<p>PROBLEM TO BE SOLVED: To provide a vibration-sensitive article fall prevention device capable of surely preventing an article from falling with vibration by an earthquake or the like.SOLUTION: There are included: a stopper member 6 capable of descending between an upper position and a prescribed position which do not influence taking in and out at least an article on a shelf stage in the vertical direction of a shelf stage 5, and provided so as to inhibit the article on the shelf stage from falling in the prescribed position; a support part 20 fixedly supporting the stopper member 6 on a vector X of a moving force given to the stopper member 6, regulating the movement of the stopper member 6, and releasing the regulation by bending or inflecting; and vibration-sensitive actuation means 3 including a vibration-sensitive movement part 30 reacting with the vibration of a shelf 2 and moving to the front/back direction of the shelf 2, and a regulation releasing part 32a for releasing regulation in the support part 20 with the movement of the vibration-sensitive movement part 30. The vibration-sensitive actuation means 3 is so formed as not to release regulation in the support part 20 by the regulation releasing part 32a when the vibration-sensitive movement part 30 moves to the front/back direction of the shelf 2.</p> |
