Claims

[Scope of utility model registration request]

An insulating case with a rotating shaft attached and open at one end,
a substrate placed in the opening so that the surface on which the resistor is formed faces the inner surface of the case; and a substrate that contacts the resistor in a space formed between the case and the substrate and is driven by the rotating shaft. a slider provided in a storage section in the case and press-contacted with the electrode formed on the substrate together with the resistor; A high voltage variable resistor comprising an external connection pin coupled to a case, and a molded resin layer applied to an outer surface of the substrate to fix the substrate and the case, a means for communicating the storage portion and the space; , providing means in the storage section for holding one end of the spring means in a position over the pin insertion hole facing the storage section;
On the other hand, in the high voltage variable resistor, the external connecting pin has a tapered tip so that when the pin is inserted into the pin insertion hole, it comes into pressure contact with one end of the spring means.
