Abstract
本物品は、蓋と函体からなる電池ケースであって、函体に電極や電解液が収容されるものである。蓋には防爆弁が設けられている。防爆弁は、折り重ねて形成された折り重ね部と、当該折り重ね部の内側に設けられた薄板部と、防爆弁の中央部に薄板部よりも厚く形成された厚板部と、薄板部に設けられ、所定の圧力が作用すると破断する破断用溝部と、を備えている。このため、電池ケースの内部圧力が上昇した際、防爆弁が変形した後、破断用溝部を起点にして溝が開裂するので、内圧を外部へ開放することができる。This article is a battery case composed of a lid and a box, and the electrode and the electrolytic solution are housed in the box. The lid is provided with an explosion-proof valve. The explosion-proof valve includes a folded portion formed by folding, a thin plate portion provided inside the folded portion, a thick plate portion formed thicker than the thin plate portion in the center of the explosion-proof valve, and a thin plate portion. It is provided with a breaking groove portion that breaks when a predetermined pressure is applied. Therefore, when the internal pressure of the battery case rises, after the explosion-proof valve is deformed, the groove is opened from the breaking groove portion as a starting point, so that the internal pressure can be released to the outside.
