<P>PROBLEM TO BE SOLVED: To provide a joint capable of suppressing a jet of liquid even if connection between a nose and a body is insufficient. <P>SOLUTION: The body 12 is provided with a recessed insertion part 14 into which the nose 40 is inserted. A resin collet 22 having a protrusion part 22A engaged with a groove part 44 formed in the outer peripheral surface of the nose 40 is disposed in the recessed insertion part 14. A protruding part 17 is formed on the internal wall of a passage part 28 of the body 12, and the protruding part 17 is provided with a movable valve 30. The movable valve 30 comprises a valve element part 32 abutting on the protruding part 17 to close the passage part 28; an annular part 36 having a locking part 36A locked to the protruding part 17; and a plurality of openings 37, 38. When the nose 40 is inserted in the recessed insertion part 14, the movable valve 30 opens the passage part 28, and when the protrusion part 22A comes off the groove part 44, the movable valve 30 is moved in a direction to close the passage 28 by the internal pressure of liquid L. <P>COPYRIGHT: (C)2008,JPO&INPIT |
