Beschreibung
Zusammenfassung:	The present invention provides a pulley structure (10) provided with: a tubular outer rotating body (2) having a belt (B) looped thereon; an inner rotating body (3) which is disposed radially inside the outer rotating body (2) and which is rotatable relative to the outer rotating body (2); and a torsional coil spring (4) which is arranged in a spring accommodating space (8) fonned between the outer rotating body (2) and the inner rotating body (3). At least in a state in which the pulley structure (10) has not been operated even once, a grease (200) containing an antirust agent is applied to an opposing surface (34) of the inner rotating body 3 opposing an inner peripheral surface (42) of the torsional coil spring (4).
