Document Type and Number:
WIPO Patent Application WO/2011/065635
Kind Code:
A1
Abstract:
Disclosed is an actuator. The actuator for enabling an object to enter or exit from a frame, comprises a support bracket installed at the frame; a movable bracket on which the object is mounted, and which is coupled to the support bracket such that the movable bracket is slidable in the entry/exit direction of the object; a winding wheel which is rotatably installed on the movable bracket, and which has an outer surface with a first winding portion and a second winding portion; a first wire having one end fixed at the exit side of the object and the other end wound in one direction onto the first winding portion; and a second wire having one end fixed at the entry side of the object and the other end wound in one direction onto the second winding portion. Thus, an actuator with a simple configuration which causes no mechanical friction can be obtained. In addition, manufacturing costs and noises of the actuator can be minimized.
