A free access floor structure to install a manufacturing apparatus such as a semiconductor manufacturing apparatus, in a short time, and a manufacturing apparatus and a carrier apparatus adapted for the floor structure. An embodiment of the manufacturing apparatus includes an apparatus-side connector which is provided, facing downward, to a bottom plate of a manufacturing apparatus. A floor structure of an embodiment includes a floor plate to be worked into a floor surface. The floor structure includes a floor-side connector which is provided, facing upward, to the floor plate so as to be connected with the apparatus-side connector according to a lowering operation of the manufacturing apparatus. An installation step (mounting step, piping/wiring step) of the manufacturing apparatus may thereby be performed in one step. As a result, the labor and the time required to install the manufacturing apparatus may be saved.
