置。[Scope of Claim for Utility Model Registration] Each individual intake passage of a cast intake manifold is connected to each cylinder of the engine, and the intake manifold is integrally provided with an enlarged EGR passage formed by a core, The enlarged ECR passage extends in the arrangement direction of the independent intake passages and is partitioned from the independent intake passages by a partition, and the enlarged ECGR passage and the independent intake passage are connected to a communication hole bored in the partition. In the exhaust gas recirculation control device for an engine, the core support hole that supports the core when casting the intake manifold is formed between the adjacent independent intake passages on the outer wall facing the partition wall. An exhaust gas recirculation control device for an engine, characterized in that the communication hole is located at the center, and the communication hole is provided so that its center line passes through the core support hole.
