PROBLEM TO BE SOLVED: To suppress damage of a stopper, a guide roller, a piston truss or the like; to prevent tilt of a piston; and to avoid damage of a gas holder.SOLUTION: A gas holder includes a holder body which has a side wall supported by a plurality of erected columns 112 and stores gas in a space surrounded by the side wall, a piston lifting and lowering in the holder body, a guide roller 172 rolled to the column in accordance with lifting and lowering of the piston, a pressurizing mechanism 180 for applying a load PF to the column through the guide roller, a regulating mechanism for regulating movement of the guide roller when a load larger than the load PF and less than a threshold is applied from the column to the guide roller, and a displacement absorbing mechanism 200 which releases regulation of the guide roller by the regulating mechanism and absorbs the displacement of the guide roller to the piston when a load equal to or more than the threshold is applied from the column to the guide roller.SELECTED DRAWING: Figure 5 |
