PROBLEM TO BE SOLVED: To provide a structure for preventing falling of a vehicle lower part closing plate, 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 are brought into contact with lower face opening receiving parts 1 and 1 disposed at a position where the vehicle lower part closing plates face each other with a lower face opening part 9 of a vehicle body 10 disposed between them from a vehicle interior side, and the vehicle lower part closing plates 2 are detachably fixed to the lower face opening receiving parts 1 and 1 by fastening bolts 3 from a vehicle exterior side. On the lower face opening receiving parts, at least a pair of flange engaging pins 51 and 52 are provided so as to project toward the vehicle interior side, and a plunger pin 4 having a lock nail 41 projecting on the vehicle interior side and energized on the vehicle interior side by an elastic body 46 is provided.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を車体10の下面開口部9を隔てて対向する位置に設けた下面開口受部1、1に車内側から当接させ、車外側からボルト3を締結して車両用下部ふさぎ板2を下面開口受部1、1に着脱可能に固定する車両用下部ふさぎ板の脱落防止構造である。下面開口受部には、少なくとも一対の鍔付き係止ピン51、52を車内側へ突出して設けるとともに、車内側に突出した係止爪41を有し弾性体46によって車内側へ付勢されるプランジャピン4を設けた。【選択図】図1
