Abstract
A pulley structure may include: a tubular outer rotating body having a belt looped thereon; an inner rotating body which is disposed radially inside the outer rotating body and which is rotatable relative to the outer rotating body; and a torsional coil spring which is arranged in a spring accommodating space formed between the outer rotating body and the inner rotating body. At least in a state in which the pulley structure has not been operated even once, grease containing a rust inhibitor is applied to an opposing surface of the inner rotating body opposing an inner peripheral surface of the torsional coil spring.
