In an electric parking brake device configured in such a way that a parking brake state resulting from pulling of a brake cable is released by loosening the brake cable, the brake cable is formed by twisting together a plurality of wires in such a way as to generate a twisting force in a fixed direction when pulled, and the direction in which the twisting force generated by the brake cable in a pulled state acts on a screw shaft is set to be the same direction as the direction in which a nut is rotated to loosen the brake cable. This makes it possible to reduce an operating sound and to reduce wear of members constituting a rotation restricting device.
