PURPOSE: A vortex tube is provided to control the discharged amount and temperature of cold and hot air through cold air and hot air discharge holes depending on the supplied amount of compressed air. CONSTITUTION: A vortex tube(1) comprises a vortex chamber, a tube body(10), a vortex forming member, and a shield valve(40). An air supply port and a cold air exhaust hole are formed in the vortex chamber. A hot air exhaust hole is formed in the tube body. The vortex forming member is received in the vortex chamber and circulates compressed flowing into the vortex chamber. The shield valve is arranged on the hot air exhaust hole and controls the opening degree of the hot air exhaust hole.
