PROBLEM TO BE SOLVED: To provide a grating capable of improving workability when the grating is installed on a ditch block.SOLUTION: A grating 1 comprises a grating body 31 and multiple engaging members 32. The engaging member has a rod-like body 41, a rotation body 42, and a stopper 43. When an operation part 46 of the rod-like body is rotated after the grating body is laid on a first protrusion 11 and a second protrusion 12 of a ditch block, the rotation of the rotation body that integrally rotates with the rod-like body is restricted by the stopper that contacts a contact part. The engaging member is constituted so that, when the operation part is further rotated in the rotation restricted state, a screw part 47 of the rod-like body is tightened by a fastening part 49 of the rotation body, and that an engaging part 50 of the rotation body latches the first protrusion or the second protrusion from below to restrict movement of the grating body upward.SELECTED DRAWING: Figure 8 |
