<p><P>PROBLEM TO BE SOLVED: To provide a manifold of an internal combustion engine which is reduced in weight while maintaining the necessary support strength and which eliminates the need of an auxiliary member such as a metal stay. <P>SOLUTION: This manifold A of an internal combustion engine comprises a double pipe structure in which an inner pipe 4 is installed, spaced apart from an outer pipe 3, in the outer pipe 3 which is formed by integrating a flange 1 connected to the internal combustion engine side with a connection flange 2 connected to the exhaust system side. An opening 31 allowing the inner pipe 4 to be inserted therethrough is formed in the wall body of the outer pipe 3. A cover part 5 is provided to close the opening 31. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
