<p><P>PROBLEM TO BE SOLVED: To secure the rigidity of a resonator body member without increasing the weight. <P>SOLUTION: In this intake manifold, a resonator part 6 is formed in the space 26 formed between the resonator body member 14 secured to the outer surface of an intake manifold body part 15 and the outer surface of the intake manifold body part 15. The resonator part 6 comprises: a resonator neck part 30 connected to the resonator body member 14 and the outer surface of the intake manifold body part 15 and having an elongated resonator neck part passage 29 formed between a pair of resonator neck part walls 28, 28 opposed to each other; and a resonator volumetric chamber 31 communicating with a collector part 5 through the resonator neck part passage 30. The resonator neck part 30 is positioned on a branch part 3 which is one of a plurality of branch parts 2, 3, 4, and extends along the branch part 3. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
