An air spring device (10) comprises a top surface panel (12); a bottom surface panel (14) disposed opposing the top surface panel (12); and a flexible film body (16) that elastically couples the top surface panel (12) and the bottom surface panel (14), and forms a pressurized space (18) between the top surface panel (12) and the bottom surface panel (14). The top surface panel (12) and the bottom surface panel (14) have mutually opposing flat parts (42) and (44), respectively. The flat part (44) of the bottom surface panel (14) (one surface panel) is formed to have a larger surface area than that of the flat part (42) of the top surface panel (12) (the other surface panel). On the bottom surface panel (14) (the one surface panel), provided is a restriction part (50) formed so as to approach the top surface panel (12) (the other surface panel) moving away from the center of the one flat part (44) with the outer edge of the one flat part (44) as a starting end. |
