PROBLEM TO BE SOLVED: To provide a joint device for a floor capable of absorbing shakes even if right and left floor skeletons are unevenly settled due to an earthquake and also even if a joint part becomes wider or narrower, and capable of safely traveling on a joint cover by assuredly supporting the joint cover.SOLUTION: The joint device for a floor includes: a plurality of extendable joint cover support mechanisms whose both ends are attached to floor skeletons on a joint part side of the right and left floor skeletons at predetermined intervals; and a joint cover device which is attached while being supported by the plurality of joint cover support mechanisms and at least 2 or more tips of which are overlapped each other. The plurality of joint cover support mechanisms constitute one support arm, the other support arm, and a central support arm slidably engaged with the other support arm and the one support arm. |
