At this time, the drainage is gradually drained into the drainage horizontal pipe 3 from the lowermost end of the drainage port 2 located beside the shielding wall 4 formed in the drainage port 2. Then, the drainage water level rises in the drainage horizontal pipe 3 and air is stored in the upper part of the drainage horizontal pipe 3, but the drainage port of the drainage device 1 is opened from the opening provided above the shielding wall 4 of the drainage port 2. The air in the air pool flows backward in the direction 71, and the air in the air drainage horizontal pipe 3 is discharged to the outside of the drainage device 1, specifically, toward the drainage port 71 of the tank body 7. Accordingly, since there is no air pool in the drainage horizontal pipe 3, the flow of drainage is not hindered by the air pool, and the drainage flow rate is improved.
The drainage in the drainage horizontal pipe 3 is finally drained into the sewer pipe. Moreover, since the trap part 6 is comprised in the drainage device 1, the odor and pest from a sewage do not flow backward indoors.
