摘要： An intake manifold for an internal combustion engine, being variable in an intake length, comprising: a first volume chamber disposed in a downstream side of a throttle valve for controlling an intake air passing through an air-cleaner; first independent intake passages being divided from said first volume chamber for guiding the air within said first volume chamber into each of cylinders; second independent intake passages joining and conducting to each of said first independent intake passages, each of which is provided for said each of cylinders respectively; a second volume chamber conducting to all of said second independent intake passages; and valves being provided in said independent intake passages for conducting/shutting off between said second volume chambers and said first independent intake passage, wherein said first independent intake passage and said first volume chamber are built up with a plural number of synthetic resin molded members, and said second independent intake passage surrounding said valve is formed with a synthetic resin molded member being separate from the synthetic resinmoldedmember forming said first volume chamber and said first independent intake passage.
