In a mechanism in which a coil wound around a winding frame having a predetermined inner diameter is inserted into a pair of upper and lower pot-shaped cores, and a trimmer is inserted and moved into a through hole of the core to vary the inductance, the pot-shaped core is connected to an iron core. It is formed by a pair of upper and lower cores with different inner diameters and core inner diameter lengths, and the head is smaller than the inner diameter of the larger core inner diameter and larger than the smaller inner diameter of the iron core inner diameter, and the head is cylindrical and the lower part of the neck is reversed. A tack-shaped trimmer formed in a truncated cone shape is inserted and moved from the core side with the larger inner diameter of the iron core, and the gap length formed by the opposing inner diameter parts of the pair of upper and lower pot-shaped ferrite cores is adjusted to the head of the tack-shaped trimmer. A variable inductance mechanism characterized by effectively varying the inductance of a pot-shaped coil.
