PROBLEM TO BE SOLVED: To obtain a joint device for a floor, which enables a floor decorating material such as a stone, a tile and a brick to be neatly stuck on the whole top surface of a joint plate, and which enables costs to be reduced by wholly using the relatively thin joint plate. SOLUTION: This joint device for the floor makes the floor decorating material fixed to the top surface of a shallow pan-like joint plate body, and uses the joint plate which has a back end locked by a supporting pin. In the joint device for the floor, a supporting protrusive piece formed by protruding a bottom surface of the back end of the joint plate downward is formed; and a supporting pin case, in which the supporting pin fixed to a joint plate supporting recess is supported in such a manner that the leading end of the joint plate can be turned upward, is provided in the region of the supporting protrusive piece.
