The attenuation of the ultrasonic waves can thus be suppressed and the washing effect enhanced. Further, the air bubbles generated within the pipe 3 and the nozzle body 1 escape from air vent piping 4 but the piping 4 is disposed on the upper side of the pipe 3 and the outflow of the washing liquid from the piping 4 decreases and therefore the pressure drop of the washing liquid jetted from the liquid spout a can be prevented and the washing effect enhanced.  <P>COPYRIGHT: (C)2004,JPO
