Abstract:
To provide a stone structure capable of rotatably supporting the main body stone without the shaft rod penetrating the main body stone while preventing the base stone from falling off from the main body stone.SOLUTION: A stone structure 1 includes a base stone 10, a main body stone 20, and a support portion that rotatably supports the main body stone 20 so that the central axis of rotation extends in the vertical direction above the base stone 10. The main body stone 20 has a bottomed and columnar hole that opens at the lower end surface. The support portion includes a shaft rod 30 and a flat plate 40. The flat plate 40 is fixed to the lower end surface of the main body stone 20 so as to close a part of the opening of the hole and open the other part of the opening of the hole. The shaft rod 30 has a first diameter portion 31 having a first diameter substantially the same as diameter of the hole and being rotatably housed in the hole, and a second diameter portion 32 having a second diameter smaller than the first diameter and projecting vertically downward from the first diameter portion so as to pass through the flat plate 40 through the other part, and the lower end portion is fixed to the base stone 10.SELECTED DRAWING: Figure 6
