PURPOSE: An electric parking brake device is provided to reduce noise generation during the operation of a brake device by reducing errors in an assembly work. CONSTITUTION: An electric parking brake device comprises a caliper(210), a piston(220), a spindle(230), a nut member(250), and an actuator(100). The caliper covers a disk connected to the drive wheel of a vehicle. A pad which rubs against the disk is movably installed in the caliper. The piston is slidably installed in the caliper. The piston pressurizes the pad towards the disk. The spindle is rotatably installed in the caliper. The nut member is slidably installed in the caliper and is bolted to the spindle. The actuator provides power to the spindle.
