Abstract: An pulley set includes a base, a seat, and an adjusting unit, wherein the base defines a hollow space with one side of the hollow space forming a vertical wall having a screw hole and the other side of the hollow space forming an inclined wall. A guiding plane parallel to the inclined wall extends from the vertical wall, and positioning slots are respectively formed in the guiding plane and the inclined wall. The seat is mounted within the hollow space of the base and has two inclined planes corresponding to the inclined wall and the guiding plane. The adjusting unit is disposed in the screw hole of the base for pushing against the seat such that adjusting the adjusting unit will cause the seat to move along the inclined wall and the guiding plane of the base.
