Zusammenfassung:	A torsion unit and device, and use in the preparation of a vehicle cover. The torsion unit comprises a processed elastic material (1) with torque and a connection structure (2) to form several continuous torsion rings, and two or more torsion units are connected to form the torsion device. The structures of the torsion unit and the torsion device have a tensile stress and a directional folding force, easily realizing automatic retraction to recover to an original folded state. A torsion spring structure body formed by several torsion units provided in an expanding manner can become a support frame of a cover for living. The support frame is reasonably combined with an existing conventional sunshade material or waterproof material to obtain a vehicle cover having a support frame provided with a torsion spring structure. The vehicle cover has a foldable frame which is able to support the vehicle cover, the vehicle cover stays above the vehicle lacquer surface, avoiding frequent friction between the cloth surfac
