Abstract: A parking brake device includes a booster mechanism having an intermediate lever pivotally supported at a bracket, and a movable pulley supported at a tip end of the intermediate lever. When a first operation cable is pulled by operating a parking brake pedal, the movable pulley around which an intermediate portion of the inner cable is wound is pulled with doubled force, and the doubled pulling force is further boosted due to the lever ratio of the intermediate lever which supports the movable pulley, and is transmitted via an equalizer and a second operation cable to a brake device provided at a wheel with the pulling force boosted to a boost ratio twice as much as the lever ratio. By combining the movable pulley and the intermediate lever, the length of the intermediate lever to obtain the same boost ratio can be made half as compared with the case where only the intermediate lever is used, thereby making the booster mechanism compact.
