The half-moon-shaped roof members located at both ends are swiveling roofs that move in the circumferential direction of the opening, and the other center-side roof member pivotally supports one end at one end, and turns around this pivot point. Since the movable roofs are movable and move horizontally, each support point for guiding movement is at a horizontal level and can be stably and safely supported. is there. In addition, since the swiveling roof only moves along the circumferential direction of the opening, and the swiveling roof only swivels around the swiveling axis, each movement is a separate movement and interferes with each other. In order to avoid such a situation, each can be freely opened and closed, and a free stop position can be selected. This allows a free aperture ratio to be selected, and it is also possible to adjust the spectator seat and the ground surface so as not to be dazzling according to the incident direction of sunlight. Further, since each of the rotating roof and the swiveling roof simply performs a swiveling or swiveling motion, the guiding direction is extremely simple, and there is an effect that the construction of the guide rail structure and the attaching direction thereof are simplified. .
