A drain unit for a sink bar having a rust prevention structure is provided to prevent corrosion of a bucket unit by ejecting gas to the drain unit which is connected to a drain pipe. A drain unit for a sink bar having a rust prevention structure includes a bucket unit, a drainage basin(20), a filtering net(30), a bad smell prevention cap(40), and an over-flow pipe. The drainage basin has a drain port(21) installed on a bottom plane of the bucket unit and connected to a drain hose, and an open port(22) connected to the over-flow pipe. The filtering net is installed inside of the drainage basin. The bad smell prevention cap is installed at a lower part of the filtering net and prevents a bad smell from flowing backward through the drain port. An inner side of an inlet of an open port is formed at a lower position than a water level of the drainage basin and a lower end of the bad smell prevention cap. |
