Abstract
A variable resistor is constructed to prevent bending strain from spreading to the conductive portions to a resistor when bending is executed with respect to the external connection portions of metallic terminals. The variable resistor provides a low-profile variable resistor capable of stabilizing the electrical connection between the metallic terminals and the resistor. This variable resistor includes metallic terminals insert-molded in a board, and a slider sliding on the resistor disposed on the board. The slider is rotatably installed on the board by caulking the grommet disposed on a first metallic terminal,and the conductive portions of second metallic terminals are conductive to the resistor. Each of the external connection portions is extended out of the bottom of the board, and is folded upwardly at the position of the corresponding notch. Thereby, bending stress is minimized, the looseness of the metallic terminals with respect to the board is prevented, and the reliability of the connection between the resistor and the conducting portions is increased.
