Abstract
A sliding variable resistor includes a sliding base, a first supporting pole, two buffering members, a substrate, a casing assembly, an anchoring plate, a driving member, a driven member, a belt, and a belt guard. The sliding base includes two first through hole and at least one variable resistor sheet. The first supporting pole is inserted into the two first through hole. The first supporting pole has its two ends abut against the first buffering seats, respectively. The substrate is engaged with the two buffering members. The two buffering members are arranged in the casing assembly. The anchoring plate is fixedly arranged on the casing assembly. The belt is engaged with the driving member and the driven member, respectively. The belt guard is fastened to the sliding base, and is engaged with the belt. As such, the sliding base, while sliding, can have an improved smoothness.
