PROBLEM TO BE SOLVED: To obtain durability having strong and high load in a folding plate bearing device capable of sliding part thereof so as to prevent the occurrence of distortion in the case where a fixed folding plate is expansible by heat. SOLUTION: A folding plate bearing device 1 is so constituted that a locking member 13 for locking a folding plate 3b is fixed to the upper part thereof. Then, an upper member 5 for fixing the locking member 13 is provided, the upper member 5 is mounted on a lower member 4 fixed on a roof decking material (underfelt roof 2) in a slidable manner in the longitudinal directions of folding plates 2b and 3b and, at the same time, a space between the lower member 4 and upper member 5 is positively connected with a joint device constituted of an engaging section 5d and a holding section 9 incapable of being separated in the vertical direction. |
