发明名称 PIPE JOINT
摘要 An object is to provide a pipe joint that enables claw portions 21, which have been biting into the outer circumference of the second pipe 120, to pull out from the outer circumference when locking members 20 are stopped from being pressed by press bolts 30, prevents the locking members 30 from being lost during transportation, and assures the locking members 30 to be sufficiently inclined when an external force in such a direction as to cause the first pipe 110 to be pulled out from the second pipe 120 has been acted on the pipe joint. The pipe joint includes an annular press ring 10 that is mounted around the insertion port 121 of the second pipe 120, the locking members 20 that have claw portions to bite into the outer circumference of the second pipe 120, the press bolts 30 that make the locking members 20 project outward from the inner circumference of the press ring 10, and the elastic members 40 that hold the locking members 20. The press ring 10 includes operational portions 13 having the press portions 11 and the spaces 13d. The elastic members 40 each have elasticity so as to draw the locking member 40 into the space 13d while making the locking member 40 conform to the inclined surface 13f of the space 13d, make the claw portion 21 of the locking member 20 move into and out of the space 13d, and make the locking member 20 to project outward from the space 13d.
