ABSTRACT:
When an actuator is driven, a stationary element continuously generates a pressing force for spreading in a radial direction such that the stationary element is relatively retracted into movable elements positioned at both ends of the stationary element. As a result, a distance between the movable elements adjacent to each other is reduced, and a contracting operation is performed. When the actuator is not driven, only a relatively low frictional force is generated between the moving elements and the stationary element. Hence, the movable elements and the stationary element can change relative position by small external force.
