ABSTRACT:
A resin intake manifold is provided with an integrally formed base member. The base member has a U-shaped curved distribution passage lower surface wall portion, an engine mounting flange portion formed in one end of the distribution passage lower surface wall portion, and a surge tank peripheral wall portion formed in another end and a lower surface side of the distribution passage lower surface wall portion. A resonator peripheral wall portion is integrally formed in a dead space in a lower surface side of the distribution passage lower surface wall portion and between the surge tank peripheral wall portion and the engine mounting flange portion. In accordance with the structure in which the wall itself constituting the resonator is formed by the structure member, it is possible to structure the resonator without enlarging a size of the intake manifold and without lowering the strength.
