The valve element 44 and the rod 46 also try to return to the position shown in FIG. 1 by the urging force of the spring 72, but the flow rate in the working chamber 58 is extremely small through the narrow gap between the small hole 66 and the shaft 68. Water flows in, so that the valve element 44 slowly moves in the upper left direction in FIG. 1 at a speed commensurate with the minute inflow speed of this water. Eventually, the valve element 44 (packing 42) contacts the partition wall 38, the opening 40 is closed, and water is stopped.

A reference numeral 92 in FIG. 1 is a cap nut attached to the outflow port 22 of the currant block 36, and holds a rectifying net 94.

The self-closing valve 24 also has the same structure as the self-closing valve 26. When the handle 24A is pushed, water discharge is started from the shower spout 20, and after the hand is released from the handle 24A, a required time elapses. It is automatically stopped.

[0017]

[Problems to be solved by the device]

 In the conventional handle 26A, the cases 26a, 26b and 26d are integrated by the screw 26e, but there is a problem that the screw 26e is easily lost when the handle is assembled.

That is, the screw body 78 is rotated to move forward or backward to adjust the position of the rod 46 and adjust the water discharge continuation time. It is necessary to remove 26e to remove the outer case 26a from the inner case 26b, and then remove the pin 84 to remove the inner case 26b from the convex portion 74. On the contrary, after the screw 78 is adjusted by turning, it is assembled in the reverse order to the above, and finally the screw 26e is tightened.

By the way, the screw 26e is attached to the lower side of the handle 26A so as not to be conspicuous to the faucet user, and the mounting work posture becomes difficult, and at the same time, the cases 26a, 26b, 26c. It is not easy to match the screw holes of. In addition, the screw 26e itself is small in the first place. For this reason, there were problems such as the workability of tightening the screw 26e was poor, and the screw 26e dropped from the hand fell into the drainage ditch of the bathroom.
