ABSTRACT:
A rotary electronic component of the present invention has a sealed structure for the upper part of a contact section toward the side of an operating knob. In this structure, a rotor with a lower ring magnet is rotatably disposed on a concavity of a case with an open top. The top of this concavity is sealed with a sheet. An operating member with operating knob provided with an upper ring magnet is disposed on the sheet so that the rotor and the operating member co-rotate by the attractive force between the magnets.
