にもとの蓄電池に戻す還流機能を付加したものである。The path through which the electrolytic solution inside the storage battery overflows to the outside of the storage battery is such that the electrolytic solution inside the storage battery first flows out from the ventilation hole into the concave portion sealed by the upper lid, and then from the exhaust port communicating to the outside. The electrolyte flows out and overflows to the outside of the storage battery. The present invention focuses on disposing the shield in the lid structure portion where the function of the shield can be most effectively exerted, that is, it can be said that the electrolytic solution inside the storage battery is the final path through which the electrolyte overflows to the outside of the storage battery. Instead of arranging a shield so that the electrolyte that has flowed out into the shape part does not reach the exhaust port that leads to the outside of the lid, the electrolytic solution inside the concave part that is said to be the intermediate path where the electrolyte inside the storage battery overflows to the outside of the storage battery Sufficient overflow performance was obtained by adopting a lid structure in which a shield was placed at the vent to prevent the liquid from flowing out, and at the same time a reflux function was added to accurately return it to the original storage battery. .
