Description
Claims (1)
- 内部に電池要素を収容し、貫通孔を有する筐体と、
前記筐体の外表面に対向する外側対向部および前記筐体の内表面に対向する内側対向部とを有し、前記貫通孔に挿入された弁体と、
前記内側対向部と前記筐体の前記内表面との間に配置され、前記内側対向部を前記筐体の前記内表面から遠ざかる方向に付勢する弾性付勢部材と、
前記外側対向部と前記筐体の前記外表面との間に配置され、前記弾性付勢部材の付勢力によって前記外側対向部と前記筐体の前記外表面とで挟持されることにより、前記筐体の内部を密閉するシール部材と、
前記貫通孔の軸方向において前記貫通孔と重ならないように前記筐体に設けられ、前記筐体の内圧が第1圧力に到達した際に作動する安全弁と、を備え、
前記弾性付勢部材には、前記貫通孔に連通する通気経路が形成されており、
前記筐体の内圧が前記第1圧力よりも小さい第2圧力に到達した場合に、前記外側対向部が前記シール部材から離間して前記筐体の内部と前記筐体の外部とが連通する、二次電池。
