To provide a fall prevention device which prevents a person from falling in a gap part between a vehicle and a platform, utilizing a low-cost simple structure free from a large scale reform work.SOLUTION: A fall prevention device 6 prevents a fall in a gap part Δ between a vehicle 2 and a platform 5. An expansion and contraction part 7 changes from a contraction state to an expansion state to close the gap part Δ. The expansion and contraction part 7 expands from the platform 5 side to the vehicle 2 side during a period for getting on and off the vehicle 2 and contracts from the vehicle 2 side to platform 5 side except during the period for getting on and off the vehicle 2. A rotation step part 10 rotates to close the gap part Δ when the expansion and contraction part 7 changes from the contraction state to the expansion state. The rotation step part 10 changes from an open state to a close state by a push up force generated by the expansion and contraction part 7 when the expansion and contraction part 7 changes from the contraction state to the expansion state and changes from the close state to the open state because the push up force of the expansion and contraction part 7 is not generated when the expansion and contraction part 7 changes from the expansion state to the contraction state.SELECTED DRAWING: Figure 1

    【課題】大規模な改修工事が不要であり安価で簡単な構造によって車両とホームとの間の間隙部への転落を防止する転落防止装置を提供する。【解決手段】転落防止装置6は、車両2とホーム5との間の間隙部Δへの転落を防止する。膨張収縮部7は、間隙部Δを塞ぐように収縮状態から膨張状態に変化する。膨張収縮部7は、車両2の乗降時にはホーム5側から車両2側に膨張し、車両2の乗降時以外には車両2側からホーム5側に収縮する。回転ステップ部10は、膨張収縮部7が収縮状態から膨張状態に変化したときに、間隙部Δを塞ぐように回転する。回転ステップ部10は、膨張収縮部7が収縮状態から膨張状態に変化したときに、この膨張収縮部7から押上力が作用して開状態から閉状態に変化し、膨張収縮部7が膨張状態から収縮状態に変化したときに、この膨張収縮部7から押上力が作用せず閉状態から開状態に変化する。【選択図】図1
