<p>PURPOSE:To allow a thin structure and both surfaces of a variable capacitor to be regulated by inserting a driver to a first through hole of a rotor from an upper surface side to be stopped, passing a driver via a second through hole of a stator from a lower surface side, and inserting to lock it to the hole of the rotor. CONSTITUTION:A movable electrode 29a side of a rotor 22 is placed in contact on an upper surface of a stator 24. The rotor 22 is contained in a cylindrical part 31a of a cover 25. A flange of the cover 25 is brought into contact with the upper surface of the stator 24. A rotor side terminal 35 is brought into contact with an external electrode 24b. Ends of pawls 34a, 34b of the cover 25 are so bent as to be introduced into a recess 28 of the stator 24, and the rotor 22, the stator 24 and the cover 25 are integrally engaged. A driver can be inserted to a through hole 26 of the rotor 22 via a through hole 32 of the cover 25 from an upper surface side of a variable capacitor 21 to be locked, and a driver can be inserted to the hole 26 of the rotor 22 via a through hole 27 of the stator 24 from a lower surface side to be locked.</p> |
