し、特にその安全弁の改良に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealed lead-acid battery, and more particularly to an improvement in a safety valve for the battery.

れている。2. Description of the Related Art As shown in FIG. 4, a conventional safety valve 1 for a sealed lead-acid battery is provided with a concave valve chamber 3 on the upper surface of a battery case lid 2 that closes a battery case containing an electrode plate group. A valve hole 4 is provided in the bottom portion 3a of the valve chamber 3 so as to pass through the battery case lid 2, and the valve hole 4 is surrounded and extends from the bottom portion 3a of the valve chamber 3 to the valve cylinder 5 inside the valve chamber 3.
And a cap-shaped rubber valve body 6 is covered on the valve cylinder 5 to prevent the cap-shaped rubber valve body 6 from coming off from the valve cylinder 5 at the time of releasing pressure on the battery case lid 2 in the upper part of the valve chamber 3. The upper lid 7 is supported and configured. A pressure release hole 8 is provided in the upper lid 7.

６が膨れて弁筒５との間の隙間からガスを排出し、電池
内圧の減圧時にはキャップ形ゴム弁体６が弁筒５に密着
して外部からの酸素の侵入を防ぐためのものである。In such a safety valve 1, when gas is generated during charging and the battery internal pressure rises, the cap-shaped rubber valve body 6 swells to discharge the gas from the gap between the valve cylinder 5 and the battery internal pressure. When the pressure is reduced, the cap-shaped rubber valve body 6 is in close contact with the valve cylinder 5 to prevent oxygen from entering from the outside.
【０００４】安全弁１のこのような機能が正常に働かな
くなると、電池内圧の増加により電槽が膨れたり（場合
によっては破裂する）、酸素が電池内に侵入して陰極が
酸化して、自己放電が大きくなり電池の保存特性が低下
したり、トリクル充電使用時にトリクル電流値が大きく
なり、格子腐食が大きくなって、電池寿命が短なった
り、電池に熱逸走が生じたりすることもある。When such a function of the safety valve 1 does not work normally, the battery cell swells due to an increase in the internal pressure of the battery (in some cases, it bursts), or oxygen enters the battery to oxidize the cathode and oxidize itself. The discharge may be large and the storage characteristics of the battery may be deteriorated, or the trickle current value may be large when the trickle charge is used, the lattice corrosion may be large, and the battery life may be shortened or the battery may be out of heat.
【０００５】このように密閉形鉛蓄電池の安全弁１は重
要な役割を果たすものであり、電池の使用期間中、該安
全弁１を正常に作動させる必要がある。As described above, the safety valve 1 of the sealed lead-acid battery plays an important role, and it is necessary to operate the safety valve 1 normally during the period of use of the battery.
【０００６】近年、密閉形鉛蓄電池の使用期間も長くな
り、電池の放電性能以外の部材についても、長期間その
安全性、信頼性が保たれる必要がある。In recent years, the sealed lead-acid battery has been used for a long period of time, and it is necessary to maintain the safety and reliability of members other than the discharge performance of the battery for a long period of time.

の表面を侵して両者に貼り付きを生じ易くさせるためと
考えられている。However, in the sealed lead-acid battery provided with the safety valve 1 as shown in FIG. 4, when the gas in the battery is discharged from the valve cylinder 5, sulfuric acid, which is an electrolytic solution, blows out. Alternatively, the sulfuric acid may be discharged together with the gas in a mist state. In this case, sulfuric acid adheres also between the valve cylinder 5 and the cap-shaped rubber valve body 6,
When the sulfuric acid adheres, the cap-shaped rubber valve body 6 easily sticks to the valve cylinder 5. This phenomenon is more likely to occur as the temperature rises. It is considered that this is because the sulfuric acid has a high concentration at a high temperature and attacks the surfaces of the cap-shaped rubber valve body 6 and the valve cylinder 5 to easily cause sticking to both.

易い問題点があった。Conventionally, ABC resin or polypropylene resin has been mainly used as the constituent material of the battery case, and chloroprene rubber has been mainly used as the constituent material of the rubber valve body 6, but in this combination, the rubber valve body 6 for the valve cylinder 5 is used. However, there is a problem that sticking is likely to occur.

ゴム弁体６の貼り付きを生じてしまうことがあった。In order to prevent the rubber valve body 6 from sticking to the valve cylinder 5, it has been proposed to use fluororubber as a constituent material of the rubber valve body 6, but the battery life is limited. Even if the rubber valve body 6 is made long and made of fluororubber, the rubber valve body 6 may stick to the valve cylinder 5 during long-term use.
