It is formed mainly from

In this example, the water faucet 4 is a self-closing faucet that opens by pressing the lever handle 6 downward, and after releasing the pressure, discharges a predetermined amount of water and automatically closes the valve. It is erected through the counter 5 and is connected to the water stop valve 7 via a water supply pipe 8 .

The secondary side chamber of this faucet 4 has an outflow tube 9 in a direction substantially perpendicular to the axis of the faucet 4, and a socket 10.
A supply pipe 12 to a water discharging device is connected via a cap nut 11.

The water discharging device includes a water discharging device main body 20 located on the front side of the front panel 2, a connecting tube 21 to which the water discharging device main body 20 is fixed by spline engagement, and a connecting tube with the supply pipe 12 located on the back surface of the front panel 2. 21, and a foam cap 24 is attached to the spout 20b of the water spout main body 20 via a screw tube 40.

The water spout main body 20 has a connecting tube mounting port 20a and a water spout 20b on different axes for attaching a connecting tube 21 and a foam cap 24, respectively.
On the side, a large diameter part 25, a spline part 26, and a small diameter part 27 are formed in steps from the open end toward the inside, and a screw hole 28 is provided on the lower surface side of the water spout main body 20 in a part corresponding to the spline part 26. It has been established.

In addition, in FIG. 3, 40 is a screw threaded to the spout 20b to connect the foam cap 24;
41 is a rectifying net placed inside the foam cap 24 via a packing 42.

The connecting tube 21 has a flange 29 located in the large diameter portion 25 of the water discharging device main body 20 and abuts against the surface of the front panel 2 in the middle, and has a screw 43 formed at one end to connect the joint 22.
