A ventilator for a cold cathode fluorescent lamp is provided to minimize a power loss and maximize a cleaning efficiency by preventing a rinsing gas from being leaked out of a rotation valve. Lamp tube holders are arranged in a circumferential direction. A through-hole is formed in a center portion of a rotation table(250). A tube type rotation shaft(260) supports the rotation table at a constant height. Holder mounts are arranged on upper and lower portions on an outer periphery of the rotation shaft. A driving unit is shaft-coupled with a lower end of the rotation shaft. The driving unit is embedded in a base case(60). A gas cleaner(120) and a vacuum pump(100) are fixed on the holder mounts, respectively, and connected to the lamp tube holder. A tube type fixing shaft(270) is shaft-coupled with the rotation shaft. A rotation electrode unit(220) is shaft-coupled with an upper end of the fixing shaft and supplies the power from the outside to the gas cleaner and the vacuum pump.
