<p>In the present invention, the vibrations of a rack are damped without dependence on natural-frequency differences. Said rack (4, 5) is provided along the travel space of a loading/unloading device in an automated warehouse. The rack (4, 5) comprises structural units each provided with the following: a front support column (6), on the travel-space side; a rear support column (7), at a separation from the travel space; and a tension brace (14) and damper (16) that diagonally connect the front support column (6) and the rear support column (7) and cross each other. Two types of said structural unit are provided, with the tension brace (14) and damper (16) in opposite positions.</p> |
