An elevator comprising guide rails for guiding a cage and a counterweight installed in an elevator shaft. A supporting structure is also provided in the elevator shaft independently of the cage guide rails and the counterweight guide rail. The supporting structure comprises a column extending upward from the bottom of the elevator shaft, and a supporting beam secured to the upper end part of the column. A driver having a drive sheave is secured to the supporting beam. A main rope is hung on the drive sheave. The cage and the counterweight are suspended by the main rope. The guide rails can thereby be reduced in size and production cost thereof can be reduced.
