PURPOSE: To obtain the title washing nozzle capable of certainly washing an object to be washed even when the position of the object to be washed such as the hand changes by forming an air jet orifice to the periphery of a liquid jet orifice for jetting a washing liquid.
CONSTITUTION: A washing nozzle for weightless space is constituted by forming a water jet orifice 11a to the tip of a jet nozzle 11 and arranging an air jet nozzle 13 for jetting air A so as to surround the water jet nozzle 11. The water W flowing in the water jet nozzle 11 from a water supply port 11b is jetted from a water jet orifice 11a and the air A flowing in the air jet nozzle 13 from an air supply port 13b is jetted from an air jet orifice 13a. By this constitution, the air A jetted from the air jet orifice 13a is always present around the water W jetted from the water jet orifice 11a and the water W bonded to the hand is certainly blown off by the air A and, therefore, even when the position of the hand changes, the hand can certainly be washed.
