To provide a synthetic resin intake manifold for integrating the housing of a fuel spray guide and an injector holding function with an independent intake pipe, in an intake manifold provided with an injector common for plural cylinders of a multidirectional fuel injection type.
This intake manifold 100 is a synthetic resin mold body formed with the collective body of the independent intake pipe 103 diveded into upper and lower bodies. The upper divided mold body 110 is formed by integrally molding the one-side division wall 111 and a collector part 102 of the independent intake pipe, a throttle body mounting flange 101, and a cylinder head mounting flange 104. The lower divided mold body 120 is formed by integrally molding the other-side division wall 121 of the independent intake pipe, an injector housing part 106, and a fuel spray guide 105. The intake manifold is composed by welding the divided mold bodies.
