PURPOSE: A water spray gun using water pressure is provided to reduce manufacturing cost by using components having simple structure, and to spray water uniformly in a semicircular region. CONSTITUTION: A water spray gun using water pressure is assembled to change a direction of a pressure plate(4) by rotating a cam(8) connected to a blade. A second and a third gears(12,13) are moved with a gear bonding with a bearing(10). The second and the third gears are connected with the cam of the blade. The water is discharged through a nozzle(3). The pressure of the water pushes the blade connected with the pressure plate downward. The water spray gun sprays the water while rotating in a setting angle gap.
