Abstract
In an openable roof apparatus for a space, a first and a second movable roof structures have their respective both ends which are supported respectively by a pair of stationary support structures for movement therealong. A pair of guide arrangements are arranged respectively on the pair of stationary support structures. The first and second movable roof structures are movable toward and away from each other along the guide arrangements. The first movable roof structure includes a plurality of movavble roof units having their respective axes which extend perpendicularly to the guide arrangements. The first and second movable roof structures are movable between a closed position where the movable roof units of the first movable roof structure cooperate with the second movable roof structure to close the space, and an open position where the movable roof units of the first movable roof structure are moved away from the second movable roof structure to open the space. In the open position, the movable roof units of the first movable roof structure are overlapped with each other.
