Claims

[Scope of utility model registration request]

An insulating cap is formed by insert-molding a stator terminal into an insulating case that has an opening at the bottom and a retaining part near the opening, and an engaging part that fits the engaging part of the insulating case. A variable capacitor characterized in that a rotor terminal, a rotor, and a dielectric are housed inside by fitting through an opening of the insulating case.
