の管継手。[Claims for Utility Model Registration] 1. First annular grooves for mounting annular elastic bodies are formed on the inner circumferential surface of both open ends of a cylindrical joint body, and the joint is located inwardly from these first annular grooves. A second annular groove into which a split ring for pipe tightening is fitted is formed on the inner peripheral surface of the main body, and a joint is formed on the inner peripheral surface of the jetty provided between the first annular groove and the second annular groove. A tapered surface is formed that becomes larger in diameter as it goes inward from the open end of the main body, and a tapered surface is formed on the outer peripheral surface of the split ring that is in contact with the tapered surface. A pipe joint characterized in that when the intersection of the surfaces is located on the central axis of the joint body or on a line parallel to the central axis, the intersection of the other tapered surface deviates from this line. 2 The relationship between the angle θ 1 of the tapered surface formed on the split ring and the angle θ 2 of the tapered surface formed on the jetty is θ 1
≧ θ2 The pipe joint according to claim 1 of the utility model registration claim.
