    • Within a case (4), are accommodated an electromagnet (8) having a fixed core (8c) and a movable core (8d) capable of contacting and separating from the fixed core (8c); a movable contact point support (7a) which moves in parallel with the movable core; a return spring (7b) which causes the movable contact point support to return to an initial position; and a driving lever (9) which rotates with a rotation support point portion (9a) provided on one end thereof as a support point, and which transmits attraction movement and release movement of the movable core to the movable contact point support. The rotation support point portion of the driving lever is fitted into and supported by a support point recess (5a) provided in an inner face of an extinction cover (5) mounted on the case.
    • 在壳体(4)内容纳有能够与固定芯(8c)接触和分离的具有固定芯(8c)和可动芯(8d)的电磁体(8)。 与所述可动芯平行移动的可动接点支撑部(7a) 复位弹簧(7b),其使可动触点支撑件返回到初始位置; 和驱动杆(9),其以设置在其一端上的旋转支撑点部(9a)作为支撑点旋转,并且将可动铁芯的吸引移动和移动移动到可动接触点支撑体。 驱动杆的旋转支撑点部分装配到设置在安装在壳体上的消光罩(5)的内表面中的支撑点凹部(5a)并由支撑点凹部支撑。
