摘要：
In an intake structure of an internal combustion engine (10), on an intake upstream side from a valve seat (32) of an intake port (22), a convex portion (36) is provided which protrudes to an inside of the intake port (22) in a place near an outer circumferential portion of a cylinder chamber (12) when viewed from an upper side of the cylinder chamber (12). The convex portion (36) includes an upstream guide surface (3602) extending from an apex (3610) of the convex portion (36) to the intake upstream side, and a downstream guide surface (3604) extending from the apex (3610) to an intake downstream side and including a curved surface recessed inside the convex portion (36) at a middle portion thereof.
