    Abstract: A surge tank structure in an intake manifold has a surge tank to which a plurality of branch tubes are joined at one end. The branch tubes are joined at the other end to a cylinder head mounting flange, and one end of each branch tube in the surge tank is enlarged to have a horn-like shape. The surge tank comprises a main body and a top plate. The main body has through holes provided therein for accepting the branch tubes and has its top side opened. The top plate is joined in a plane to the top of the main body. The main body has a bottom which has engagement recesses formed by raised portions, so that each engagement recess has a horn-like surface that conforms to the horn-like shape of one end of each branch tube.
