    Disclosed is an actuator for a parking brake which can fix the position of a rod in a housing even if a current is not supplied to a driving unit. According to one aspect of the present invention, the actuator for a parking brake comprises: a reduction gear transferring power of a motor to a parking part realizing parking braking; a lever allowing or blocking rotation of the reduction gear; and a driving unit moving the lever to a position for allowing or blocking rotation of the reduction gear. The driving unit includes a first member made of a magnetic substance, a second member facing the first member and made of a magnetic substance, and a rod wherein the end of one side thereof is coupled to the second member, and the end of the other side thereof can be attached to or separated from the lever. At least one between the first member and the second member consists of an electromagnet to attach or separate the rod to or from the lever by an attractive force or a repulsive force formed between the first member and the second member depending on the direction of an applied current.
