To provide a drain structure of a sloped floor surface part capable of smoothly guiding and draining a surface moisture flowing down along the sloped floor surface part toward a drain without forming a side gutter at a downstream side edge portion.
This drain structure is formed in an underfloor ground (sloped floor surface part) 11 with drain gradient for flowing down the surface moisture toward the drain 12 disposed at the downstream side edge portion 11a of the underfloor ground 11. The drain structure extends in a diagonally downstream direction relative to the direction Y perpendicular to the diagonal direction X of the drain gradient extending toward the downstream side edge portion 11a along the downstream side edge portion 11a of the underfloor ground 11. A step wall part 14 forming a step surface 13 opposed to the diagonal direction X and having the end facing the drain 12 projects upward from the underfloor ground 11. Also, floor finishing members 15 are so fitted as to cover the underfloor ground 11 while holding a gap s for flowing down the surface moisture between itself and the underfloor ground 11.
