PROBLEM TO BE SOLVED: To provide a pipe fitting structure which achieves the sealability, a removal prevention function, and flexibility even if an external force involving a large scale earthquake or ground fluctuation acts thereon.SOLUTION: A pipe fitting structure includes: a pipe joint 5 in which a spigot part 2a of one fluid pipe 2 is inserted into a socket part 3c of the other fluid pipe 3 to be connected thereto in a sealing manner; and a housing 11 enclosing the pipe joint 5 in a sealing manner; and removal restriction parts 12, 3g which allow the spigot part 2a and the socket part 3c to move relative to each other in a pipe axis direction and restrict removal of the spigot part 2a and the socket part 3c from the housing 11.SELECTED DRAWING: Figure 1 |
