SYNTHETIC-RESIN-MADE INTAKE MANIFOLD, AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To ensure the strength and rigidity of each outlet tube, and also to keep the position accuracy of the outlet tube end side. SOLUTION: In a synthetic-resin-made intake manifold W equipped with plural outlet tube parts Wo, branched while the mating center lines of adjoining tubes are forming a given angle in plane view, connecting ribs J for connecting the mating adjoining outlet tube parts are ingerally formed. Also, the connecting ribs J are to be platelike ribs for connecting relatively mating vicinities of the tube end parts between the adjoining outlet tube parts.
