<p><P>PROBLEM TO BE SOLVED: To provide a connection structure of a surge tank, which has a sufficient strength, even with application of a big stress without causing air leakage, and further provide a surge tank, and an intake manifold. <P>SOLUTION: In the connection structure of the surge tank, end faces of at least two pieces of split-molded surge-tank pieces 1, 2 are connected by vibration-welding. In the one surge-tank piece 1, a projection 12 for connection is provided peripherally on the end face. The other surge-tank piece 2 is provided with two grooves 23, 24 at the end faces, and a peripheral projection-receiving part 22 for connection between the two grooves 23, 24. The projection 12 for connection and the projection-receiving part 22 for connection are provided both off the central position of the end face to the inside. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
