<P>PROBLEM TO BE SOLVED: To surely prevent looseness by external force such as vibration of a fixing ring for fixing a clamp for connecting mutual joints. <P>SOLUTION: This connecting joint structure 1 substantially includes the clamp 3 communicably fitted by sandwiching a first joint 10 and a second joint 20, the fixing ring 4 arranged in the first joint 10, slidably arranged in the pipe axis O direction and pressing down the clamp 3 by being pushed in the clamp 3 side in the pipe axis O direction, and a projecting member 5 projected on an outer peripheral surface of the first joint 10 for arranging the fixing ring 4. The connecting joint structure 1 is provided for connecting the first joint 10 and the second joint 20 by pressing down the clamp 3 by locking the fixing ring 4 between the projecting member 5 and the clamp 3 in a state of elastically deforming any one of the fixing ring 4 and the projecting member 5 by elastically deformably forming the any one of them. <P>COPYRIGHT: (C)2013,JPO&INPIT |
