- 外装缶の開口上面を塞ぐ蓋と、前記蓋に設けた電解液注入用の注液口と、この注液口に装着される金属製の封止栓とを有しており、
前記注液口は、前記蓋に上下貫通状に形成された注入孔と、該注入孔のまわりに形成された上向きの受面を有する円状の凹部とを有し、
前記封止栓は、前記注入孔に上方から挿入される軸部と、該軸部の上端に張り出し形成されて、前記凹部の受面に受け止められる円形の頭部とを有し、前記軸部の軸心位置には、上方開口を有する拡開変形用の操作穴が凹み形成されており、
前記操作穴は、内径寸法が均一な小径部と、該小径部の上端に設けられた下窄まりテーパー状の被押圧面とを含み、
前記封止栓の前記頭部が前記受面に受け止められる状態において、前記軸部の下端部が前記注入孔の下端縁を越えて前記外装缶の内側へ侵入しており、かつ、前記操作穴の前記小径部が、前記注入孔の下端縁よりも下方まで形成されており、
前記注入孔の内周面と、該内周面に対向する前記軸部の外周面とが、上下方向にわたって径寸法が均一なストレート状に形成されており、
前記操作穴に上方開口より操作ピンを押し込み、前記軸部を拡開変形させると、該軸部の外周面が前記注入孔の内周面に押圧する密着状態となるように構成されており、
かかる密着状態で、前記頭部の外周縁と前記凹部の周縁部とを溶接することで前記注液口が封口されていることを特徴とする密閉型電池。 - 寸法公差を含む軸部の最大外径寸法が、寸法公差を含む前記注入孔の最小内径寸法よりも小さく設定されており、
寸法公差を含む頭部の最大外径寸法が、寸法公差を含む前記凹部の最小内径寸法よりも小さく設定されている請求項1記載の密閉型電池。
