PROBLEM TO BE SOLVED: To keep a support plate in a tilting attitude by a shelf board main body inserted into a groove of the plate, by constructing a shelf board out of the shelf board main body having a recessed or projecting part formed on one lateral side at least and having a slender section and of the support plate which is kept in the tilting attitude by inserting the shelf board main body slidably into the groove formed in the lower edge thereof and so shaped as to be matched with the shelf board main body and holds a tile substrate in the tilting attitude. SOLUTION: This shelf board for burning a flat plate tile is constructed of a shelf board main body 1 having a recessed part 2 or a projecting part formed on one lateral side at least and having a slender section and of a support plate 3 which is kept in a tilting attitude by inserting the shelf board main body 1 slidably into a groove 5 formed in the lower edge thereof and matched with the shelf board main body 1 and holds a tile substrate (a) in the tilting attitude. Since the support plate 3 is kept in the tilting attitude by inserting the shelf board main body 1 into the groove 5 thereof, in this case, a prop plate is dispensed with and an interval of the support plate 3 can be narrowed. Since this interval can be adjusted arbitrarily, moreover, the number of the tile substrates (a) which can be set on one shelf board main body can be increased at the maximum according to the shape of the tile substrate (a) and thus an effect of high burning efficiency is produced. |
