The second mode for carrying out the invention shown in FIGS. 11 to 13 is mainly different from the first mode for carrying out the invention in that a pantograph in which two substantially rectangular links are connected is used. In the point that the cover device 8A uses the link member 18A, the roof joint joint device 1A using the cover device 8A is similar to the first embodiment for carrying out the present invention. The effect can be obtained.

In addition, in the embodiment of the present invention, the cover plate is attached to the cover device by using the link member. However, for example, the cover plate is directly attached to the guide rail without using the link member, and the gap becomes narrow due to an earthquake. In this case, the cover plate at the lower end is pushed up by the drain cover, until the cover plate at the lower end contacts the cover plate at the center, and then the cover plate at the lower end presses the cover plate at the center. Then, the cover plate at the lower end portion and the cover plate at the central portion may be configured to move upward and absorb the shaking motion.

In addition, the cover plate may be attached using any configuration as long as a part (mainly the lower part) of the cover plate can be moved vertically and the gap can be constantly closed.

Furthermore, in the present embodiment, the case where three cover plates are used has been described, but two cover plates may be used, or four or more cover plates may be provided. When using two cover plates, attach only the lower cover plate so that it moves up and down.
