PROBLEM TO BE SOLVED: To prevent inconvenience due to remaining water in a nozzle from generating without particular construction or operation by washing the private parts by discharged water from an extensible nozzle, and executing the extension/contraction movement without discharging water from the nozzle after self cleaning washing of the nozzle discharge port part. SOLUTION: Output of a nozzle motor 3 is transmitted to a pulley to extend/ contract a nozzle 1 and wash the private parts, and for keeping clean the vicinity of the nozzle discharge port part 5 after washing the private parts, the discharge port part 5 is washed by self cleaning in the vicinity of the watering prevention wall 7 of a washing chamber 6 covering the discharge port. After discharging the self cleaning washing water, the nozzle 1 is extended/contracted without discharging water from the nozzle 1, to bring out the discharge port from the washing chamber 6 of the nozzle 1. Hereby, surface tension of water generated in a small clearance between the watering prevention wall 7 and the discharge port part 5 of the nozzle 1 is broken, remaining water in the nozzle flows out from the discharge port of the nozzle 1, and the remaing water quantity in the nozzle until succeeding washing can be reduced.
