A metal reinforcing plate (3) is welded in place close to the opening on the inside of the battery case (1), and a plastic insulation gasket (2) and a sealing member (5) provided with an anti-explosion mechanism or the like are sequentially mounted on the metal reinforcing plate (3). By this arrangement, higher battery capacity can be realized by eliminating the waste of space because it is unnecessary to form a conventional indentation around the upper wall of a battery case (1) in the conventional manner. A sealed battery construction having an anti-explosion mechanism and being highly reliable in terms of leakage prevention can be thereby obtained. <IMAGE> |
