To provide a grating through which pedestrians and automobiles can pass without slipping not only in fine weather but also in rainy weather.SOLUTION: A grating 1 is configured such that a plurality of main members 3 and a plurality of horizontal members 4, that connect the main members 3, extend in a grid pattern at regular intervals, and an upper surface 3a of each main member 3 is provided with a large number of anti-slip first protrusion parts 6 and second protrusion parts 7 protruding upward. An inclined surface 8 for preventing water retention, that is positioned gradually downward toward an outer side in a horizontal direction orthogonal to the main member 3, is provided at both side edges of the upper surface 3a of the main member 3.SELECTED DRAWING: Figure 2 【課題】晴天時だけでなく雨天時においても歩行者や自動車が滑ることなく通行することができるグレーチングを提供する。【解決手段】グレーチング１は、複数の主部材３と当該各主部材３を連結する複数の横部材４とが等間隔で格子状に延びるように構成され、各主部材３の上面３ａには、上方に向かって突出する滑り止め用の第１突部６及び第２突部７が多数設けられている。主部材３の上面３ａの両側縁部には、主部材３と直交する水平方向外側に行くにつれて次第に下方に位置する滞水防止用の傾斜面８が設けられている。【選択図】図２
