Claims

[Scope of utility model registration request]

A stator column that supports a stator plate is made to protrude outward from the variable capacitor main body, the protrusion is used as an external terminal of the stator plate, a nut is engaged with the protrusion, and the stator column is connected to the variable capacitor main body. In a variable capacitor mounting device in which a variable capacitor having a screw portion that is tightened to the top surface of a mounting board such as a printed circuit board,
The external terminal of the variable capacitor is passed through a hole formed in the mounting board, and the tip of the screw portion is arranged so that the tip of the screw portion does not protrude from the bottom surface of the mounting board when the variable capacitor is mounted on the mounting board. A variable capacitor mounting device configured by preselecting the length of the threaded part.
