PROBLEM TO BE SOLVED: To prevent the discharge flow from being influenced by the water supply pressure, to surely prevent the occurrence of water hammer and vibration, and to reduce the quantity of washing water in a bidet adapted to intermittently discharge water. SOLUTION: This bidet includes a water feed means 1, a pressuring means 3 for periodically discharging variable pressures taking a higher pressure than the water supply pressure supplied from the water supply means 1 as a center value, and a discharge means 4 for discharging water pressurized and supplied by the pressure means 3 as washing water. The water supply means 1 has a pressure regulating part. The pressurizing means 3 is a reciprocating pump having a plurality of pump chambers, and the phases of piston operation in the respective pump chambers are shifted from each other. The pressure variable cycle of the pressurizing means 3 is a pressure fluctuation cycle recognized by the human body. COPYRIGHT: (C)2003,JPO
