Abstract

The present invention is related to a pulley structure that is provided with a tubular first rotating body around which a belt is wound a second rotating body provided inside the first rotating body so as to be rotatable relative to said first rotating body and a torsion coil spring which is housed in the space between the first rotating body and second rotating body. The torsion coil spring has: at one end an end region in which the outer peripheral surface makes contact with either the first rotating body or second rotating body through a self elastic restoring force in the large diameter direction of the torsion coil spring in a state in which the pulley structure is stopped; at the other end another end region in which the inner circumferential surface makes contact with the other rotating body in a state in which the pulley structure is stopped; and a center region. In cases where the torsion coil spring twists in the large diameter direction due to the relative rotations of the two rotating bodies the inner circumferential surface of at least a portion of the other end region of the torsion coil spring in the circumferential direction is separated from the other rotating body.
