Claims

[Scope of utility model registration request]

(1) Equipped with an insulating case made of a cylindrical insulator with a bottom, in which a rotor terminal and a stator terminal with a shaft are insert-molded on the bottom at a certain interval, and a contact piece and a stator electrode are formed inside this insulating case. The stator is disposed so as to pass through the shaft, and the stator terminal and the stator electrode are electrically connected to each other through the contact piece, and a metal rotor serving as a diagonal electrode is placed on the stator. The metal rotor is rotatably supported and disposed through the shaft, and a spring for press-contacting the metal rotor and the stator is disposed on the upper surface of the metal rotor through the shaft, and the upper end of the shaft is tightened. Trimmer capacitor.

(2) The trimmer converter and sensor according to claim 1, which is a registered utility model, in which the shaft is constructed by subjecting the tip of the rotor terminal to a drawing process.

(3) The trimmer capacitor according to claim 1, which is a registered utility model, wherein a recess is provided in the lower surface of the stator, a stator electrode is formed in the recess, and a contact piece is disposed within the recess.
