Abstract: 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 1 includes a central shaft 2; a spiral spring 3 that is disposed on the periphery of the central shaft 2 and includes an outer end 3a, an inner end 3b, and a spiral portion 3c that connects the outer end 3a and the inner end 3b in a spiral form; an inner end fixing member 4 to which the inner end 3b is fixed so as to be capable of transmitting torque; and an outer end fixing member 5 to which the outer end 3a is fixed, and which is capable of moving relative to the inner end fixing member 4 within a predetermined section extending from a first state to a second state. The outer end 3a is fixed to the outer end fixing member 5 so as to be capable of transmitting torque and suppressing a lateral force that is generated in the central shaft 2 in a predetermined state within the predetermined section.
