Provided is an electronic parking brake which efficiently uses a gap between a rear axle arm and a back plate and generates a large torque. According an embodiment of the present invention, the electronic parking brake device includes a rotary cam installed in the gap between a circular-disk-shaped back plate and a rear axle arm, is rotated with respect to an axis parallel to the central axis of the back plate on a plane parallel to the back plate, has a cam gear portion provided therein, and is electrically connected to a parking cable; a gear unit electrically connected to the cam gear portion and rotated with respect to the axis parallel to the rotary shaft of the rotary cam; and a driving shaft rotated with respect to the axial direction parallel to the plane of the back plate, and electrically connected to the gear unit to transfer power to the gear unit based on an electrical signal applied to a motor. |
