Abstract
A linearly-displacing dual dial rods speed changing controller comprises a base, a wire hub seat, an advancing member, and a withdrawing member. The wire hub seat is fastened with a guide wire of a speed changer. The wire hub seat is controlled by dial rods of the advancing member and the withdrawing member to displace linearly in a reciprocating manner on the guide rail of the base, thereby actuating the guide wire to bring about a pulling action to attain the speed change.
