PURPOSE: A nozzle washing device for a salt spray tester is provided to eliminate salt by supplying purified water to an air supply line, and to reduce test hours and improve reliability. CONSTITUTION: A salt spray tester(50) is composed of a salt water supply unit(51), an air supply unit(52) and a nozzle(53). A salt water supply line(54) and an air supply line(55) are connected between the salt water supply unit, the air supply unit and the nozzle. The nozzle receives salt water from the salt water supply unit and air from the air supply unit, and has a salt water injection hole(60) in the middle and air injection holes(61) at both sides. The salt injection hole is integrated with the air injection hole in a tip(62). A washing apparatus(80) having a purified water supply unit(81) is placed in the air supply line, and the air supply line is connected to a purified water supply line(82). A solenoid valve(83) selects purified water supply, and a regulator(84) decides the supply amount of purified water. The nozzle washing device cleans and eliminates salt from the tip by supplying purified water to the air supply line of the salt spray tester.
