PROBLEM TO BE SOLVED: To reduce the horizontal projection area of a hoistway and the bottom section depth of the hoistway by increasing the area of the hoistway bottom section against the horizontal projection area of the hoistway, forming an engine room on this expanded area section, and arranging part of a drive device in this engine room.SOLUTION: A car 7 and a balance weight 8 in a hoistway 2 are connected by a rope 9, a drive sheave 10 driving the rope 9 is rotated by a drive device 11 fixed to a hoistway bottom section 2A directly below the car 7 by a support base 12, and the car 7 and the balance weight 8 are vertically moved. A space is formed below the lower floor 3 by the depth (m) from the building wall 2B of the hoistway 2 to expand the area of the hoistway bottom section 2A against the horizontal projection area of the hoistway 2, and an engine room M is formed in this space. The main body of the drive device 11 is stored in the engine room M, and the car 7 and the balance weight 8 are vertically moved by the drive device 11 via the rope 9 wound on the drive sheave 10.
