<p>A nozzle device (500) has a nozzle portion (700) comprising a jet outlet and a channel, a supporting portion (600), and a driving unit (800) comprising a flexible rack (810). The supporting portion (600) comprises a retaining unit (630), a guide rail (621), a rack guide (622) that guides the flexible rack (810), and a sliding unit (750) that engages with the guide rail (621). The flexible rack (810) is joined to the sliding unit (750), and the driving force imparted to the nozzle portion (700) acts between the retaining unit (630) front end and the sliding portion (750) back end. Thus, the nozzle portion (700) is capable of smoothly sliding and having a stable trajectory of motion, and the jet outlet of the nozzle portion (700) can move to a suitable washing position.</p> |
