each of a plurality of branch pipes configuring an intake manifold,

• the EGR gas distributor comprising:
• a gas chamber in which the EGR gas is collected;
• a gas inflow passage configured to introduce the EGR gas into the gas chamber on an upstream side of the gas chamber;
• a plurality of gas outflow passages configured to discharge the EGR gas residing in the gas chamber to a plurality of the branch pipes on a downstream side of the gas chamber;
• and
• an inner wall on the downstream side of the gas chamber being divided into a plurality of downstream-side divided walls each of which corresponds to each of a plurality of the gas outflow passages and each of which is curved or slanted to be of protrusion-like shape protruding toward an inlet of the corresponding gas outflow passage, and a downstream-side dividing ridge as a boundary provided between the adjacent downstream-side divided walls, wherein
• an inner wall on the upstream side of the gas chamber is placed to face the inner wall on the downstream side and is provided with at least one upstream-side protruding portion protruding toward the downstream-side divided wall in each area corresponding to the respective downstream-side divided walls.
