PROBLEM TO BE SOLVED: To provide a structure for preventing falling of vehicle lower part closing plates, which can prevent the vehicle lower part closing plates from falling from lower face opening receiving parts without requiring new operation when the vehicle lower part closing plates are inserted into the lower face opening receiving parts of a vehicle body and arranged at a predetermined position.SOLUTION: In a structure for preventing falling of vehicle lower part closing plates, roughly rectangular vehicle lower part closing plates 2 and 2 are inserted into lower face opening receiving parts 1 and 1 of a vehicle body 10 from a vehicle exterior side, brought into contact with end edges 11 and 16 of the lower face opening receiving parts from a vehicle interior side, and fixed to the end edges by fastening bolts 3 from the vehicle exterior side. The vehicle lower part closing plates 2 and 2 are plates divided in a longitudinal direction, and connected foldably upward or expandably/contractibly in the longitudinal direction on division boundaries 23 and 23. Ends 21 and 21 in the longitudinal direction in a state where the vehicle lower part closing plates are folded or contracted can be inserted into the lower face opening receiving parts 1 and 1, and stop parts 13 and 14 covering the ends in the longitudinal direction in a stretched state are formed at base end reinforcing ribs 12 and 15 of the end edges.SELECTED DRAWING: Figure 2
【課題】両用下部ふさぎ板を車体の下面開口受部に挿入して所定の位置に配置した段階で、新たな操作を必要とすることなく、下面開口受部から車両用下部ふさぎ板が脱落するのを防止できる車両用下部ふさぎ板の脱落防止構造を提供する。【解決手段】略矩形状の車両用下部ふさぎ板2、2を車体10の下面開口受部1、1に車外側から挿入して下面開口受部の端縁部11、16に車内側から当接させ、車外側からボルト3を締結して端縁部に固定する車両用下部ふさぎ板の脱落防止構造であって、車両用下部ふさぎ板2、2は、長手方向で分割し、分割境界23、23にて上方へ折り曲げ可能に又は長手方向へ伸縮可能に連結したこと、下面開口受部1、1には、車両用下部ふさぎ板の折り曲げ状態又は収縮状態における長手方向端部21、21を挿入でき、伸長状態における長手方向端部を覆う止め部13、14を端縁部の基端補強リブ12、15に形成したことを特徴とする。【選択図】図2
