環が一体に設けられたことを特徴とする消火栓。[Scope of claim for utility model registration] A long water pipe is formed by connecting a plurality of short water pipes in series, and this water pipe is buried vertically underground with one end protruding above the ground. A water discharge pipe with an open water outlet is attached to one end of the water pipe, and a valve box containing an on-off valve is attached to the other end of the water pipe, and the valve box is connected to the underground water main pipe. The valve stem of the on-off valve passes through the water pipe and water discharge pipe and extends to the ground, so that by operating the on-off valve from the ground, water from the main water supply pipe can be taken in from the water outlet of the water pipe via the water pipe. In the fire hydrant, each of the above water supply short pipes has a cylindrical shape directly above, and a male threaded portion is formed on the outer periphery of the connecting end of the water supply short pipe, and a threaded portion is screwed into this male threaded portion between each water supply short pipe to be connected. A connecting cylindrical body having a female threaded portion formed on the inner periphery is interposed, and by screwing these male threaded portions and female threaded portions, each water supply short pipe is connected to each other in a manner in which the connecting cylindrical body is held between the two. A fire hydrant, characterized in that a support ring held by a stay through which the valve stem is inserted is integrally provided on the inner circumference of the connecting cylinder.
