<P>PROBLEM TO BE SOLVED: To prevent a cap from being loosened when a pipe joint is rotated with respect to a holder for installing the pipe joint at a predetermined position. <P>SOLUTION: The holding structure of a pipe joint includes a pipe joint 10, a holder 12 and a spacer 14. The pipe joint 10 includes a tubular joint substrate 18 configured to connect piping thereto and a cap 22 which is screwed to the joint substrate 18 and fixes the piping to the joint substrate 18. The holder 12 is configured to hold the outer circumference of the cap 22 and installs the pipe joint 10 at a predetermined position. The spacer 14 is disposed between the holder 12 and the cap 22 and configured to be relatively rotatable with respect to the cap 22. When the pipe joint 10 is rotated with respect to the holder 12, rotations of the cap 22 are not restricted by the holder 12, thereby preventing relative rotations from occurring between the cap 22 and the joint substrate 18. <P>COPYRIGHT: (C)2013,JPO&INPIT |
