<p>PROBLEM TO BE SOLVED: To provide a technique which easily prevents disconnection and ensure seal. SOLUTION: In this structure, opening parts are mutually communicated and connected under such state that the opening parts of a pair of pipe end part P is faced with each other. In this case, a pipe joint main body 1 is installed on the pipe end part P by forming in an externally fittable cylinder shape and a falling stopping metal fitting installation part 2 installed so as to be fixed freely a ring shape falling stopping metal fitting 3 externally fitted to the pipe end part P is installed on the pipe end part P and the falling stopping metal fitting 3 is constituted so as to be installed freely on the falling stopping metal fitting installation part 2 under such state that the pipe joint main body 1 is externally fitted to the pipe end part P. A falling stopping projection part 12 for obstructing the falling off of the pipe joint main body 1 from the pipe end part P by contacting to the falling stopping metal fitting 3 installed on the falling stopping metal fitting installation part 2 under such state that a fitted end part 11a is fitted to the pipe end part P is installed in the fitted end part 11a side externally fitted to the pipe end part P at the pipe joint main body 1 and the space between the falling stopping projection part 12 and the pipe end part P is constituted so as to be able to seal.</p> |
