<p>The present invention relates to a pulley structure for wire coupling. More particularly, the present invention comprises: a truncated cone-shaped groove (100) that includes a first guide groove (110) formed in a thread shape on an outer circumferential surface; and a cylindrical guide pulley (200) that is coupled with a lower surface of the groove (100) and includes a second guide groove (210) formed on an outer circumferential surface. A wire (W) can be moved to the second guide groove (210) of the guide pulley (200) along the first guide groove (110) of the groove (100), and thus the coupling between the cable wire (W) and the pulley is facilitated for improved convenience of operation. Also, damage to the cable wire (W) is reduced during operation for the effect of improved marketability.</p> |
