Therefore, according to this embodiment, the following effects can be obtained.
(1) In the mounting structure of the hot and cold water mixing faucet 15 in this embodiment, the water supply side leg 21 and the hot water supply side leg 22 of the hot and cold water mixing faucet 15 are connected to the adapters 16 and 18 by connection nuts 26. Further, adjustment gaps 27 and 28 for adjusting the positions of the adapters 16 and 18 in the radial direction are formed between the water supply side leg 21 and the hot water supply side leg 22 and the connection nut 26.

このため、アダプター16、18の位置がずれても、そのずれを調節用隙間27、28で吸収することができる。従って、湯水混合水栓15の給水側脚部21及び給湯側脚部22を各々給水管13及び給湯管14に簡単に接続することができる。   For this reason, even if the positions of the adapters 16 and 18 are deviated, the deviation can be absorbed by the adjustment gaps 27 and 28. Therefore, the water supply side leg 21 and the hot water supply side leg 22 of the hot and cold water mixing faucet 15 can be easily connected to the water supply pipe 13 and the hot water supply pipe 14, respectively.

よって、本実施形態における湯水混合水栓15の取付構造によれば、別部品を使用することなく、給水管13及び給湯管14に対する湯水混合水栓15の接続作業を容易かつ迅速に行うことができる。   Therefore, according to the mounting structure of the hot and cold water mixing faucet 15 in this embodiment, the operation of connecting the hot and cold water mixing faucet 15 to the water supply pipe 13 and the hot water supply pipe 14 can be performed easily and quickly without using separate parts. it can.

(2)前記給水側脚部21又は給湯側脚部22と接続ナット26との間の調節用隙間27、28は、管接続用アダプター16と貫通孔12との間の隙間29よりも大きくなるように設定されていることが好ましい。このようにすれば、管接続用アダプター16を壁11に固定する位置がずれても、そのずれは調節用隙間27、28のクリアランス内である。従って、調節用隙間27、28により、管接続用アダプター16の位置ずれに対して有効に対応することができる。   (2) The adjustment gaps 27 and 28 between the water supply side leg 21 or the hot water supply side leg 22 and the connection nut 26 are larger than the gap 29 between the pipe connection adapter 16 and the through hole 12. It is preferable that they are set as follows. In this way, even if the position for fixing the pipe connection adapter 16 to the wall 11 is deviated, the deviation is within the clearance of the adjustment gaps 27 and 28. Therefore, the adjustment gaps 27 and 28 can effectively cope with the displacement of the pipe connection adapter 16.

(3)前記給水側脚部21及び給湯側脚部22は給水側本体211及び給湯側本体221に螺合されるねじ部材23を有するとともに、接続ナット26はねじ部材23と連結用アダプター18とを接続するように構成されている。このため、給水側脚部21と給水管13との接続構成及び給湯側脚部22と給湯管14との接続構成を簡易にして、所望の調節用隙間27、28を形成することができる。   (3) The water supply side leg 21 and the hot water supply side leg 22 have a screw member 23 screwed to the water supply side main body 211 and the hot water supply side main body 221, and the connection nut 26 includes the screw member 23, the connecting adapter 18, and the like. Is configured to connect. For this reason, the connection structure of the water supply side leg part 21 and the water supply pipe | tube 13 and the connection structure of the hot water supply side leg part 22 and the hot water supply pipe | tube 14 can be simplified, and the desired clearance gaps 27 and 28 can be formed.

(4)前記ねじ部材23と連結用アダプター18とは金属で形成され、それらのねじ部材23と連結用アダプター18にはそれぞれ当接面234、183が設けられ、当接面234、183が金属同士で面接触している。そのため、水栓本体151の軸線αと壁11との間隔xについて寸法精度を高めることができる。すなわち、ねじ部材23の当接面234と連結用アダプター18の当接面183とが金属同士で当接され、水栓本体151の軸線αと壁11との間に間隔xが保たれることから、カバー30の折曲げ部301と壁11の内面との間に隙間が形成されたり、カバー30の折曲げ部301が壁11の内面に強く当たってカバー30が湾曲したりすることはない。従って、カバー30の折曲げ部301と壁11の内面との間にシートパッキンを介在させる必要がなく、部品点数を少なくすることができる。これに対し、金属同士の当接部が存在することなく、ねじ部材23と連結用アダプター18との間にシール部材が介在されているのみでは、シール部材の潰れ変形度合いに応じて前記間隔xが変化するため、その変化を吸収するためのシートパッキンがカバー30の折曲げ部301と壁11の内面との間に必要になって、部品点数が増える。また、ねじ部材23及び連結用アダプター18の当接面234、183より外周側にはシール部材25が介装されている。このため、ねじ部材23と連結用アダプター18との間に金属同士の当接部が存在しても、それらの間の水密性を確保することができる。   (4) The screw member 23 and the connecting adapter 18 are made of metal, and the screw member 23 and the connecting adapter 18 are provided with contact surfaces 234 and 183, respectively. The contact surfaces 234 and 183 are made of metal. They are in surface contact with each other. Therefore, the dimensional accuracy can be increased with respect to the distance x between the axis α of the faucet body 151 and the wall 11. That is, the contact surface 234 of the screw member 23 and the contact surface 183 of the connecting adapter 18 are in contact with each other, and the distance x is maintained between the axis α of the faucet body 151 and the wall 11. Therefore, a gap is not formed between the bent portion 301 of the cover 30 and the inner surface of the wall 11, and the bent portion 301 of the cover 30 does not hit the inner surface of the wall 11 and the cover 30 is not curved. . Therefore, it is not necessary to interpose sheet packing between the bent portion 301 of the cover 30 and the inner surface of the wall 11, and the number of parts can be reduced. On the other hand, if the seal member is merely interposed between the screw member 23 and the connecting adapter 18 without the presence of a metal-to-metal contact portion, the distance x depends on the degree of deformation of the seal member. Therefore, a sheet packing for absorbing the change is required between the bent portion 301 of the cover 30 and the inner surface of the wall 11, and the number of parts increases. A seal member 25 is interposed on the outer peripheral side of the contact surfaces 234 and 183 of the screw member 23 and the connecting adapter 18. For this reason, even if the contact part of metals exists between the screw member 23 and the connection adapter 18, the watertightness between them can be ensured.

(5)前記アダプターは給水管13及び給湯管14に接続される管接続用アダプター16と該管接続用アダプター16に連結される連結用アダプター18とにより構成されている。このため、給水側脚部21と給水管13との接続及び給湯側脚部22と給湯管14との接続を容易に進めることができる。すなわち、給水管13及び給湯管14に管接続用アダプター16を接続して、その管接続用アダプター16をビス17で壁11に固定し、その固定状態の管接続用アダプター16に連結用アダプター18を接続すればよいので、接続作業が容易になる。   (5) The adapter includes a pipe connection adapter 16 connected to the water supply pipe 13 and the hot water supply pipe 14 and a connection adapter 18 connected to the pipe connection adapter 16. For this reason, the connection between the water supply side leg 21 and the water supply pipe 13 and the connection between the hot water supply side leg 22 and the hot water supply pipe 14 can be easily advanced. That is, a pipe connection adapter 16 is connected to the water supply pipe 13 and the hot water supply pipe 14, the pipe connection adapter 16 is fixed to the wall 11 with screws 17, and the connection adapter 18 is connected to the pipe connection adapter 16 in the fixed state. Therefore, the connection work is facilitated.
