Claims

[Claims for Utility Model Registration] The secondary side mixture passage 5.5' connected to the secondary side intake passage of the carburetor is connected to the primary side mixture passage 4.5' connected to the primary side intake passage of the carburetor. 4', the air-fuel mixture supplied to each air-fuel mixture passage 4, 4/:5.5) is divided at the first branch point P, P', and the air-fuel mixture downstream of the In a tournament-type intake manifold in which the flow is further divided at the second branch points Q and Q', a partition wall 23, 23' is provided on the side closer to the engine body of the first branch points P and P'. A blow-by gas introduction passage 24.24' is formed between the partition wall 23°23' and the manifold outer wall 20.20', and the blow-by gas is introduced at a position near the second branch point Q, Q'. Introduction passage 24. 24' to the mixture passages 4.4' and 5.5'.
Openings 25.25'; 26, 26' are provided to communicate the partition wall 23.23' with the secondary side mixture passage 5, 5.
' and the blow-by gas introduction passage 24. An intake manifold having a blow-by gas introduction passage shaped to equally divide the blow-by gas introduced into the left and right sides.
