To provide a derailment/falling prevention device capable of preventing a machine and a facility from being damaged while preventing derailment and falling of the machine and capable of preventing floating of a wheel and overturning of the machine.SOLUTION: A derailment/falling prevention device of a machine travels with wheels. The derailment/falling prevention device 1 includes a contact member 12 that is arranged on a side of a traveling path of a wheel 3 and has a contact surface 12f being in contact with the traveling path of the wheel 3, a moving mechanism 15 connected to the contact member 12 to hold the contact member 12 so as to be moved forward and backward along a rotary shaft direction of the wheel 3, and a hook member 20 for hooking a first end part 20a to the traveling path of the wheel 3. The moving mechanism 15 includes an absorbing part 16 for absorbing a force in the direction of moving backward of the contact member 12. The hook member 20 is arranged such that the first end part 21a protrudes from the contact surface 12f when the contact member 12 is moved backward.SELECTED DRAWING: Figure 1

    【課題】脱輪や機械の落下を防止しつつ機械や設備の損傷を防止でき、しかも車輪の浮き上がりや機械を転倒も防止できる脱輪・落下防止装置を提供する。【解決手段】車輪によって走行する機械の脱輪・落下防止装置であって、脱輪・落下防止装置1が、車輪3の走行径路の側方に配置された、車輪3の走行径路と接触する接触面12fを有する接触部材12と、接触部材12に連結され車輪3の回転軸方向に沿って接触部材12を進退可能に保持する移動機構15と、第一端部20aを車輪3の走行径路に引っ掛ける引っ掛け部材20と、を備えており、移動機構15は、接触部材12が後退する方向の力を吸収する吸収部16を有しており、引っ掛け部材20は、接触部材12が後退すると第一端部21aが接触面12fよりも突出するように配設されている。【選択図】図1
