A resin air intake system provided with an intake control valve which permits simplifying the mold structure and maintaining axis center precision. In an air intake manifold, air intake passages are fabricated to be opened and provided with an intake control valve supported by a shaft having an axis in a direction perpendicular to the axes of the openings. The air intake manifold is molded from a resin as an air intake manifold proper and an air intake manifold cluster which have split faces, the split face of the air intake manifold proper provided with grooves in a direction perpendicular to the axes of the openings. Bearings which slidably support the shaft are mounted in the grooves and a projection which projects from the split face of the air intake manifold cluster is brought into contact with the bearings.
An air intake system comprising an air intake manifold (20) having inlet (23) and outlet (15) passages and a control valve (31) supported by a shaft (30), characterized in that said manifold (20) has a split face comprised of at least a first and a second molded part, said first part being provided with a groove (18) therein for receiving a bearing (32) for slidably supporting said shaft (30) and for receiving a projection (43) on said second part for retaining said bearing (32) and aligning said first and second parts.
