Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pipe fitting capable of contracting diameter peripherally easily without being ruptured. SOLUTION: A seal ring 4 is provided with a rubber ring 40 being peripherally annularly continuous and an annular coil spring 41 stored in the rubber ring 40 and holding a cross section shape of the rubber ring 40. In the rubber ring 40, a storage hole 43 storing the coil spring 40 and having substantially circular cross section and a circumferential channel opening the storage hole 43 on an outer peripheral side of a pipe and allowing insertion of the coil spring 41 into the storage hole 43 are formed. Cross section of the rubber ring 40 is substantially formed into a C shape. Since the cross section of the rubber ring 40 is substantially formed into the C shape in this way, diameter of the rubber ring 40 can be easily contracted peripherally. COPYRIGHT: (C)2007,JPO&INPIT
