Water discharging device

A water jetting device comprising a nozzle, for jetting from the nozzle cleansing water supplied thereto, wherein the nozzle has;

• an inflow chamber into which cleansing water flows,
• a water jetting body assembled in the inflow chamber, having a water jetting member comprising a cleansing water jetting spout and a chamber-housed member continuous with the water jetting member and situated within the inflow chamber, the water jetting body having a conduit for guiding cleansing water in the inflow chamber to the water jetting spout, and
• a water supply mechanism for guiding cleansing water into the inflow chamber in such a way that vortical flow around the chamber-housed member along the inside peripheral wall of the inflow chamber is created in cleansing water flowing into the inflow chamber,
• the water jetting body is assembled in the inflow chamber with the water jetting spout located in proximity to the exterior of the inflow chamber, such that the chamber-housed member is capable of swinging in an inclined attitude within the inflow chamber,
• the water supply mechanism generates a flow velocity differential in the vortical flow around the chamber-housed member, the force generated on the basis of the flow velocity differential exerting influence on the chamber-housed member whereby the chamber-housed member at an inclined attitude within the inflow chamber induces swinging motion and revolution of the water jetting body.
