<p><P>PROBLEM TO BE SOLVED: To provide a pipe joint capable of easily moving a sleeve 9 in the axial direction without receiving the self-weight and bending load of a pipe P, improved in its workability, and surely stably obtaining the predetermined stopping function, in the pipe joint comprising the stopping mechanism 12 formed by mounting the sleeve 9 and a ball 11 held in the sleeve 9 between a joint main body 1 and the pipe P, and preventing the slip-off of the pipe P by pressing the stopping ball 11 to an outer face of the pipe P through a taper face 3a formed on an inner face of the joint body 1 in a state of enlarged at a depth side. <P>SOLUTION: Projections 20 larger than an inner diameter of the sleeve 9 and smaller than an outer diameter of the pipe P are formed on opening end part of the joint body 1 at specific intervals in the circumferential direction, and cuts 21 of a predetermined depth are formed from one end of the sleeve 9 to fit the projections 20 of the joint body 1, so that the self-weight and bending load of the pipe P are received by the projections 20 of the joint body 1. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
