(Effects of the Invention) As described below, according to the present invention, when the two skeletons of a building adjacent to each other with a predetermined gap therebetween are relatively displaced, the holder member receives the elastic force of the elastic body. By sliding or tilting in this state, the relative displacement can be dealt with, so that an accident in which the cover member is twisted or damaged can be prevented.

In particular, the skeleton abutting portion of the flexible sealing member attached to the roof skeleton side supporting member is brought into contact with the skeleton surface of the roof skeleton, and the cover abutting portion of the sealing member is abutted against the back surface of the cover member. By doing so, airtightness and watertightness can be reliably maintained from the body surface of the roof body to the back surface of the cover member. Furthermore, the gap between the body surface of the roof body and the back surface of the cover member can be surely closed by the flexibility of the seal member even when both the bodies are changed,
It is possible to positively prevent the trouble that rainwater enters with the wind.
