詳細図である。In the manufacture of such a conventional sealed lead-acid battery, after the electrode plate group 3 is housed in the battery case 1 and the cells are connected to each other, the lid 2 is joined and a fixed amount from the exhaust tube 4 is applied. The first charge is performed by injecting diluted sulfuric acid of. Immediately after the end of the first charge, residual gas is generated from the electrode plate group 3. Therefore, even if the rubber valve 5 is attached, the pressure inside the cell rises and the rubber valve is not pressed,
The rubber valve will fly away. Therefore, it is easy to work the rubber valve after the residual gas is generated for several tens of minutes. If the rubber valve is not fitted, air will enter the cell through the exhaust pipe 4 and oxidize the negative electrode, so it is necessary to complete the rubber valve fitting work within about 2 hours. As described above, the conventional method of welding and adhering the rubber valve pressing plate 6 takes a lot of time and is a bottleneck in production, although there is a time constraint. FIG. 2 is a detailed view of the valve portion.
