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: Roughly rectangular vehicle lower part closing plates 2 are brought into contact with lower face opening receiving parts 1 from a vehicle interior side, and fixed to the lower face opening receiving parts by fastening bolts 3 from a vehicle exterior side. The lower face opening receiving parts are arranged at a position where the lower face opening receiving parts face each other in a vehicle longitudinal direction with a lower face opening part between them, and on the lower face opening receiving parts, flange engaging pins 51 and 52 are erected by facing each other in the vehicle longitudinal direction. On the vehicle lower part closing plates, a notch part 61 engaged with the engaging pin 51 erected on one lower face opening receiving part is formed, and a hole part 62 engaged with the flange engaging pin 52 erected on the other lower face opening receiving part is formed. On the lower face opening receiving parts or the vehicle lower part closing plates, is provided an energizing member 71 for energizing the flange engaging pins, the notch part and the hole part in a direction in which they are engaged with one another.SELECTED DRAWING: Figure 1
【課題】車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せず、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。【解決手段】略矩形状の車両用下部ふさぎ板2を下面開口受部1に車内側から当接させ、車外側からボルト3を締結して下面開口受部に固定する。下面開口受部は、下面開口部を隔てて車両前後方向で対向する位置に配置し、下面開口受部には、鍔付き係止ピン51、52を車両前後方向で対向してそれぞれ立設し、車両用下部ふさぎ板には、一方の下面開口受部に立設した鍔付き係止ピン51と係合する切欠き部61を形成し、他方の下面開口受部に立設した鍔付き係止ピン52と係合する孔部62を形成し、下面開口受部又は車両用下部ふさぎ板には、鍔付き係止ピンと切欠き部及び孔部とをそれぞれ係合させる方向へ付勢する付勢部材71を設けた。【選択図】図1
