The device has a connection unit (11) connecting between a permanent magnet (3) and a part (1). Lever (51) and eccentric axle (52) transform movements of the magnet by rotation of an input shaft (41) in two opposed directions with a speed reducing ratio between the rotation of the shaft and the magnet. A driving spring (43) turns an output shaft (42) in one of the directions when the input shaft turns in the direction. A blocking spring (44) stops the rotation of the shaft (42) in the opposed direction. A screw (61) and thread (62) rotate the shaft (42) to drive the movement of a part (2). |
