The container 1 is divided into a plurality of cells 10 and each of the cells 10. Electrode and electrolyte are contained inside. And, the main cover 2 is installed on the upper portion of the container 1, the electrolyte inlet 20 to inject the electrolyte into the interior of the container (1); A vent path 21 for discharging hydrogen gas generated therein and a gas discharge hole 23 on the outlet side thereof are provided. Each electrolyte inlet 20 is provided with a through-hole 22 through the vent pass 21 is blocked by a vent cap (4).

벤트캡(4)은 셀 내부로부터 발생되는 가스를 납축전지 외부로 배출시킬 수 있게 하는 벤트홀(42)을 가지며, 벤트홀(42) 내측의 중공부(41)에는 저지턱(43)을 형성시켜 전해액의 누출을 방지하도록 구성되어 있다. The vent cap 4 has a vent hole 42 through which gas generated from the inside of the cell can be discharged to the outside of the lead acid battery, and a blocking jaw 43 is formed in the hollow part 41 inside the vent hole 42. It is configured to prevent leakage of the electrolyte solution.

그러나 이와 같이 구성된 종래의 메인카바는 납축전지가 심하게 기울어지거나 크게 흔들리는 경우 컨테이너(1)에 담겨진 전해액이 벤트캡(4)의 중공부(41) 내부로 유입되고, 중공부(41)내로 유입된 전해액은, 비록 저지턱(43)이 형성되어 있더라도, 벤트홀(42)을 걸쳐 메인카버의 벤트패스(21)를 지나 가스배출공(23)을 통 해 외부로 누출되는 문제점이 있다. 또한, 외부에서 발생되는 화염이 아무런 저항 없이 가스배출공(23)을 거쳐 벤트패스(21)를 통해 납축전지 내부의 전기화학적 반응으로 생성된 수소가스와 반응하여 폭발이 발생 되는 문제점이 있다.However, in the conventional main cover configured as described above, when the lead acid battery is severely tilted or shakes greatly, the electrolyte solution contained in the container 1 flows into the hollow part 41 of the vent cap 4, and is introduced into the hollow part 41. Even though the stopper 43 is formed, the electrolyte leaks to the outside through the gas discharge hole 23 through the vent pass 21 of the main cover over the vent hole 42. In addition, there is a problem that the flame generated from the outside reacts with the hydrogen gas generated by the electrochemical reaction inside the lead acid battery through the vent pass 21 through the gas discharge hole 23 without any resistance, there is a problem that an explosion occurs.
