PULLEY STRUCTURE

This pulley structure (1) has an air passage (10) which is formed at a position offset radially from the rotation axis of a first rotating body (2) and which connects a spring accommodation space (8) and the outside, the spring accommodating space (8) being formed between the first rotating body (2)...

Beschreibung
Zusammenfassung:	This pulley structure (1) has an air passage (10) which is formed at a position offset radially from the rotation axis of a first rotating body (2) and which connects a spring accommodation space (8) and the outside, the spring accommodating space (8) being formed between the first rotating body (2) and a second rotating body (3). At least a part of the air passage (10) is formed in an end cap (5) for closing an opening (21) of the first rotating body (2), the opening (21) being located on one side of the first rotating body (2) in the rotation axis direction. The end cap (5) closes the opening (21) of the first rotating body (2) so that the spring accommodation space (8) is not in communication with the outside toward the one side in the rotation axis direction except through the air passage (10).
