PROBLEM TO BE SOLVED: To provide a catchment grating having improved draining performance while effectively maintaining traffic safety by properly dropping down water flowing on the flowing water surface of a road while preventing the occurrence of a level difference. SOLUTION: The catchment grating 1 comprises a guide member 20 having a water guide surface 19 inclined greater than a vertical gradient of the flowing water surface 6 of the road, a crossing member 22 arranged on the downstream side of the guide member 20 with a downward opening catchment road 23 laid therein, having an upper edge face 22A at a position higher than a downstream side portion of the guide member 20 and extending in the crossing direction, and a plurality of leveled-up ribs 24 for connecting the members 20, 22 to each other to cover an elevation difference between the water guide surface of the guide member 20 and the upper edge face 22A of the crossing member 22.
