<p><P>PROBLEM TO BE SOLVED: To provide a washing nozzle device for washing a private part, capable of washing the private part with a relatively small amount of water while restricting the amount of water in a water supply chamber with the throttling operation of a variable throttle passage when washing the private part, and capable of reliably and quickly advancing and elongating a nozzle with a large amount of water when advancing the nozzle. <P>SOLUTION: The nozzle device includes a nozzle 2 a pressure receiving part 24 of which has an elastically deformable elastic body 4, a hard body 5 having a pressure receiving surface 58 for receiving the water pressure of a water supply chamber 10, and formed of a material harder than that of the elastic body 4, and a water pressure responsive variable throttle passage 6 formed in a boundary region between the elastic body 4 and the hard body 5. The variable throttle passage 6 is variable in the throttle degree. The elastic body 4 and the hard body 5 pressed against each other with an increase in the water pressure of the water supply chamber 10 increases the throttle degree to restrict the amount of water passing therethrough. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
