PURPOSE: An electronic parking brake is provided to be manufactured to be compact miniature by efficiently integrating apparatuses which perform power generation, movement direction changing, and parking cable manipulation. CONSTITUTION: An electronic parking brake comprises a housing(110), an operating unit(130), and an emergency operation unit(150). The operating unit is included in the housing and is connected to a parking cable(125). The operating unit moves the parking cable by straightly reciprocating with the driving of a motor. The operating unit comprises a gear unit(132), a nut screw(134), and a bolt screw(136). The emergency operation unit operates the operating unit while being selectively connected to the operating unit. The gear unit is rotated with the rotation of the motor. The nut screw is rotated with the gear unit and is connected to the emergency operation unit. The bolt screw is meshed with the nut screw and moves the parking cable.
