To provide a fall prevention device of a simple structure having an openable/closable net member.SOLUTION: A fall prevention device 1 is fitted to a water passage 5 being a recessed groove-shaped structure opened upward, and has a net member 2 and a locking tool 4 fitted to the water passage 5 and locking the net member 2. The locking tool 4 has a fixing part and an anti-loosening part, the fixing part is fixed to the second upper face part 55 of a sidewall of the water passage 5. The fixing part is positioned nearer to an opening side than to the anti-loosening part. A space is formed between the second upper face part 55 and the anti-loosening part, and the net member 2 is openably/closably fitted to the water passage 5.SELECTED DRAWING: Figure 1
【課題】開閉可能なネット部材を備える簡易な構造の転落防止装置を提供することを目的とする。【解決手段】上方が開口した凹溝状の構造物である水路５に取り付ける転落防止装置１であって、ネット部材２と、水路５に取り付けられ、ネット部材２を係止する係止具４と、を備え、係止具４は、固定部と抜止部を有し、固定部は、水路５の側壁の第２の上面部５５に固定され、固定部が抜止部よりも開口側に位置し、第２の上面部５５と抜止部の間に間隙が形成されることで、ネット部材２を開閉可能に水路５に取り付ける。【選択図】図１
