The present invention relates to an actuator of an electronic parking brake. A stopper (90) restraining axial relative displacement with respect to a nut screw (40) is provided to an end part of a bolt screw (50) in order to prevent damage to a housing (10) caused by the nut screw (40) when the nut screw is excessively released and prevent the nut screw (40) and the bolt screw (50) from being separated from each other.
