The first and second main ropes have their individual upper end portions fixedly attached to an upper portion of the hoistway. On the car, there are mounted a pair of car hanging pulleys that horizontally guide the first and second main ropes from their individual upper end portions respectively, a drive unit that has a drive sheave around which the first and second main ropes from the car hanging pulleys are respectively wrapped, and a pair of wrap pulleys that guide the first and second main ropes from the drive sheave in direction downwardly of the car, respectively.
