Abstract: Disclosed is a connecting device of a parking cable for an electric parking brake, which connects an actuator for the electric parking brake with a parking cable. The connecting device includes a connector and a reaction force member. The connector includes a small diameter section having one side into which an outer peripheral surface of the parking brake is inserted, a large diameter section that extends from the small diameter section to have a diameter larger than that of the small diameter section, an axial cutout slit axially formed through upper and lower surfaces of an outer peripheral portion of the large diameter section such that protrusions circumferentially protruding from the actuator are inserted into the axial cutout slit through the large diameter section, a circumferential cutout slit that extends from an inner end of the axial cutout slit in a circumferential direction, and a cutout groove that axially extends from the circumferential cutout slit.

Abstract: In an embodiment, an electric parking brake system is disclosed. The system may include or comprise a pair of parking cables each connected to a brake. Additionally, the system may include or comprise a motor and a drive gear. The system may also include or comprise a planetary gear unit including or comprising a sun gear connected to the drive gear, a plurality of planetary gears gearedly connected with the sun gear, an internal gear formed along a revolving path of the planetary gears, and an output carrier connected to the planetary gears. The system may further include or comprise a screw-nut unit including a screw member and a nut member screwed to the screw member, the screw-nut unit being connected to the output carrier, and the parking cables being connected to opposite ends of the screw-nut unit, respectively.
