PROBLEM TO BE SOLVED: To provide a vibration-sensitive article fall prevention device that can reliably prevent fall of articles against the swing such as earthquakes.SOLUTION: A vibration-sensitive article fall prevention device includes: a stopper member 6 liftable between an upper position and a predetermined position capable of carrying in and out an article 15, on at least a tray 5 in the vertical direction of the tray 5, and provided so as to inhibit fall of the article 15 on the tray 5 in the predetermined position; a supporting part 20 for regulating the movement to the predetermined position in the stopper member 6, and enabling release of the regulation; and a pendulum member 30 including a vibration-sensitive moving part 32 for moving in the fore-and-aft direction of the shelf in response to the swing of the shelf and a regulation releasing member for releasing the regulation in the supporting part 20 with the movement of the vibration-sensitive moving part 32. The supporting part 20 is configured such that the supporting part 20 may be bent or twisted by the collision force of the regulation releasing member applied from a specific direction to the vector X of the moving force given to the stopper member 6. |
