The diaphragm valve 20 is fitted between the forming members 15, and the pressure chamber S is formed between the downstream side surface of the diaphragm valve 20 and the pressure chamber forming member 15.

An insertion shaft 15b is provided at the central portion of the pressure chamber forming member 15 so as to project upstream, and the insertion shaft 15b is loosely inserted into the central portion of the diaphragm valve 20. . The diaphragm valve 20 is brought into contact with the seat portion 14c formed in the flow passage pipe 14 to contact the flow passage R1.
Is arranged so that it can be closed. In addition, the flow path pipe 14
A hole 14b is formed outside the seat portion 14c. Further, the pressure chamber forming member 15 is formed with a connecting pipe portion 15a extending to the downstream side, and a pressure reducing valve 16 is internally provided in the connecting pipe portion 15a.
It is designed to flow water with a water pressure of 5 kgf / cm ² or less. A thin pipe 17 is connected to the connecting pipe portion 15a, and the inside of the thin pipe 17 is a pressure water passage R2 for passing pressure water.
The thin tube 17 is passed through the shower hose 9 and extended to the shower head 10 side. The thin tube 1 passed through the shower hose 9
A flow path R1 is formed between the outer circumference of 7 and the inner circumference of the shower hose 9. The shower hose 9 is connected to the case portion 13 via a connection socket 18, a cover body 19 and the like.

A flange portion 17a is formed at the downstream end of the thin tube 17 as shown in FIG. 4, and a plurality of concave grooves 17b are formed at predetermined intervals on the outer periphery of the flange portion 17a. There is. As shown in FIG. 3, the collar portion 17a of the thin tube 17 is fixed to the downstream end of the flow path R1 of the shower head 10, and the flow path R1 communicates with the discharge side of the shower head 10 through the concave groove 17b. It is supposed to be done. Also,
A spring 21 is provided inside the opening / closing operation button 11 (opening / closing operation portion) provided on the upper surface of the shower head 10. By pressing the opening / closing operation button 11, the internal valve shaft 22 is moved downward.

The valve element 23 is moved upward so that the opening at the downstream end of the pressure water passage R2 of the thin tube 17 is opened.

In such a configuration, when the switching handle 2 of FIG. 1 is switched to the shower side, water is discharged from the faucet body 1 to the shower side elbow 5 side, and the discharged water flows into the flow passage pipe 14, At this time, in the state where the opening / closing operation button 11 on the shower head 10 side is pressed and the valve body 23 abuts on the collar portion 17a of the thin tube 17 to close the pressure water passage R2, the pressure water passage R2 and the communication therewith are communicated. Pressure chamber S
Water is sealed inside, and the water pressure applied from the pressure chamber S to the diaphragm valve 20 causes the diaphragm valve 20 to be closed.
Is pressed by the seat portion 14c to close the seat portion 14c,
The water pressure applied to the diaphragm valve 20 from the pressure chamber S and the water pressure applied to the diaphragm valve 20 from the flow path pipe 14 are equal, but since the pressure receiving area for the diaphragm valve 20 on the pressure chamber S side is set to be large, Valve 20
Is to be kept in contact with the seat portion 14c to close the flow path R1.

Therefore, in the state where the pressure water passage R2 and the pressure chamber S are sealed, the shower head 10 is connected to the shower head 10 through the flow passage R1.
No water is discharged to the side. When the user presses the open / close operation button 11 in this state, the valve body 23 is opened, and water in the pressure water passage R2 escapes,
As a result, the water pressure in the pressure chamber S is reduced, and the water pressure in the flow passage R1 on the flow passage pipe 14 side is overcome, whereby the diaphragm valve 20 is pressed downstream and the diaphragm valve 20 separates from the seat portion 14c, and the flow Water from the passage R1 passes through the hole 14b, the inside of the case portion 13 outside the flange portion 14a, the passage R1 formed between the outer periphery of the thin tube 17 and the inner periphery of the shower hose 9, and the shower head 10 And shower water can be discharged from the shower head 10. When the user presses the opening / closing operation button 11 again, the valve body 23 is brought into contact with the flange portion 17a and the pressure water passage R2 is closed, so that the pressure of the sealed pressure chamber S causes the diaphragm to be closed. The valve 20 is pressed upstream and abuts the seat portion 14c to close the flow path R1.

Thus, in this example, the shower head 10
