    • PROBLEM TO BE SOLVED: To increase a degree of freedom of volume setting of a resonator and to facilitate the attachment by mounting a third split segment on the outer side of a second split segment and making it easy to join the third split segment.
      SOLUTION: An suction manifold of an internal combustion engine includes: an independent suction passage connecting a downstream-side opening end portion to suction ports of the internal combustion engine; a first split segment having a first recessed portion adjoining the opening part on an upstream side opening end of the independent suction passage and recessed at the side of the independent suction passage and a first joint portion formed so as to surround the upstream side opening end of the independent suction passage and the outer periphery of the first recessed portion; and the second split segment having a second joint portion contacted on the first joint portion and a second recessed portion opening an end on the inner periphery of the second joint portion and recessed on the reverse side of the independent suction passage. Suction air is introduced from the first recessed portion to the independent suction passage through the second recessed portion by joining the first split segment and the second split segment. A communication hole communicating with the outside is formed in the second split segment, the third split segment is mounted from outward of the communication hole and the resonator including the second split segment and the third split segment on the outer wall is formed.
