Claims

[Claims for Utility Model Registration] 1. A pipe joint comprising a joint body 2 and a cap nut 4 screwed onto a threaded portion 3 of the joint body 2, wherein the cap nut 4 has a circular outer circumferential surface 14. The nut body 8 is formed from a nut body 8 which is screwed into the threaded portion 3 of the joint body 2 so as to be able to move forward and backward, and a circular ring body 9 which is fitted onto the nut body 8. A protrusion 15 for preventing rotation is provided on the circular outer circumferential surface 14, and a fitting groove 17 into which the protrusion 15 fits is provided on the circular inner circumferential surface 16 of the ring body 9. A pipe joint characterized in that a plurality of thin cutting portions 19 are arranged at predetermined pitches along the circumferential direction to be cut with a tightening torque of . 2. Three or more of the anti-rotation protrusions 15 are arranged along the circumferential direction at equal intervals around the circumference, and the fitting grooves 17 that fit into the anti-rotation protrusions 15 are arranged along the circumferential direction. The pipe joint according to claim 1, wherein three or more pipe joints are arranged at equal intervals.
