A pulley apparatus has: a pulley case (CA) disposed on one side of a vehicle body panel (11a) forming part of the vehicle; a pulley (80) disposed rotatable in the pulley case (CA); and a cable guide disposed in the pulley case (CA), wherein the cable guide is in sliding contact with a cable (18) which is led into an interior of the vehicle through the vehicle body panel (11a), and guides the cable (18) along vehicle body panel (11a) to direct the cable (18) to the pulley (80). As a result, when a load is applied to the cable (18), a case body of the pulley case (40) is pressed against the vehicle body panel (11a), thereby suppressing rattling noise and vibration of the pulley case (CA).
