Description

【発明の詳細な説明】 本発明は、電池内部のカスに万一、引火する様なことか
あっても、電槽・蓋の破損事故を起さない蓄電池を提供
することを目的とする。

槽１および蓋２の厚さを２　ｍｍ以下とすることにより
、所Ｊｌ／Ｊ　（／封目的を達成することかできる。
本発明は、図示の如く電解液面４上の電池内空間６をカ
スの逸出に支障を来たさない程度の微少容積としたもの
であるから万一、電池内空間乙に滞留するカスに引火す
る様なことかあっても、そのカス量は微量であるため、
電槽１及び蓋２が破損するほどの爆発的現象は起らない
。
なお、ブロック状スペーサとしてはソリッドなものに限

他の手段としては、フロック状スペーサの挿入に代えて
蓋２の下面と電解液面４との凹陥を微少とする方法を採
用してもよい。
本発明は、叙上のとおり電池内部のカス爆発を阻止し、
電槽・蓋の破裂するおそれのない蓄電池を提供し得るも
のであるから、その工業的価値は犬である。
