Claims

[Claims for Utility Model Registration] 1. A retainer 2 that can be externally fitted onto the pipe end 1a in a state where it is not removed, and the retainer 2 is inserted from one end side while being externally fitted onto the pipe end 1a. Insertion hole 3 for
a, and an insertion regulating surface 3b formed on the insertion side end of the tube 1 and facing in the tube axis direction.
and a nut member 4 that presses and inserts the retainer 2 by screwing into the joint body 3.
and an insertion hole 3a on the outer peripheral surface of the stopper 2 as the stopper 2 is inserted from one end side into the insertion hole 3a of the joint body 3.
A rotation-preventing protrusion 6 that bites into the peripheral wall surface of the joint body 3 to prevent rotation of the retainer 2 about the tube axis with respect to the joint body 3, and comes into contact with the end surface of the joint body 3 around the insertion hole. A stopper 7 for restricting the insertion of the retainer 2 into the insertion hole 3a from the other end side to an insertion amount that prevents the protrusion 6 from being inserted into the insertion hole 3a is provided in series with the protrusion. A pipe joint in which the strip 6 is formed in such a shape that the protrusion height from the outer circumferential surface of the retainer 2 gradually decreases toward one end. 2. The pipe joint according to claim 1, wherein the stopper 7 includes the other end of the protrusion 6. 3 The insertion amount regulated by the stopper 7 is
Removal stopper 2 inserted into the insertion hole 3a from the other end side
3. The pipe joint according to claim 1, wherein the amount is such that one end of the retainer 2 protrudes from the joint body 3 so as to prevent the nut member 4 pressing the nut member 4 from being screwed into the joint body 3.
