The partition plate (6) has an upstream edge (6c) which includes a major straight portion (6c-1) and two projected end portions (6c-2,6c-3) which are provided on both ends of the major straight portion respectively, and the major straight portion (6c-1) is positioned inside relative to the side wall surface (5) and the two projected end portions (6c-2,6c-3) have upstream edges which are embedded in the inner wall of the intake port (3) and machined to be flush with the side wall surface (5).",
