There is provided a self-adjusting torque device which includes a driving module, a driven module and an adjusting module. The driving module is connected to a power inputting apparatus and has an acting force which is a first tension generated by the power inputting apparatus. The driven module is connected to a winding material and has an acting force which is a second tension applied on the winding material. The adjusting module is connected to the driving module and the driven module, and adjusts a distance between the driving module and the driven module according to the second tension force so as to keep the second tension identical with the first tension.
