<p><P>PROBLEM TO BE SOLVED: To provide an intake manifold having high rigidity and improving pressure-proof strength. <P>SOLUTION: This intake manifold 100 has a lower 3, a resonator plate 4 contacting with the lower 3, and a middle 2 contacting with the resonator plate 4, and constitutes an intake passage, a surge tank space 20 and a resonator space 42. The lower 3 and the resonator plate 4 constitutes the surge tank space 20. The resonator plate 4 constitutes a part of a manifold outer peripheral surface 112. The resonator plate 4 and the lower 3 are joined in the manifold outer peripheral surface 112, and the resonator plate 4 and the middle 2 are joined. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
