2. Description of the Related Art In a conventional plumbing device, for example, a faucet fitting, a pipe and a pipe joint are fixed to a floor or a wall at a tip of the pipe, and a sealing tape is applied to a threaded surface of the water supply fitting of the faucet fitting. It is common to perform winding and screw fixing. Further, there is a type in which a faucet fitting is connected by a one-touch joint joint as disclosed in Japanese Patent Application Laid-Open No. 8-158427.

[0003]

When a pipe joint is fixed to a floor or a wall surface and a pipe from a water supply source (such as a water stopcock or a branch faucet) to a pipe joint and a water faucet is screwed in and fixed, a pipe is required. Alternatively, seal tape is wrapped around the threaded surface of the water supply fitting, but skill is required in how to wind the seal tape, screwing position, and piping length setting, etc. However, there was a problem that the installation could not be performed and the construction was redone.

To solve the above problem, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent No. 158427, there is a type in which a faucet fitting is connected with a one-touch joint joint. However, only the one-touch joint joint is used, and workability including piping from a water supply source to the one-touch joint joint is included. It does not simplify, improve efficiency, nor improve reliability. Also, considering the retrofitting of water supply devices (faucets, water purifiers, dishwashers, washing machines, etc.), by providing a water (hot water) outlet using a one-touch joint joint, it is convenient for retrofitting water supply devices. However, if one-touch joint joints are provided from the beginning, those who do not need them will spend a lot of money. Further, since the one-touch joint cannot be easily removed, there is a problem that the one-touch joint is exposed when the one-touch joint is not required, and the appearance of the one-touch joint and the adhesion of dirt are attached.

The problem to be solved in the present invention is to simplify the workability from the water supply source to the one-touch joint joint on the mounting surface, to improve the efficiency, and to further improve the reliability, and to connect the water supply device with skill. It can be easily done without.
In addition, the one-touch joint joint itself can be easily attached and detached, so that when the one-touch joint joint becomes necessary, the one-touch joint joint can be easily attached, saving unnecessary expenses for those who do not need the one-touch joint joint. That is not to let. Furthermore,
An object of the present invention is to prevent the one-touch joint joint from being exposed when the one-touch joint joint is unnecessary, to improve the design of the appearance, and to prevent the adhesion of dirt.
