<P>PROBLEM TO BE SOLVED: To provide an easy release joint providing smooth insertion and connection without damaging a component such as a seal member in insertion of a joining pipe, enabling smooth passage of a guide ring through the seal member, stably securing a squeeze of the seal member for a long period of time by suppressing stress relaxation of the pipe due to a fluid pressure, and exercising stable performance even in assemblability and working efficiency. <P>SOLUTION: A lock ring 17 and a cylindrical indicator 20 are housed in a joint body 10. The cylindrical indicator 20 is formed integrally with an outer cylinder part 22 having an insertion gap part 24 for inserting the joining pipe 50 from a deep part 21a of an inner cylinder part 21. An inner circumferential seal member 29 is attached to an attachment groove 21b, and an outer circumferential seal member 30 is attached to an attachment part 23. The guide ring 40 is inserted in the insertion gap part 24 to press the outer circumferential seal member 30 against an outer circumferential face 40a, and to press an inner circumferential face 40b against the inner circumferential seal member 29. <P>COPYRIGHT: (C)2007,JPO&INPIT |
