Claims

[Scope of utility model registration request]

A pair of fixed side terminals and variable side terminals are each partially encapsulated and molded with insulating resin and integrally provided,
a resistive substrate formed by adhering to the surface a resistive film having both ends electrically connected to the electrodes using the exposed portion of one end of each of the fixed side terminals as an electrode; and a resistive substrate that is rotatable with respect to the resistive substrate. In a variable resistor comprising a slider provided to electrically connect the variable side terminal and the resistive film, a portion of the peripheral edge of the slider is protruded and the protruding portion is bent downward. a locking piece is formed on the variable side terminal, and the locking piece is located at two locations on the upper surface of the resistor board within the rotational locus of the locking piece, and when the slider rotates, the locking piece is attached to the variable side terminal, respectively. A pair of stopper pieces are formed to abut each other, and each of the stopper pieces is disposed in a bag-shaped resin part with respect to the direction of movement of the locking piece, so that the edge of the stopper piece in contact with the locking piece is exposed. A variable resistor characterized in that a stopper portion is formed by embedding each resistor.
