れたものであった。2. Description of the Related Art In recent years, sealed lead-acid batteries have been remarkably required to have high energy density and long life. However, the conventional clad-type lead-acid battery or the past-type lead-acid battery in which the active material is applied to the grid body made of a lead alloy has a limit in achieving both high energy density and long life. Therefore, attention is paid to the stacked lead-acid battery as one that satisfies this demand. As shown in FIG. 10, the conventional laminated lead-acid battery has a separator 18 made of a glass mat between a positive electrode plate and a negative electrode plate in which an active material layer 17 is coated on a metal sheet 16 for current collection. A pole group is formed, and reinforcing plates 19 are brought into contact with both sides of the pole group if necessary, and the entire both sides of the pole group with the reinforcing plate 19 are in the battery case 14
It was stored in the battery case 14 while being pressed by the lid 15.

にある。In the lead acid battery of FIG. 10, the pressing force of the pole group is maintained by the battery case 14 and the lid 15. Therefore, if the pole group becomes large, the pressing force of the pole group is maintained. Therefore, it is necessary to increase the thickness of the battery case 14 and the lid 15, and there is a problem in that the volume efficiency decreases as the battery size increases. The present invention has been made in view of the above problems, and an object thereof is to maintain the pressing force of the pole group without increasing the thickness of the battery case and the lid, that is, stacking excellent in volume efficiency.
