Summary:PURPOSE: To always obtain a stable reversing action, regardless of adjusted position of the adjustment dial. CONSTITUTION: In a thermally-activated overload relay that is equipped with a moving plate supported reversibly around the fulcrum at an end and a tension spring to reverse-drive the moving plate and devised, so as to reverse-drive the moving plate by the tension spring at the middle portion as a reverse action mechanism for making and breaking the contact driven by a release lever, a protruded portion is formed at the middle portion of the tension spring to constitute so that the release lever is made to contact with the protruded portion of the tension spring. 본 발명은 조정 다이얼의 조정위치에 관계없이 항상 안정된 반전동작을 얻을 수 있도록 하는 것으로서, 그 수단으로서, 석방 레버로 구동되는 접점 개폐용의 반전 동작 기구로서, 한 단을 지점으로 하여 반전 가능하게 지지된 가동판과, 해당 가동판을 반전 구동시키기 위한 인장 스프링을 구비하며, 인장 스프링의 선조의 중복을 석방 레버에 의해 압압(押壓)하여 가동판을 반전 구동되도록 한 열 동형 과부하 계전기에 있어서, 상기 인장 스프링의 선조의 중복에 돌기부를 형성하고, 해당 인장 스프링의 돌기부에 석방 레버를 당접시키도록 구성한다.
