An object of the present invention is to provide a spiral spring assembly that is capable of suppressing lateral force generated in a central shaft. A spiral spring assembly () includes a central shaft (), a spiral spring () that is disposed on the periphery of the central shaft () and includes an outer end (), an inner end (), and a spiral portion () that connects the outer end () and the inner end () in a spiral form; an inner end fixing member () to which the inner end () is fixed so as to be capable of transmitting torque; and an outer end fixing member () to which the outer end () is fixed, and which is capable of moving relative to the inner end fixing member () within a predetermined section extending from a first state to a second state. The outer end () is fixed to the outer end fixing member () so as to be capable of transmitting torque and suppressing a lateral force that is generated in the central shaft () in a predetermined state within the predetermined section.
