PROBLEM TO BE SOLVED: To provide a passage port for a cooling system that can make passage resistance small while reducing a machining cost. SOLUTION: A channel port 11 is provided with a connector part 13 and a pipe part 14 mounted to the cooling system. An elbow part 15 at which a passage bends, is formed inside the connector part 13. The passage in the channel port 11 is continuous in the elbow part 15 and pipe part 14. Both end parts of the connector part 13 are one stage lower and made stop parts 16 mountable to the cooling system. A bolt through-hole 17 is formed at the center part of each stop part 16. The channel port 11 is formed in block shape provided with the connector part 13 with the stop parts 16, and the pipe parts 14. The channel port 11 is formed by high precision aluminum die casting, and the connector part 13 and pipe part 14 are integrally formed. COPYRIGHT: (C)2003,JPO
