<P>PROBLEM TO BE SOLVED: To prevent burr occurring on the inner peripheral side of an annular projection from mixing into a common rail in a sealing structure of inserting the annular projection into a receiving surface. <P>SOLUTION: The annular projection 5c of a pressure sensor 5 (mating member) is inserted into the receiving surface 14 formed at the peripheral edge of an opening of a rail hole 13 (fuel flow channel) in the common rail 1, and the inserting part seals it. Even when a burr 9 occurring inside the annular projection 5c is peeled from the receiving surface 14 due to the insertion of the annular projection 5c into the receiving surface 14, the burr 9 does not come into the rail hole 13 because a ring-like regulating member 17 (regulating means) is disposed between the annular projection 5c and the rail hole 13. <P>COPYRIGHT: (C)2003,JPO |
