According to the configuration of the invention, a plate material having a length substantially the same as the length of the grating is inserted into one of the grooved grooves formed on one side end surface, so that the width of the side groove is the grating. Even if it is larger than the effective width, the grating can be easily adapted to the side groove. By hanging the latching portion of the plate material on one upper edge of the side groove and the other ear plate of the grating on the other upper edge, the grating is stably attached to the upper surface of the side groove, and the upper surface of the side groove is closed freely. Because it can. Since the stopper on the back surface side of the plate material can be adjusted to move in the width direction of the grating, it is prevented from shifting the position of the grating by fixing it at an appropriate position according to the width of the side groove.
[0011]
By gradually decreasing the thickness of the latching portion in the width direction of the plate material, the latching portion can be continued to the road surface of the upper edge of the side groove via the slope, thereby facilitating the passage of the vehicle or the like. Further, the latching portion can be easily adapted to the case where the height of the upper edges of both sides of the side groove is different by bending the obtuse angle in the width direction of the plate material. In this case, the grating can be attached to both sides in the width direction, and can be stably and obliquely attached to the side grooves regardless of the difference in height between the upper edges of both sides of the side grooves.
[0012]
By making the latching part a separate member that is flexibly connected via a hinge, it is possible to more easily absorb the difference in height between the upper edges of both sides of the side groove.
