。[Claim for Utility Model Registration] Supercharging of an internal combustion engine in which a butterfly valve that opens and closes the bypass passage in response to boost pressure from the supercharger is installed in a bypass passage that detours around a supercharger. The pressure control device for an internal combustion engine is characterized in that a partition wall is provided in the bypass passage and extends along the longitudinal direction of the bypass passage from the vicinity of the rotation axis of the butterfly valve toward the upstream side of the bypass air. Supply pressure control device.
