。The lifting mechanism for lifting and unloading cargo by moving the loading platform up and down has a casing that moves up and down together with the loading platform, and within this casing there is a roller that rotates as the loading platform moves up and down, and a rotatable roller. A locking lever is pivotally supported, and a roller is attached to the locking lever at a position offset from the shaft support [7, and an endless belt is wound around with a tension roller interposed between each of the rollers, 5. A fall prevention device for a lifting mechanism such as a lifter, characterized in that when the loading platform falls, the locking lever is frictionally locked to a fixed support such as a force guide bar when the locking lever is rotated by the tension of the endless belt. .
