Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the resonance pressure-charging-type intake manifold itself with the strength, and to make a device compact, by extending a head flange and a throttle body flange in a cylinder arrangement direction through a connecting part, and integrally forming the same. SOLUTION: The first, second, third and fourth independent intake tubes 21, 22, 23, 24 of an intake manifold 20, are connected with a head flange part 14. The head flange part 14 and a throttle body flange part 16 are extended in a cylinder arrangement direction through a connecting part 15 to be integrally formed. A collecting chamber 50 is connected with the throttle body flange part 16 at a left end of a flange plate 13 with which the upstream part of the collecting chamber is overlapped. An EGR valve 60 for controlling the flow rate of the EGR gas, is projected adjacent to and in parallel with the fourth independent intake tube 24, at the side of the head flange part 14 of the connecting part 15. Thereby the installation structure having the structurally high strength and rigidity, of the intake system can be provided, and the device can be made lightened and compact.
