HIGH-PRESSURE PIPE FITTING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a high-pressure pipe fitting structure of an inexpensive and simple configuration without any interference with an engine or the like by preventing an inlet connector 5 from being loosened when detaching a high-pressure pipe such as a high-pressure fuel feed pipe, any oil leakage from occurring, and the structure from being changed in appearance.

SOLUTION: A connection tip part 16 of the inlet connector 5 has a shape to be relatively and plastically deformed to a connection bottom part 15 of a housing body 3 (a pipe fitting part). A high-pressure pipe fitting structure comprises a locking part 31 formed on the connection bottom part 15 of a fitting hole part 13 formed in the pipe fitting part 3 and a biting part 32 formed on the connection tip part 16 of the inlet connector 5 facing the locking part 31, and the locking part 31 and the biting part 32 are integrated with each other by screwing the inlet connector 5 in the fitting hole part 13.
