An actuator for adjustment of a flexible line such as a cable or rope. The actuator includes a screw threaded spindle and a cooperatively engaging adjustment member having a nut with an internal screw thread that is in threaded engagement with an external screw thread of the spindle. The adjustment member is rotatable relative to the spindle to cause axial movement of the spindle. A turning block or pulley is mounted on an end of the spindle for rotation on an axis extending transversely with respect to the axis of the spindle and the flexible line is retained in relation to the spindle. The flexible line is passed around the turning block or pulley for adjustment of the flexible line by axial movement of the spindle. |
