PROBLEM TO BE SOLVED: To provide a grating capable of simply cleaning fallen leaves, dust or the like even when the fallen leaves, dust or the like accumulate on a grating. SOLUTION: The grating is placed astride over the top faces of both side walls 2 of a drain gutter 1. In the grating, a base plate 10 bent and formed by alternately continuing crest sections 11 and bottom sections 12 in the flowing direction of the grain gutter 1 and made of a synthetic resin is mounted. In the grating, a protrusion 13 for preventing a positional displacement is formed at a place brought into contact with the side wall 2 of the drain gutter 1 on the rear of the base plate 10, and a water permeable member 30 removing dust flowing in the drain gutter 1 is fitted on the rear of the corrugated base plate 10.
