ツトとの接続構造。[Scope of Claim for Utility Model Registration] 1. A threaded portion having a parallel internal thread formed on its inner surface is provided with a packing receiving portion whose diameter expands outward in a tapered shape, and the other side of the threaded portion has a diameter larger than that of the threaded portion. The adjustment socket is provided with a bulge portion having a large diameter, and a connection port for the sprinkler is provided in a cylindrical portion extending from the bulge portion, and an unwinding part for the sprinkler having a parallel male thread formed at the end. The connection structure with the pipe is such that the parallel female thread of the threaded portion of the adjustment socket is screwed into the parallel male thread of the unwinding pipe, and a ring-shaped rubber packing is screwed onto the parallel male thread. A lock nut which is tightened by a nut and is in close contact with the packing receiving part and the tightening nut, the inner circumferential part of the rubber packing tightly meshes with the parallel male thread, and the tightening nut is screwed into the parallel male thread. A connection structure between a sprinkler unwinding pipe and an adjustment socket, characterized in that it is prevented from loosening by. 2. In the return pipe connection structure of claim 1, the rubber packing is compressed so that the packing body, which has a bullet-shaped cross-sectional shape in an uncompressed state, is pinched by the taper receiving portion and the tightening nut and comes into surface contact with them. A connection structure between a sprinkler unwinding pipe and an adjustment socket which is deformed and in which a parallel female thread formed on the inner circumference of a packing body engages with a parallel male thread of the unwinding pipe.
