INTAKE MANIFOLD

PROBLEM TO BE SOLVED: To firmly integrate respective components while constituting portions not requiring heat resistance so much by an inexpensive resin material with low heat resistance when resinifying an intake manifold. SOLUTION: A surge tank part has a suction air intake port 11, an outlet cylinder part 22 communicated with the inside of the surge tank part, and a mounting part 15 mounted to an engine. A connection cylinder part 35 connected to a suction passage of the engine is provided in the mounting part 15. A suction pipe part 4 comprises a resin material having lower heat resistance than that of a resin material constituting the surge tank part. An upstream side connection part 41 connected to the outlet cylinder part 22 is formed on the upstream side of the suction pipe part 4, and a downstream side connection part 42 connected to the connection cylinder part 35 is formed on the downstream side of the suction pipe part 4. The outlet cylinder part 22 and the upstream connection part 41 are connected with each other with one press fitted to the other, and the connection cylinder part 35 and the downstream side cylinder part 42 are connected to each other with one press fitted to the other.
