To provide a panel structure, by which a desired wall can be exchanged easily and which can take measures against the damage of the wall rapidly at low cost.

The panel structure has a plurality of supports 1 disposed upright on a base section 9, wall panels 2 arranged among these supports 1 and a beam section 3 bridging the mutual upper end sides of the supports 1, and vertical moving mechanisms 4 for vertically moving the supports 1 are installed to the supports 1 of the whole or a part in the supports 1. Openings 14 are formed among the wall panels 2 and the base section 9 or the beam section 3 under the state, in which the supports 1 placed on both end sides of the wall panels 2 to be exchanged are shifted upwards, at that time.
