PURPOSE:To facilitate automatic switching of a water discharge form in a simple structure and to prevent a backlash at the completion of switching drive. CONSTITUTION:A rotary water discharge unit 23 having plural different water discharge forms is provided on a water discharge switching portion 22 of a water discharge portion B, and a rotary shaft 29 integrally vertically arranged in the center thereof is connected to a geared motor 66 having a speed reducing function, which is disposed below a potentiometer 65 of an electric driving portion 64 provided on a shower head D. The geared motor 66 can accomplish correct rotary positioning by adopting a non-backlash system for limiting the rotating direction to one way, whereby the rotary water discharge unit 23 is rotary-driven according to the control of a control portion 67 to position one of desired water discharge nozzles 24-27 in a water discharge window 30. |
