Abstract
A driving device for a parking brake system includes a casing shift member, a brake cable and a driving member. The casing shift member includes a cable casing. The brake cable is mounted through the cable casing. The driving member has a driving unit connected to and driving the casing shift member to perform a longitudinal motion. Thus the cable casing applies a force on the brake cable so as to perform a brake work. Because the brake cable is tightened with the force provided by the cable casing, the brake cable is only bent slightly. Thus the curvature of the brake cable is small. That prevents the brake cable from being damaged and prolongs a life span of the brake cable. Moreover, a mechanical efficiency of the driving device is improved because the brake cable is tightened with the force provided by the cable casing.
