PROBLEM TO BE SOLVED: To enhance earthquake resistance by interposing an earthquake-isolating means between a load supporting stand for supporting a load in a load storage space of a rack and supporting members which are projected from right and left bulkhead frames of the load storage space to support the load supporting stand. SOLUTION: An earthquake-isolating means comprises four earthquake-isolating units 8 which are arranged at the positions for supporting four corners of a load W to be stored in a load storage space 1 and supported by supporting members 7a, 7b. Each earthquake-isolating unit 8 comprises supporting pillars 16 erected from the supporting members 7a, 7b, a movable body 17 to be slidably supported by the supporting pillars 16 in every horizontal direction, and an urging member 19 which is interposed between an annular circumferential wall 18 continuously provided downwardly from the movable body 17 and the supporting pillars 16 to urge and hold the movable body 17 at the substantially center position in its slidable range. The four movable bodies 17 which are respectively slidable on the four earthquake-isolating units 8 are also used for a load supporting stand 32. COPYRIGHT: (C)2010,JPO&INPIT
