<p>PROBLEM TO BE SOLVED: To stabilize the contacting state of a rotor with a stator and, at the same time, to make the rotating torque of a rotor relatively stronger. SOLUTION: In a variable capacitor in which a cover 24 which rotatably holds a rotor 23 against a stator 22 is provided and a hole for adjustment into which a tool for rotatably operating the rotor 23 can be inserted and, at the same time, a spring action section 35 which comes into contact with the rotor 23 and press-contacts the rotor 23 with the stator 22 is provided around the hole for adjustment, three or more projections 36 are provided in the spring action section 35, so that the projections 36 may be arranged along the direction of rotation of the rotor 23 and may substantially come into point-contact with the rotor 23. Therefore, the machining dispersion of the rotor 23 and the cover 24 can be absorbed and the contacting state of the rotor 23 with the stator 22 is stabilized, and then, the rotating torque of the rotor 23 can be made relatively stronger.</p> |
