PURPOSE: To save a containing space and obtain a variable shape opening part, by making it possible to contain the central roof in the upper part of the fixed roof when opening the opening part and also to rotate the central roof and the side roof in the circumferential direction.
CONSTITUTION: An opening part 10a is opened and contained in the upper part of a fixed roof 10 from the top of the opening part 10a. And the central roof 11a, 11a is rotated in the circumferential direction of the fixed roof 10 at the upper part of the fixed roof 10. On the other hand, the side roofs 11b, 11b is rotated only in the circumferential direction of the fixed roof 10 along the periphery of the opening part 10a. Respective roofs 11a, 11a, 11b, 11b are mounted on the respectiver trucks 15 to move them. The truck 15 travels on the rails 20 laid on the upper face of the fixed roof 10. In this structure, it is not necessary to keep the containing space for the movable roof at the side of the building.
