Claims

[Scope of utility model registration request]

An intake system for an internal combustion engine including an intake system having an intake manifold connected to an engine body such that a downstream opening communicates with an intake port, the outside of which is a member directly fixed to the inlet of the intake port. The peripheral edge and the outer peripheral edge of the downstream opening are connected substantially only through the elastic member, and the center of gravity of the intake system is determined directly above the elastic member, and the center of gravity of the intake system is located directly above the center of gravity. An intake device for an internal combustion engine, characterized in that the intake device is supported by an engine body by a support member provided in the engine body.
