  • a first end 10a of each main rope 10 is connected to the rope support portion 11 through the intermediation of a car side rope stop 12.
  • a second end 10b of each main rope 10 is connected to the machine base 6 through the intermediation of a counterweight side rope stop 13.
  • a rotatable deflector sheave 16 for guiding the main ropes 10 from the driving sheave 9 to the car suspension sheaves 14.
  • the deflector sheave 16 is arranged such that its rotation shaft extends parallel to the rotation shaft of the driving sheave 9 and the deflection sheave 16 is arranged in a plane perpendicularly crossing the rotation shaft of the driving sheave 9 and including the driving sheave 9. That is, in a vertical plane of projection, the driving sheave 9 and the deflector sheave 16 are arranged in a straight line.
  • the main ropes 10 are wrapped around the car suspension sheaves 14, the deflector sheave 16, the driving sheave 9, and the counterweight suspension sheave 15 in the stated order to reach the second ends 10b. That is, the car 4 and the counterweight 5 are suspended in the 2:1 roping system.
