PROBLEM TO BE SOLVED: To provide a low-cost washing device for a human body private part with a function to pulsate washing water.SOLUTION: A washing device for a human body private part includes a pressure adjustment switching valve that adjusts pressure of washing water W, a pulse generation part 43 that pulsates the washing water W, and a controller. The pulse generation part 43 is supplied with the washing water W, and includes a valve chamber 43a connected to a jet hole 42, a shaft valve body 43c disposed movably in the valve chamber 43a according to an adjusted pressure, which is a pressure of the washing water W adjusted by the pressure adjustment switching valve, for opening/closing the jet hole 42, and a spring 43e that energizes the shaft valve body 43c against the adjusted pressure. The controller includes a pulse controlling part that controls pulse for pulsating the washing water W by the pulse generation part 43, by adjusting the adjusted pressure to a pulse generating pressure that makes the shaft valve body 43c undergo a periodic reciprocating motion for opening/closing the jet hole 42, using the pressure adjustment switching valve.SELECTED DRAWING: Figure 6 |
