Abstract:
1. A fixing structure for fixing an intake manifold to an engine, the intake manifold having a manifold body for distributing intake air into cylinders of an engine, and the manifold body including a first end portion on an air inlet side of the intake manifold, a second end portion on an air outlet side of the intake manifold, a surge tank on the side of the first end, and a plurality of resiliently deformable intake pipes arranged in parallel to each other and each having a lower rigidity than that of the surge tank and extending substantially linearly between the surge tank and the second end portion, the fixing structure comprising: a first mounting device capable of fixedly mounting the first end portion of the intake manifold body to the engine by a first fixing force; and a second mounting device capable of fixedly mounting the second end portion of the intake manifold body to the engine by a second fixing force; wherein at least one of the first and second fixing forces applies a bending moment to the intake pipes of the intake manifold body so as to prevent local vibrations of the intake pipes.
