Then, the moving carriage 24 travels along the rail 30 by rotating the wheel 26 by the motor to roll on the rail 30.

  With such a configuration, the roof portion 16 is supported by the upper end surface 28 of the outer peripheral wall 20 via the movable carriage 24 and the rail 30, and rotates horizontally by causing the movable carriage 24 to travel along the rail 30. That is, the roof portion 16 rotates horizontally by the traveling of the movable carriage 24 that receives a vertical load that acts on the ring portion (the skirt portion 22) constituting the outer periphery of the lower end portion of the roof portion 16.

  The facility 12 is a soccer stadium, and as shown in the plan view of FIG. 3, the facility 12 is provided with a soccer court 32 and stands 34, 36, 38, 40 equipped with a number of bleachers. ing. Natural grass is laid on the entire area of the competition area A formed by the area A1 of the soccer court 32 and the area A2 around the soccer court 32.

  The stand 34 is arranged so as to surround the entire circumference of the competition area A, and the stand 36 is arranged so as to surround the entire circumference of the stand 34. In addition, movable stands 38 and 40 are disposed opposite to each other inside the stand 34 so that the soccer court 32 is disposed therebetween.

  Further, a part of the stand 36 located behind the stand 38 is a main stand 36A, and a part of the stand 36 located behind the stand 40 is a back stand 36B.

  As shown in the plan view of FIG. 4, an opening 42 as a daylighting portion is formed in an elliptical shape in the roof portion 16 asymmetrically with respect to the rotation center M of the roof portion 16. The opening 42 has a size including the rotation center M, and light is taken from the outside of the roof portion 16 to the inside (facility 12 side) through the opening 42. In FIG. 4, for convenience of explanation, the rotation center M is drawn with a black dot, but a rotation support member such as a support does not exist at the rotation center M.

  Next, the operation and effect of the building including the rotary roof according to the embodiment of the present invention will be described.

  In the building 10 of the present embodiment, as shown in FIG. 1, the opening 42 is moved by rotating the roof 16, and the position irradiated with light from the opening 42 is changed, so that the outside of the roof 16. Thus, it is possible to irradiate light to a necessary area of the facility 12 and collect the light. That is, it is possible to perform daylighting on an area shielded by the roof without using a complicated roof structure.

  For example, in the plan view of FIG. 5, the roof 16 is rotated and set so that the soccer court 32, the stand 40, and the back stand 36 </ b> B are arranged to be opened to the outside of the building 10 through the opening 42. The state is shown.

  When the game is being held on the soccer court 32, if the roof 16 is arranged in this manner, the soccer court 32 can be brightly illuminated by sunlight during the daytime. Can be fed into the soccer court 32 from the opening 42. Further, for the main stand 36 </ b> A and a part of the stands 34, 36 that are covered with the roof portion 16 (the portion where the opening portion 42 is not formed), the roof portion 16 serves as a rain shield or an awning.

  Further, for example, the plan view of FIG. 6 shows a state in which the roof portion 16 is rotated and set so that the opening 42 is arranged in the south direction. The letter “N” depicted in FIG. 6 indicates the north direction.
