Abstract
A resin intake manifold includes a chamber section having an intake air inlet pipe , and a plurality of outlet pipes which connect cylinders of an internal combustion engine to the chamber section . The resin intake manifold is made by coupling half-parts A and B of divided halves of the chamber section and the outlet pipes divided along a direction of the pipe axis. The outlet pipes are connected to the chamber section so that the external wall of the outlet pipes on the side of an end is integral with the external wall of the chamber section . Further, the outlet pipes extend from the chamber section along a direction of the pipe axis, and are curved to extend in a direction away from the chamber section with a curve angle in a range of not smaller than 90° and not larger than 180°, and continuously extend away from the chamber section
