OPENING AND CLOSING ROOF

PURPOSE:To shorten the time necessary for opening and closing by providing a crescent-shaped fixed roof on one end of a circular doom roof, and forming a triangular rotating moving roof and a running moving roof on the other end. CONSTITUTION:A fixed roof 3 is formed into a crescent-shape so that the top space of an outer wall 2 is covered therewith. A triangular area in the outer circumferential direction of the fixed roof 3 from a rotating point 6 is covered with a rotating moving roof 4, and the remaining is covered with a running moving roof 5. While the rotating shaft 11 of the rotating moving roof 4 is moved integrally with the running moving roof 5, a truck 13a is linearly moved on a rail. Further, the rotating moving roof 4 is turned together with the moving roof 5 while rotating with the rotating shaft 11 as the center to integrally open the moving roof 5. Hence, as the moving roof has a piled structure, the structure of the frame can be simplified.
