いう手順が採られるのが一般的であった。2. Description of the Related Art A conventional water faucet of this type penetrates a wall (a) as shown in FIG. A seal tape is wound around an external thread portion of the faucet (d) on the side of the crank tube (e) to be screwed with the faucet (d), or another seal material is applied and fitted in a watertight manner, and is fitted to the indoor side wall surface. Generally, a procedure of fitting a decorative washer (f) was adopted.

り、締め込み量を調整（緩る締め）すると、締付け不足
を発生し、この部分の水密性を低下させるという課題が
あった。The conventional sealing method described above requires considerable experience and skill in construction. The main reason is that when tightening the crank tube (e) that is screwed into the joint (b), the positional relationship between the joint and the faucet cannot be clearly grasped, and the tightening of the crank tube often occurs. If the amount is excessive or insufficient, return the excessively tightened material to adjust the position each time, or adjust the amount of tightening (loose tightening), insufficient tightening will occur and the water tightness of this part will be reduced There was a problem to make it.

たものである。。[0004] Particularly, in a hot and cold water mixing tap which requires two crank pipes, the connection of the water tap body (d) becomes impossible unless the pipe end positions of both crank pipes are accurately regulated. For this reason, the frequency of adjustment of the tightening amount is increased frequently, and therefore, it is very difficult to maintain watertightness. .

を弾装するという手段を用いた。According to the present invention, in order to achieve the above-mentioned object, an end face of a crank tube fitted to the screw portion abuts on an inner end portion of an inner thread portion of a body portion of a joint penetrating a wall surface. A means was used in which a hollow core having a contact surface was fitted in a watertight and slidable manner, and a spring was elastically mounted between the core and a rear part of the joint body.

Has the effect of maintaining the watertightness. Therefore, unlike the conventional connection structure, it is not necessary to use a sealing material or the like for the screw portion, and a special action that the amount of tightening can be freely adjusted can be obtained.
