<p>PROBLEM TO BE SOLVED: To diversify washing forms for washing of a private part, which uses a movable water discharge part having a water discharge hole. SOLUTION: While a washing nozzle 24 is reciprocated back and forth, the hole 25c for discharge of water to buttocks is swung so that an angleαof horizontal swing of the hole 25c can vary greatly or slightly in a repeated manner. The washing water is discharged from the hole 25c only in a case where the hole 25c is located at a starting point Sa of a forward swing and an intermediate point Sb serving as a turning point. Consequently, in each arrival-of-water position, there is brought about the thick and voluminous washing water based on coalescence of the washing water by virtue of pulsation water supply and water discharge.</p> |
