    【実用新案登録請求の範囲】
  1. 絶縁筒内部に板状の非線形抵抗素子が積み重ね
    られ、この絶縁筒の両端面を気密に閉鎖する端板
    と前記非線形抵抗素子との間にばねが介装されて
    前記非線形抵抗素子相互間に接触圧力が与えられ
    るとともに前記端板の少なくとも一方は前記絶縁
    筒内部に生じうる過大圧力を外部へ放出せしめる
    ための開口を備え、この開口を常時気密に閉鎖す
    るとともに所定圧力において放圧動作をする放圧
    板を備えた避雷器の構造において、前記放圧板が
    前記開口を備えた端板の絶縁筒内部側に配される
    とともに前記ばねのばね力により前記開口を気密
    に閉鎖していることを特徴とする避雷器の構造。
