。 A radial step 12a is formed on the outer periphery of the end of one first pipe 11, and the radial step 12a is
The front end portion 31 of the locking member 30 is immovably engaged with the front end side of the first pipe, and the seal member 1 is attached to the outer periphery of the first pipe on the pipe end side from the radial step portion 12a.
3 is attached, and a pressing protrusion 34 formed to be elastically displaceable in the radial direction of the locking member 30 is engaged with the outer periphery of the end of the other second pipe 15 that surrounds the outer periphery of the seal member 13 so as to press against the outer periphery of the seal member 13. A locking hole 17 for locking the first pipe 1 is formed in the pressing protrusion 34.
a locking groove 35 in which the edge of the locking hole 17 locks so as to restrict the elastic displacement of the pressing protrusion 34 when the second pipe 1 moves in a direction away from the second pipe 15;
A pipe joint structure characterized by forming.
