To provide a portable type private part washing device to permit sanitary use by structuring so that a washing liquid storing part and a water discharge mechanism to send the washing liquid by pressure to a nozzle are installed in the device body which is formed as capable of being carried around, installing an ultrasonic oscillator, and splashing away the water drops, etc., attached to the surface of the nozzle, etc., in good performance with the vibration given from the oscillator.

A portable type private part washing device is composed of a body part 2 and a nozzle 4, the latter 4 being arranged rotatable with respect to the former 2 in the range from the accommodating position located under the body 2 to the service position protruded forward centering on the rotary shaft. A washing liquid storage part 8 to store the washing liquid is installed inside the body 2, and a water discharge mechanism 9 is installed beside the storage part 8, and is equipped internally with a pump 11 in a pressure feed pipe 10 leading from the storage part 8 to the nozzle 4 and with an opening/closing valve 12 at the outlet. The nozzle 4 is internally fitted with an ultrasonic oscillator in the neighborhood of the jet hole and vibrated with actuation of the oscillator so that the washing liquid, urine, etc., on the nozzle surface are splashed away.
