Abstract
【解決手段】 回動軸38を上刃電極21と下刃電極22との間の中心線L1に対して外側に設け、取付位置29で電極開閉ロッド17を上刃電極21と連結させる。電極開閉ロッド17が矢印C2方向に移動すると、回動軸38を中心に、上刃電極21が矢印D2方向に回動し、上刃電極21が下刃電極22に近接していく。このとき、上刃電極21と下刃電極22とを接触させることなく、上刃電極21と下刃電極22とが平行となる位置まで、上刃電極21が回動し、マイクロ波を印加できる。電極開閉ロッド17が更に矢印C2方向に移動すると、回動軸38を中心に、上刃電極21が矢印D2方向に回動し、上刃電極21が刃先から下刃電極22に近接して、刃先閉状態となる。
