An actuator includes a housing, a movable part, and an advancing unit that is at least temporarily connected to the movable part. The advancing unit includes a deformation unit and a deformer configured to deform the deformation unit with a vector component perpendicular to an effective direction of the actuator so that a total length of the deformation unit changes in the effective direction of the actuator as a result of the deformation. The movable part is configured to move in the effective direction of the actuator upon a removal of the vector component on the deformation unit and the deformation unit is disposed along the effective direction of the actuator upon the removal of the vector component on the deformation unit. |
