Abstract

본 발명은 이중 밀폐형 구조를 갖는 축전지용 커버에 관한 것으로서 상세하게는 축전지의 기울어짐에 따라서 누출되는 전해액의 손실을 방지하기 위하여 축전지의 기울기를 크게 하고, 커버 자체에서 누출된 전해액의 수용 공간을 확대하여 외부로 배출되는 전해액의 양을 줄일 수 있는 이중 밀폐형 구조를 갖는 축전지용 커버에 관한 것이다. 본 발명은 전해액이 수용되는 축전지몸체와 상기 축전지몸체의 상면을 밀폐시키는 이중 밀폐구조를 갖는 축전지커버에 있어서, 하측의 축전지몸체에 연통되도록 개구 형성되어 전해액이 주입되는 유입구를 각각 포함하는 하나 이상의 셀을 포함하는 하부커버; 전해액 및 가스를 외부로 배출시키는 배기구가 양측단에 형성되어 상기 하부커버의 상측에 체결되는 상부커버;를 포함하고, 상기 하부커버는 누출된 전해액 및 가스를 상기 배기구로 안내하는 배기출구가 포함된 배기셀을 최외각에 형성되는 최외각셀 보다 내측에 형성한다.
