<p>PURPOSE:To correspond to the case of movably fluctuating a connecting direction by connecting a pair of coupling members, having respectively a fluid flow path in the inside further with spherical internal surface parts, by a connecting member, having an intermediate flow path and spherical external surface parts suited for the spherical internal surface party, through engagement between the spherical internal/external surface parts. CONSTITUTION:A pipe coupling, connected to a connected objective part by plug-in one-touch connection, is constituted of the first/second coupling members 11, 31 and a connecting member 51 for connecting these members 11, 31. In the respective insides of the first/second coupling members 11, 31, the first flow path 13, first spherical internal surface part 14, second flow path 33 and the second spherical internal surface part 34 are formed. An intermediate flow path 57 and spherical external surface parts 54, 56 corresponding to the first/second spherical internal surface parts 14, 34 are formed in the connecting member 51. The spherical external surface parts 54, 56 of the connecting member 51 are engaged with the spherical internal surface parts 14, 34 of both the coupling members 11, 31, to perform connection thereof. Thus, both the coupling members 11, 13 are made relatively flexible through the spherical surface parts.</p> |
