To provide a runaway prevention device capable of preventing a rail travel-type machine from running away while suppressing an installation cost rise of the rail travel-type machine.SOLUTION: A runaway prevention device 10 comprises a pair of fixing metal fitting 12, an insert metal fitting 14 provided on a rail 3, and a first receiving metal fitting 16 provided on the rail 3 between a wheel 8 and the insert metal fitting 14. A supporting surface 30a to support the insert metal fitting 14 and a first wall surface 30b extending upward from an end of the supporting surface 30a are formed on the fixing metal fitting 12. The movement of the insert metal fitting 14 to one side in the extending direction of the rail 3 is regulated by the first wall surface 30b, the movement of the first receiving metal fitting 16 to the one side is regulated by the insert metal fitting 14, and the movement of the wheel 8 in the one side is regulated by the first receiving metal fitting 16.SELECTED DRAWING: Figure 5

    【課題】軌条走行式機械の設置コストの上昇を抑制しつつ、軌条走行式機械の逸走を防止できる逸走防止装置を提供する。【解決手段】逸走防止装置10は、一対の固定金物12と、レール3上に設けられる挿入金物14と、レール3上において、車輪8と挿入金物14との間に設けられる第1受け金物16と、を備える。固定金物12には、挿入金物14を支持する支持面30aおよび支持面30aの端部から上方に延びる第1壁面30bが形成されている。レール3の延伸方向における一方側への挿入金物14の移動は第1壁面30bによって規制され、第1受け金物16の前記一方側への移動は挿入金物14によって規制され、車輪8の前記一方側への移動は第1受け金物16によって規制される。【選択図】 図5
