Abstract:
1. An electric parking brake comprising a motor which forms torque through an electric device; multi-stage gears coupled with the motor; a gear wheel which is mechanically linked with the multi-stage gears; a screw nut which has a hollow structure, and is integrally formed with an inner circumferential surface of the gear wheel; a spindle geared with an inner circumferential surface of the screw nut to move in a shaft direction according to rotation of the gear wheel; a parking cable linked with the spindle at an outlet side of the spindle remote from the gear wheel; and a stopper member fixed to an outer circumferential surface of a second end opposite to a first end of the spindle linked with the parking cable to prevent the spindle from excessively rotating when breaking is released, wherein the parking cable linked with the first end of the spindle is pulled to be positioned to an inner part of the screw nut in braking.
