Title: Resin intake manifold for multicylinder engine

Abstract: An intake manifold is assembled from a near manifold component which is positioned near an engine, a far manifold component which is positioned far from the engine and a middle manifold component which is positioned between the near and far manifold components. The near manifold component includes first path-forming parts forming the lower parts of the intake paths. The middle manifold component includes second path-forming parts which are joined on and vibration-welded to the first path-forming parts. The middle manifold component further includes third path-forming parts which extend in the vertical direction in a curve. Further, the far manifold component includes fourth path-forming parts which are vibration-welded to the third path-forming parts.
