のである。FIG. 1 shows a hot water tank 6 of a local cleaning device such as an anal cleaning or bidet cleaning.
And a washing water outlet 8 for supplying washing water to a washing nozzle 7. A water supply hole 2 is provided in the water supply port main body 1, and one end of the water supply hole 2 communicates with the hot water tank 6 side, and the other end of the water supply hole 2 is open. The portion is provided with a fitting hole 3 having a diameter larger than that of the flowing water hole 2 and communicating with the flowing water hole 2. The constant flow valve 4 is made of an elastic body such as rubber, and has a small diameter portion 11 connected to a rear portion of the large diameter portion 10, and has a hole 12. The outer periphery of the front end of the large diameter portion 10 is partially provided with elastic projections 5 at three or more locations in the circumferential direction. A resistance device 25 for resistance to flow is fitted in the bottom of the hole 3 for fitting. The resistance device 25 has, for example, a shape as shown in FIG. The one shown in FIG.
An annular body 26 is formed integrally with the outer periphery of the radial body 27, and the annular body 26 is thicker than the radial body 27. A concave groove 28 is provided in the center of the radial body 27. And in FIG.
29 is a water outlet. With the resistance device 25 fitted in the bottom of the fitting hole 3 as described above, the constant flow valve 4 is fitted in the fitting hole 3, and the plurality of elastic projections 5 are fitted in the fitting hole 3. And the front surface of the constant flow valve 4 is pushed against the end surface of the annular body 26 of the resistance device 25 so that the resistance device is located between the constant flow valve 4 and the bottom of the fitting hole 3. It holds 25. Here, the concave groove 28 at the center of the radial body 27 faces the hole 12 of the constant flow valve 4. A strainer 14 is further fitted into the fitting hole 3, and the strainer 14
The 14 flange 15 is pressed against the end face of the water supply port main body 1 via the packing 16, and in this state, the external thread portion of the outer periphery of the water supply port main body 1 is formed.
17 is screwed with a cap nut 19 externally fitted to the front end of the water pipe 18 to form a flange 20 at the front end of the water pipe 18 with the flange 15 of the strainer 14,
It is attached while being pressed against the end face of the water supply port main body 1 via the packing 16. Thus, the water from the water pipe 18 flows into the fitting hole 3 through the strainer 14 and flows into the flowing water hole 2 through the hole 12 of the constant flow valve 4. If the diameters are different, the diameter of the hole 12 changes in accordance with the pressure of the tap water applied to the elastic constant flow valve 4 in the fitting hole 3, and as a result, the constant flow rate flows. Then, the water flow which is made constant flow by the constant flow valve 4 and flows out from the front end of the hole 12 hits the concave groove portion 28 at the center of the radial body 27 of the resistance device 25, and the water flow is buffered, and along the radial body 27 It flows through the water outlet 29 and flows into the water hole 2, and this resistance device
When passing through 25, the water flow is buffered and cavitation is prevented. By the way, water supply pressure 2-6 kg / cm 2
On the other hand, there was an effect of reducing the sound pressure by about 4 to 10 dB. When the constant flow valve 4 is to be removed for replacement of the constant flow valve 4 or the like, the cap nut 19 is removed, the strainer 14 is removed, and then the small diameter portion 11 of the constant flow valve 4 is grasped with a finger and removed. However, in this case, the constant flow valve 4 has elastic projections 5 partially provided at three or more places in the circumferential direction on the outer periphery thereof and is in elastic contact with the inner peripheral surface of the hole 3 for fitting. It is easier to remove than when elastically mounted.

This resistance device 25 is configured by connecting a large disk 30 having a hole 30a in the center and a small disk 31 with a plurality of spacers 32, and further providing a plurality of legs 33 on the small disk 31. Part 32
The gaps between the legs and the legs 33 are gaps through which the water flows. Also in this embodiment, the constant flow valve 4 made of an elastic body is used.
