PROBLEM TO BE SOLVED: To provide a drainage trap capable of preventing a leakage accident due to closing of a flow channel caused by dust in discharge water.SOLUTION: In a drainage trap 100, trap members 113 and 114 comprise a first opening part 113a which has a shape of a tube with the lower part closed and which opens on the upper end of the tube, a tabular partition part 114a which separates from the lower part in the tube and which is integrally formed in the side and upper parts of the tube so as to partition the inside of the tube, an U-shaped flow channel part 113b formed in the tube by the partition part, and a second opening part 113c which is at a downstream side of the flow channel part and which is formed by penetrating a tube wall. The trap members cause drainage to flow into from the first opening part, store the drainage in the flow channel part, and discharge from the second opening part. A trap body houses the trap members at least up to the second opening part, and discharges drainage flowing in downward from the second opening part toward a lateral side while storing the drainage on the bottom. A sealing member seals the space between the trap members and the trap body and limits a flow of medium.SELECTED DRAWING: Figure 2 |
