PROBLEM TO BE SOLVED: To provide a shelf assembly structure capable of positively and stably erecting a ceramic rod for preventing falling of an object to be calcined in an end of a shelf board, even when the shelf board is thinned. SOLUTION: A hollow holder 5 integrated with the shelf board 2 is provided on the end of the shelf board 2, and a lower part of the ceramic rod 4 for preventing falling of the object to be calcined is inserted and held in the hollow holder 5. A vertical hole is provided in an upper end part of a strut 3, a through hole or a cutout corresponding to the vertical hole is provided in the end of the shelf board 2, and the lower part of the ceramic rod 4 is inserted and held in the vertical hole of the strut via the through hole or the cutout. The ceramic rod 4 can be positively erected even when the shelf board 2 is thinned, and an energy saving effect of 5-10% can be provided. COPYRIGHT: (C)2007,JPO&INPIT
