ABSTRACT:
Conventional intake passage apparatuses used in internal combustion engines, which have closed cross sections perpendicular to air current direction, have had to be manufactured by casting using cores. An intake passage apparatus according to the present invention comprises two divisions having their joint surfaces extending in the air current direction and bonded to each other by means of an adhesive agent. Also, the divisions are fixed by mechanical clamping. Thus, no closed cross sections are present in the divisions, so that the molding work is easier.
