Description

  The present invention relates to a water tap connected to a hot water supply pipe and a water supply pipe disposed on a wall surface or a floor surface.

  Conventionally, for example, in a bathroom or the like, as shown in FIG. 7, crank-shaped mounting legs B and B are respectively connected in front of a hot water supply pipe H and a water supply pipe C disposed on a wall surface W. A mixing faucet A was attached to the other end. These mounting legs B and B absorb this error even if there is an error in the left and right distance between the hot water inlet and the water inlet of the mixing faucet A with respect to the left and right distance between the hot water supply pipe H and the water supply pipe C. The mixing faucet A is attached to the pipe, but by using the mounting legs B and B, the amount of forward projection from the wall surface of the mixing faucet A increases, and the bathroom space is narrowed. there were. Therefore, in recent years, a mixed faucet that can be directly attached to a wall surface without using a mounting leg, that is, a mixed faucet with a small amount of forward protrusion from the wall surface has become widespread. A known stopper is one disclosed in Patent Document 1.

  This Patent Document 1 will be briefly described with reference to FIGS. 8 and 9. The hot water pipe 71 and the water pipe 72 provided on the wall surface 69 are connected to the hot water inlet 52 and the water inlet 53 of the mixing faucet 51. Each of the connecting pipes 64 and 64a for hot water and water and an opening 56 formed on the outer periphery of the connecting pipes 64 and 64a and through which the male screw portions 65 and 65 connected to the pipes 71 and 72 are inserted. A faucet fixture 54 is composed of one plate 55 and a second plate 60 having an aperture hole 61 communicating with the aperture hole 56. After the faucet fixture 54 is attached to the wall surface 69, a mixed faucet 51 is attached and fixed to a faucet fixture 54.
