[0020]

As is clear from the above description, the following effects can be obtained in the present invention.

(1) A pair of recesses formed near the joints on the floors of the left and right buildings built via the joints so as to open to the joints, and fixed to the pair of recesses, respectively. A pair of fixing brackets whose inclined joint surfaces are inclined guide surfaces, a joint plate for covering a portion of the pair of fixing brackets excluding the guide surface, and fixed or lower side portions respectively at both ends of the joint plate. A protective body made of an elastic material such as rubber covering the guide surfaces of the pair of fixing brackets rotatably mounted on the pair of fixing brackets or the skeleton of a floor portion of the left and right buildings. Since the supporting rod attached to the central portion of the joint plate is constituted by at least two or more central maintaining devices pivotally supported so as to be able to move up and down, the size of the joint portion due to an earthquake or the like. If narrowed, it is possible to protect body formed of an elastic material at both end portions is projected onto the floor of the left and right of the building. Therefore, since the protruding distal end is a protective body made of an elastic material, safety can be ensured as compared with a conventional case in which a metal portion formed at an acute angle protrudes.

(2) According to the above (1), it is only necessary to attach the protectors to both ends of the joint plate, so that the joint plates can be easily attached.

(3) According to the above (1), the protection bodies at both ends of the joint plate are rotatably mounted, whereby the protection bodies are rotated, and the front ends of the protection bodies are moved to the floors of the left and right buildings or the floor. The slide can be slid while in contact with the guide surfaces of the pair of fixtures. Therefore, the opening at the time of the swinging movement becomes small, and it can be used more safely.

(4) Claims 2 and 3 are also the above (1) to (3).
The same effect can be obtained.
