<P>PROBLEM TO BE SOLVED: To provide a pipe joint which facilitates the drawing-out work of pipes by releasing the lock by a lock ring even if failing to secure wide space therearound. <P>SOLUTION: In a pipe joint 10 equipped with an outer cylinder part 26, a lock ring 40 for making a pipe 20 locked into a coming-off prevention state by making a claw 44 protruded obliquely bite into the outer surface of the pipe 20, an unlocking part 64 for unlocking the lock by enlarging the claw 44 of the lock ring 40 by forward movement, an unlocking operation part 68 for adding operation force for unlocking, the unlocking operation part 68 is made to be rotatable around the axial center of the outer cylinder part 26 and slidable in the rotating direction with respect to the lock releasing part 64 while the unlocking part 64 and the unlocking operation part 68 are constituted as a separated body. The pipe joint is provided with a cam part 76 for converting the rotating motion of the unlocking operation part 68 into forward movement in the axial direction by the unlocking part 64. <P>COPYRIGHT: (C)2007,JPO&INPIT |
