Abstract
A high-voltage variable resistor unit capable of permitting a circuit board to be decreased in size and preventing interruption of output thereof. A circuit board having a resistive pattern including a plurality of variable resistance elements formed on a front surface thereof is arranged in a board receiving chamber. A terminal fitment and a slide element are so arranged that a contact point between a plate-like section of the slide element and a contact section of the terminal fitment is defined in a manner to be spaced from the front surface of the circuit board toward an operation member. A fit projection of the terminal fitment is fitted in a fit hole of the insulating casing. A silicone adhesive is applied to a board supporting rib of the insulating casing to the circuit board thereto. The adhesive is constructed so as to exhibit sufficient to prevent elastic force of the arm from being reduced to a degree of causing a failure in contact between the contact section and the supported section of the slide element when it is cured.
