<p>Provided are a gasholder sealing material and gasholder sealing structure for which flex resistance at the low temperatures of cold regions can be improved while maintaining excellent airtightness. The gasholder sealing material (5) has a cylindrical form and is interposed between the inner circumferential surface of a tank (1) that configures a gas holder and the outer edge of a shock-absorbing member (3) that rises and falls inside the tank (1) in conjunction with a mobile lid (2), which rises and falls inside the tank (1), near the outer circumference of the mobile lid (2). The sealing material is configured so that, of the tank end (7), which is the side that is fixed to the inner circumferential surface of the tank (1), and the shock-absorbing member end (8), which is the side fixed to the outer edge of the shock-absorbing member (3), both surfaces of at least the tank end (7) are covered with ethylene propylene diene rubber and the portions other than the tank end (7) and the shock-absorbing member end (8) are not covered with ethylene propylene diene rubber.</p> |
