Abstract
An intake manifold to be mounted to a traverse engine includes pieces made of resin and welded to each other. The pieces are constructed with a first piece having a connector to be connected to the engine, and a second piece. The second piece has an upper positioning part overlapping with the first piece except for the connector having a linear-shaped outlet passage. The upper positioning part is welded to the first piece so as to define an upstream side passage of the outlet passage. The first piece has a cover, which covers the upper positioning part defining a downstream end of the upstream side passage.
