Zusammenfassung:To provide means to prevent damaging of a lower part of a vehicle or derailing of a vehicle, or to improve safety of a pedestrian, such troubles being caused by a situation where a grating in a gutter comes off, comes up, or bounces up from the gutter.SOLUTION: A main body 1 and gratings 2, respectively, do not come off from a gutter and do not bounce up, as a result of allowing bolts 3 to move up and down independently in oval-shaped holes 4 opened in lateral end plates 2h of the gratings 2 although the main body 1 is combined by the plural gratings 2 back-to-back, thereby dispersing external force by allowing each of the back-to-back gratings 2 to independently move up and down, right and left, to allow the external force directly exerted to one of the gratings 2 to be released.SELECTED DRAWING: Figure 1 【課題】 側溝のグレーチングが側溝より外れたり浮き上がりや跳ね上げにより車両の下部を損傷させないことや車両の脱輪防止や人の歩行時の安全性の向上。【解決手段】 本体1は複数のグレーチング2が連続して結合されているがグレーチング2の側面エンドプレート2hにあけられた楕円状の穴4をボルト3がそれぞれ独立して上下に可動することでグレーチング2の1枚に直接かかる外力を逃がすよう連続した各グレーチング2がそれぞれ独立して上下左右に可動することで力を分散し、本体1が側溝より外れず、グレーチング2も跳ね上がらない。【選択図】図1
