Spring-type terminal member, electromagnetic contactor, and overload relay

The spring-type terminal member (24) has: spring-type terminals (11, 21) having conductive metal pieces (9a, 9b) that are screw-fastened to screw-type terminals of an electromagnetic contactor or an overload relay by screws (15, 14), and springs (10a, 10b) that engage with the conductive metal pieces (9a, 9b) by elastic force; and wire support members (19, 20) and an insertion port member (12) that hold the spring-type terminals (11, 21). The wire support members (19, 20) and the insertion port member (12) have interference portions (22, 23) that interfere with holes or grooves in screw heads of the screws (15, 14) to suppress rotation of the screws (15, 14). 弹簧式端子部件(24)具有：弹簧式端子(11、21)，其具有通过螺钉(15、14)而螺钉紧固于电磁接触器或过负载继电器的螺钉式端子的导电性金属件(9a、9b)、和通过弹性力而与导电性金属件(9a、9b)卡合的弹簧(10a、10b)；以及对弹簧式端子(11、21)进行保持的电线支承部件(19、20)及插入口部件(12)，电线支承部件(19)及插入口部件(12)具有与螺钉(15、14)的螺钉头的孔或槽发生干涉而抑制螺钉(15、14)的旋转的干涉部(22、23)。
