In addition, with the configuration according to the third aspect, when the transporting device is located in the traveling passage formed between the storage shelves, an earthquake or the like occurs and the installation location of the storage shelves is changed. Vibration, when the vibration detection means detects the vibration equal to or greater than the setting, the shelf drive means moves the storage shelf in a direction away from the transport device, while the transport device is located outside the traveling path, When the vibration detecting means detects the vibration exceeding the setting, the shelf driving means allows the storage shelf to move freely. In other words, when the location of the storage shelves vibrates due to an earthquake or the like, the state in which the movement of the storage shelves is restricted is reduced as much as possible, and while preventing the transfer device from being damaged as much as possible. The vibration of the storage shelf itself can be suppressed as much as possible.

In addition, with the configuration of the fourth aspect, the shelf driving means exerts a movement driving force at the lower end of the storage shelf, and the storage shelf is guided at both upper and lower ends by the guide rails. In this state, it moves by the movement driving force of the shelf driving means. That is, the storage shelf moves stably due to the movement driving force acting on the lower end. In such a configuration, since the upper and lower ends of the storage shelf are guided by the guide rails, an earthquake or the like may occur. When the installation location of the storage shelf vibrates, the storage shelf is driven by the movement driving force of the shelf drive means to move the entire storage shelf in a direction away from the transport device, and the force acting on the transport device is allowed. It can be reduced as much as possible.
