Claim:
1. A device for unfurling and refurling a flexible structure comprising at least one tape spring having an axis of unfurling and of refurling parallel to an axis X, a rotor capable of rotating about an axis Y perpendicular to the axis X, and a stator supporting the rotation axis Y of the rotor, the tape spring being able, autonomously, to pass from a state in which the tape spring is wound around the rotor to an unwound state, the tape spring being mounted bent in a transverse direction into a shape of a U with two branches, wherein the tape spring comprises a first end of a first branch fixed rigidly to a first anchor point and a second end of a second branch fixed rigidly to a second anchor point secured to the rotor, the first end of the first branch of the tape spring being mounted between two jaws of the first anchor point, wherein the first and second anchor points are different from one another, and wherein the two ends of the two branches are the respective two opposite ends of the tape spring in the longitudinal direction X.
