Abstract
A water spraying nozzle of the present invention is constructed of a relatively small number of parts which can be easily assembled to produce the water spraying nozzle at a low cost, which nozzle is easy in handling to enable any user to smoothly operate it without any special training. In the water spraying nozzle of the present invention, the outer and intermediate sleeves employed in the conventional water spraying nozzle are replaced with a novel controlling sleeve comprising an inner and an outer sleeve portions enabling the user to operate the water spraying nozzle in a very simple manner.
