Claims

[Claims for Utility Model Registration] (1) A ring body having a tapered surface on the outside, and a plurality of slits extending in the direction of the large diameter end at multiple locations in the circumferential direction of the small diameter end due to the taper. A retaining fitting for connecting a water supply pipe, which has a flange formed at the end on the large diameter side. (2) In a connection structure for water supply pipes with different pipe diameters, the end of a small diameter pipe is inserted into the end of a large diameter pipe with an external thread, and a nut with an inner flange is inserted outside the small diameter pipe. is screwed onto the threaded portion of the large-diameter pipe end, and a packing ring that contacts the large-diameter pipe end is disposed inside the nut, and the ring body has a tapered surface on the outside. The retaining metal fitting has slits extending toward the large diameter end formed at multiple locations in the circumferential direction of the small diameter end due to the taper, and a flange formed at the large diameter end. It is arranged so as to be in contact with the packing ring, and when the nut is tightened, the packing ring is pressed against the end of the large diameter pipe via the flange of the retaining metal fitting, and the edge of the inner flange of the nut is brought into contact with the locking metal fitting. A water supply piping connection structure in which the ring body contacts the tapered surface of the pipe, reduces its diameter, and bites into the outer surface of the small diameter pipe.
