ている。Conventional technology and its problems In general, sealed lead-acid batteries have a sealed structure consisting of a battery case that opens upward and a lid that covers the top of the battery case, and the inside of the battery is divided by a partition wall into several cells. A chamber is formed. Inside each cell room is shade, Ii! An electrode plate group consisting of a plurality of electrode plates and separators stacked one on top of the other is inserted under a load (pressure), and the lid is provided with an exhaust valve.

素ガスが負極板と反応（Ｐｂ−１’ＡＯ２→ｐｂｏ ）
する。When the sealed lead-acid battery is charged, the internal pressure of the battery increases due to gas generation. Particularly during overcharging, the internal pressure of the battery increases significantly. Normally, when the internal pressure of the battery rises to a predetermined pressure, the generated gas is exhausted to the outside of the battery from the exhaust valve. However, when the battery is left alone, the oxygen gas accumulated inside the battery reacts with the negative electrode plate (Pb-1'AO2→pbo).

う欠点があった。Furthermore, it reacts with the electrolyte (PbO+ n2so4→PbSO4
+H20), oxygen gas is consumed, and the internal pressure of the battery becomes negative with respect to the outside air. When the internal pressure of the battery becomes negative, the short side of the battery case appears to be depressed. If left in this state, the electrode plate group will be compressed, and as a result, the entire separator will be FE-shrinked. When the battery is then charged and the internal pressure of the battery rises, the battery case expands, but the compressed separator hardly recovers. When this state occurs, [t*,! = [
Since gaps are formed between the plate details, the tension applied to the electrode plate group is almost eliminated, resulting in a disadvantage that the vibration resistance of the battery deteriorates.

類の体積膨縮体１６が配置されている。The sealed lead-acid battery 1 of the present invention includes a monoblock type battery case 2 that opens upward, and a lid 6I that covers the top of the battery case 2! 1.
The lid 6 is provided with an exhaust valve 4 that releases gas to the outside of the battery when the inside of the battery reaches a predetermined pressure. The exhaust valve 4 is arranged so as to cover the valve hole 5 and is fixed by a holding plate 6. 7 is a gas exhaust groove, which communicates with the atmosphere. The interior of the sealed lead-acid battery 1 is divided by partition walls 8 to form a plurality of cell chambers 9. In each cell chamber 9, a group of electrode plates is inserted, in which several positive and negative plates 10 and seven pallets 11 made of fine glass fibers are stacked one on top of the other. Note that the electrolyte is substantially held by the positive and negative electrode plates 10 and the separator 11, making the sealed lead acid battery 1 body-free. Further, in the battery case space above the electrode plate group of each cell chamber 9, a volume expansion/contraction body 16 made of polypropylene is arranged, one end of which communicates with the atmosphere through an atmosphere communication hole 12.

た。また、体積膨縮体１３０体積は、極板群上の電槽空
間部容積の約し７に設定した。The volume expansion/contraction body 13 was manufactured by processing a box-like polypropylene box having a thickness of 0.8 fins by heat sealing the seams. Further, the volume of the volume expansion/contraction body 130 was set to approximately 7 times the volume of the battery case space above the electrode plate group.

The investigation was carried out by changing the air pressure inside the volume expansion/contraction body 13 from the atmosphere communication hole 12 and measuring the SA dimension. As a result, atmospheric pressure +0.28~0

。Next, the following comparative test was conducted using the sealed lead acid battery of the present invention (product of the present invention) and the conventional sealed lead acid battery (conventional product), each using 5Wi. Both the inventive product and the conventional product are 28A
h15HR (12V), and the conventional product is the volume expansion and contraction body 1.
The product is the same as the product of the present invention except that it does not include the item 3.

After standing for a period of time, the three dimensions shown in FIG. 2 were measured. The results are shown in Table 1.

ル室９内が負圧になると体積膨縮体１６が膨張し、大気
圧と電池内圧とがバランスするためである。As is clear from Table 1 of the margin m1 table below, the product of the present invention does not cause dents on the short side of the container when left unused. This is because, as shown in FIG. 3, when the inside of the cell chamber 9 becomes negative pressure, the volume expansion/contraction body 16 expands, and the atmospheric pressure and the battery internal pressure are balanced.
次に上記電池を用いて、完全充電後、更に５０％の過充
電を行なった後に同様に３寸法を測定した。その結果を
第２表に示す。Next, using the above battery, after being fully charged and further overcharging by 50%, three dimensions were similarly measured. The results are shown in Table 2.

槽短側面のふくれを防止することができる。Table 2 As is clear from Table 2, there was not much difference in the three dimensions between the product of the present invention and the conventional product. This is because even if the battery internal pressure increases due to overcharging, the exhaust valve 4 acts to lower the battery internal pressure. However, in the product of the present invention, even if the variation in the opening pressure of the exhaust valve 4 is larger than the change in the atmospheric pressure of the body yi expansion/contraction body 13, as shown in FIG. The volume expansion/contraction body 13 absorbs this by shrinking, and can prevent the short side of the battery case from blistering.
