Abstract
A trimmer capacitor is encased in an insulating case. The insulating case holds a stator terminal embedded therein. A dielectric stator is fixedly received in the insulating case and is provided with a stator electrode. The stator electrode is electrically connected to the stator terminal by contact with the exposed portion of the stator terminal within the insulating case. A metal rotor having a rotor electrode is placed on the dielectric stator. A projecting step is formed on the upper surface of the metal rotor. The projecting step is received in a throughgoing hole formed in one end of the rotor terminal and in this state the metal rotor is rotatably supported with respect to the rotor terminal. The throughgoing hole is located in the center of a dish-shaped spring portion. One end of the rotor terminal, including the dish-shaped spring portion, is locked by the upper edge of the insulating case, whereby a suitable amount of torque is attained by the springiness thereof with respect to the rotation of the metal rotor.
