Thus, the hot water passing through the water spray plate 53 is not completely shut off, thereby suppressing an increase in the water pressure inside the water flow space S, and the rotation of the impeller 54 is not hindered. It is comprised so that a pulsed water flow can be continuously discharged from the exit 513.

  Further, the plurality of second water passage holes 534 are arranged in a dispersed manner, that is, the opening 546 is opposed to any one of the second water passage holes 534 regardless of the rotational position of the impeller 54. Thus, the increase in water pressure accompanying the rotation of the impeller 54 can be effectively suppressed, and the rotation of the impeller 54 is smoothly continued. On the other hand, when the opening area of the second water passage hole 534 is too large, the amount of hot water passing through the first water passage hole 533 is relatively reduced, so that it is difficult to form a pulsed water flow. However, since the opening area of the first water passage hole 533 is larger than the sum of the opening areas of the second water passage holes 534, the flow rate of the water flow through the second water passage hole 534 can be suppressed. . Here, the opening area of the first water passage hole 533 is set to about 2.5 times the total opening area of the second water passage hole 534 in FIG. 8, and is set to 10 times or less. It is preferable. By setting it as such an opening area, the flow volume of the main water flow which goes to the water outlet 513 from the 1st water flow hole 533 can be ensured, and this main water flow can be discharged from a water outlet as a pulse form.

The second drainage port 76 communicated in this way, the on-off valve 77 that opens and closes the second communication space 75 by moving with the pressure of the water flowing from the first supply port 71 to the first drainage port 73, and the on-off valve 77 in the closing direction. And a compression spring 78 as an urging means for urging the lens.

  A pipe 81A from a switching valve for the overhead shower section 14 (a switching valve connected to the second operation section 24 from the top) is connected to the first supply port 71 of the first residual water drain valve 28A. The first supply port 71 of the residual water drain valve 28B is connected to a pipe 81B from a switching valve for the hot water hot water section 15 (a switching valve connected to the uppermost operation section 24). Hot water mixed with the hot water mixing valve 29 is supplied to each switching valve, and hot water is supplied from each switching valve to the first supply port 71 via the pipe 81 by operating each operation portion 24 to the cold water drainage position. It has come to be. Further, a pipe 82 is connected to the first drain outlet 73 of the first residual water drain valve 28A and the second residual water drain valve 28B via a joint 82A that combines them into one. 12 is connected.

  A residual water pipe 83A connected to the overhead shower section 14 is connected to the second supply port 74 of the first residual water drain valve 28A, and the second supply port 74 of the second residual water drain valve 28B is struck. A residual water pipe 83B connected to the hot water part 15 is connected.
