Abstract
A novel water jetting device achieves a water jet of a wide range and an economization of water without using an electric drive device. A water jetting body 10 is so vortex chamber 4 with its water jetting spout 11 confronting the outside of the force receiving member 12 that a force receiving member 12 can oscillate in a position inclined in the vortex chamber 4. A vortex flow thus established in the vortex chamber 4 is caused to make a flow velocity difference around the force receiving member 12, and a force generated on the basis of the flow velocity difference is exerted upon the force receiving member 12 to oscillate the water jetting body 10 in the inclined position in the vortex chamber 4 thereby to jet the cleaning water in the vortex chamber 4 from the water jetting spout 11.
