PROBLEM TO BE SOLVED: To prevent damage in a lower part of a vehicle by removal, floating or flip-up of a side ditch cover from a side ditch.SOLUTION: A body 1 comprises a plurality of covers 2 continuously connected. Elliptic holes 5 opened in lower frames 2b of the covers 2 move upward and downward with respect to shafts 3, to release force directly applying on one of the covers 2. In addition, a free shaft 4 and a free shaft 4a are connected and continuous covers 2 are vertically floated respectively and independently, to disperse the force. Thus, the body 1 is not removed from a side ditch and the cover is not flipped up.SELECTED DRAWING: Figure 1
【課題】 側溝の蓋が側溝より外れたり浮き上りや跳ね上げにより車両の下部を損傷させないこと。【解決手段】 本体１は複数の蓋２が連続して結合されているが蓋２の下部枠２ｂに開けられた楕円状の穴５がシャフト３を上下に動くことで蓋２の１枚に直接掛る力を逃がし、さらに自在シャフト４と自在シャフト４ａを結合しているため連続した蓋２はそれぞれ独立して上下に浮き上がることで、力を分散し本体１が側溝より外れず、蓋が跳ね上がらない。【選択図】図１
