摘要： A release operation knob is provided at a distal end of a brake operation lever so as to move back and forth in a direction orthogonal to an axis of the brake operation lever. A locking pawl is provided swingably on the brake operation lever so as to engage with ratchet teeth which is fixedly placed on a vehicle body side. A rotational rod is provided so as to rotate on an axis extending substantially along an axial direction of the brake operation lever. The rotational rod includes a primary arm portion and a secondary arm portion are respectively provided on each end of a rod main body. The primary arm portion linked to the release operation knob, and the secondary arm portion is linked to the locking pawl.

摘要： 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. Thus, a parking brake device is made compact while a boost ratio of a booster mechanism of the parking brake device is secured.

摘要： An electrically operated parking brake apparatus that includes an electric motor and a screw mechanism The screw mechanism includes a screw-threaded shaft adapted to be rotationally driven by the electric motor, and a nut member meshing with the screw-threaded shaft, the nut member being movable along the screw-threaded shaft by the rotation of the screw-threaded shaft. The parking brake apparatus also includes a transmission member connected to the nut member for transmitting a brake operating force to a wheel brake, and a rotation preventing unit for preventing the rotation of the screw-threaded shaft so as to hold the brake operating force by fixing the position of the nut member relative to the screw-threaded shaft. The rotation preventing unit in one embodiment is an electromagnetic brake for confining the screw-threaded shaft to a stationary portion of a vehicle body.
