<p><P>PROBLEM TO BE SOLVED: To provide a structure of a part mounting portion of a resin pipe with high sealability and enabling the secure and firm mounting of parts. <P>SOLUTION: A resin mounting port 2 is held by a metal restriction ring 3 and a connection port 9 and suppressed in deformation and reinforced. The restriction ring 3 is fitted onto the mounting port 2, engaged with an engagement part 2a, and firmly fixed to the resin pipe 1. The metal restriction ring 3 is firmly connected to the connection port 9 by using a fixing bolt 11. Thus, since the resin pipe 1, the restriction ring 3, and the connection port 9 are firmly fixed integrally with each other for less deformation, and the restriction ring 3 receives a reaction acting on an O-ring 8, the high sealability can be secured by eliminating a clearance between the inner peripheral surface of the mounting port 2 and the connection port 9. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
