VARIABLE CAPACITOR
Document Type and Number:
Japanese Patent JP3111916
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable a rotor to be adhered to a stator stably in a variable capacitor where a stator for forming a stator electrode and a rotor for forming a rotor electrode are accommodated in the recessed part of a case and a recessed part is closed by a cover.
SOLUTION: A cover 46 that is made of a metal has a cover body 55 for covering the upper surface opening of a recessed part 45 while leaving a hole 54 for adjustment that exposes the driver groove of a rotor 43, leg parts 56 and 57 that are engaged to a case 44 and fix the cover body 55 to the case 44, and a rotor terminal. The cover body 55 has the size of the full outer diameter of a variable capacitor 41, and a shape that is curved to apply an elastic force for pressing the rotor 43 toward the stator 42 is given to the cover body 55. A washer 60 that is extended in one piece from the cover body 55, is bent, and is located between the cover body 55 and the rotor 43, is preferably provided.
