Claims

[Scope of utility model registration request]

A riser part provided in the intake manifold body and communicating with the primary side passage and the secondary side passage of the two-barrel carburetor, and a branch passage branched from the riser part, and the riser part is connected to the branch by a partition wall. In an intake manifold for an internal combustion engine, the intake manifold for an internal combustion engine forms a primary riser section and a secondary riser section that are divided up to a vicinity of a passage entrance and allow the primary side passage and the secondary side passage to communicate independently with the branch passage. An intake manifold for an internal combustion engine, characterized in that a communication part is formed at a lowermost portion of the manifold to communicate the primary riser part and the secondary riser part.
