Claims

[Scope of utility model registration request]

(1) A tuner comprising a tuner having a coil wound around a bobbin, and a core whose outer periphery is coated with a moisture-proof material and whose inductance can be varied by moving it in and out of the coil.

(2) The tuner according to claim 1, wherein the moisture-proof member has whisker-like protrusions on its outer peripheral surface and is pressed into the bobbin.
