[Problems to be solved by the device]

 In such a prior art, as shown in an enlarged view in FIG. 8, the inner diameter of the fitting groove 6 (the subscripts a and b are omitted in the generic name) is slightly smaller than the outer diameter of the fitting protrusion 8. When the displacement of each of the skeletons 1a and 1b is rapid and the displacement amount is large, a large force acts on the fitting protrusion 8 and the fitting groove 6 is removed. There is a problem that it is easily extracted. Further, since the fitting groove 6 and the fitting projection 8 extend along the direction perpendicular to the paper surface of FIG. 7, the central axis G1 of the fitting groove 6 and the central axis G2 of the fitting projection 8 are displaced from each other. If such a portion is formed, the fitting protrusion 8 cannot be smoothly rotated in the fitting groove 6, and therefore, when the respective skeletons 1a and 1b are displaced, the edge member 4 and the rotation member 7 are formed. There is a problem that a large force acts on the to deform or damage it.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide an expansion joint device capable of smoothly rotating the rotating member according to the displacement of each skeleton to allow the displacement. It is to provide a mounting structure for a cover body.
