<P>PROBLEM TO BE SOLVED: To obtain a joint device for a floor capable of surely preventing a danger by forming an opening between both side walls of left-right building frames even when the left-right building frames are rocked in the different longitudinal directions and capable of being safely used. Ž<P>SOLUTION: The joint device for the floor is composed of an upper joint device using a joint plate capable of absorbing the rocking of a joint section between the left-right building frames with both side walls in a superposing form even when the left-right building frames are rocked in the different longitudinal directions. The joint device for the floor is further composed of a first end joint device using an extensible plate by abutting a front end section fitted at the lower place of the upper joint device on both side wall sides of one joint building frame capable of covering the opening formed to the side wall sections of the right and left building frames movably in the longitudinal direction of the other building frame at all times when the right and left building frames are rocked in the different longitudinal directions. The joint device for the floor is further composed of a second end joint device using the extensible plate abutting the front end section fitted at the lower place of the first end joint device on both side wall sides of the other joint side building frame movably in the longitudinal direction at all times to one joint side building frame.
