Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a piping device having a flow passage for discharging fluid such as drain water and feed water, and forming an air space part which is sealed therein, in which air in the air space part is reduced at the discharge of fluid, and which has a mechanism for preventing the filling and backflow of drain water.SOLUTION: There is provided a rectifying member 10 having a rectifying part 11 with which expanded water (fluid) directly collides at a position immediately below an inlet port 6 being the downstream side of an air space part 20, the rectifying member 10 has the protruded rectifying part 11, an inclined face 13 and a water passing part 12, and the expanded water which collides with the rectifying part 11 is landed on a water-sealing water surface while passing through the inclined face 13 and the water passing part 12. Therefore, the expanded water is discharged to the downstream side without entangling air in the air space part 20.
