    Abstract: PROBLEM TO BE SOLVED: To provide a bridge fall preventing device with a displacement limiting function for a bridge by which the device as a whole is made compact, the construction cost is reduced, and the appearance is prevented from being spoiled.
    SOLUTION: The bridge fall preventing device 1 with the displacement limiting function for the bridge includes a displacement limiting mechanism comprising a first member 8, a second member 14, and a displacement limiting plate 19. The first member 8 arranged on either an upper structure 2 or a lower structure 3 has a long hole 11 extending in the direction of a bride axis. The second member 14 is arranged on the other one of the upper structure 2 and the lower structure 3, and is provided with a pin 15 having an end penetrating the long hole 11 and relatively movable along the long hole 11. A lift force stopping member 17 having a diameter larger than the width of the long hole 11 is fixed to the end of the pin 15 penetrating the long hole 11. The displacement limiting plate 19 has a relatively movable distance between the first member 8 and the second member 14, which is shorter than the relatively movable distance corresponding to the length of the long hole in the direction of the bridge axis. When stress is loaded by horizontal displacement exceeding a predetermined value, the relatively movable distance in the direction of the bridge axis is increased.
