いられるようになってきた。BACKGROUND OF THE INVENTION When supplying tap water to a washbasin, a cooktop, a flush toilet, etc., it has been common practice to use a copper pipe or a stainless steel bellows pipe and the like with cap nuts attached at both ends. It is used. However, if the installation location is small, or the installation length or position is changed during the construction process, it is difficult to fix it due to the lack of flexibility of the tube itself, and it takes time to install it. Therefore, an EPDM rubber tube is used for the inner surface layer, and the outer circumference of the rubber tube is reinforced by braiding with a stainless steel wire.
A hose type flexible joint in which a joint fitting is caulked and fastened to a space has come to be used.

問題があった。Such a hose-type flexible joint can easily be mounted in a narrow place, which is a drawback of the conventional joint, and a change in mounting position, but on the other hand, it is possible. The flexible hose has a versatile and highly versatile shape with cap nuts on both ends.When the cap nut is screwed into the other side and tightened, the hose is attached with the hose still twisted. Often happens. If the hose-type flexible joint is attached while being twisted in this way, not only does it look unattractive, but it also reduces the sealing properties of the joint between the joint fitting and the hose, and repeatedly presses the hose. -There was a problem that the screw fastening portion such as the cap nut was loosened due to the twisting force of returning the hose, causing water leakage and shortening the life of the hose.

These problems have been addressed by attaching connecting parts with mechanisms. However, these parts are relatively expensive, and there is a big problem in terms of versatility of the parts.

It is preferable to have a structure in which a packing material is formed in the inner step portion. Of course, the outer peripheral joint fitting may be a joint fitting provided with a male screw in some cases.

The longitudinal direction is regulated between this step portion and the sleeve fastened to the hose to enable circumferential rotation. Further, an O-ring groove is formed on the opposing engaging surfaces of the nipple and the outer peripheral metal fitting, and the O-ring groove is formed here.
The ring is fitted and sealed, and a cap nut for fitting is provided on the outer periphery of the outer peripheral fitting as a part of the outer peripheral joint fitting having a threaded portion to be screwed to the mating connecting end. It has a structure in which it is sealed with the packing attached to the other end. Further, according to the present invention, it goes without saying that the outer peripheral fitting and the cap nut may be integrated to form the outer peripheral fitting if there is no problem in handling.
