- the car 2 and the counterweight 3 are suspended within the hoistway 1 according to a 2:1 roping method by means of the first main ropes 19 and the second main ropes 20. That is, each of the first main ropes 19, which extends from the first end 19a to the second end 19b, is sequentially wrapped around the first car sash pulleys 26 and 25, the first car side return pulley 31, the first turning sheave 35, the first drive sheave 15, the first counterweight side return pulley 32, and the first counterweight sash pulley 29.

- the car 2 and the counterweight 3 are suspended within the hoistway 1 according to the 2:1 roping method by means of the first main ropes 19 and the second main ropes 20. Therefore, the loads applied to the first driving unit 12 and the second driving unit 13 can be lightened, and the first driving unit 12 and the second driving unit 13 can be reduced in size.

- the return pulleys 31 to 34 for guiding the first main ropes 19 and the second main ropes 20 to the sash pulleys 25 to 30 respectively are provided in the upper portion of the hoistway 1. Therefore, the first main ropes 19 and the second main ropes 20, which extend substantially horizontally, can be turned to extend substantially vertically, so the first main ropes 19 and the second main ropes 20 can be guided from the first drive sheave 15 and the second drive sheave 17 to the return pulleys 31 to 34 respectively without interfering with the car 2 or the counterweight 3.
- the first turning sheave 35 around which those portions of the first main ropes 19 which are located between the first drive sheave 15 and the first car side return pulley 31 are wound, is disposed in the upper portion of the hoistway 1. Therefore, winding angles of the first main ropes 19 with respect to the first drive sheave 15 and the first turning sheave 35 can be ensured, so an increase in traction ability can be achieved. Thus, a driving force of the first driving unit 12 can be transmitted to the first main ropes 19 more reliably, so the car 2 and the counterweight 3 can be raised/lowered more reliably.
- the second turning sheave 36 around which those portions of the second main ropes 20 which are located between the second drive sheave 17 and the second car side return pulley 33 are wound, is disposed in the upper portion within the hoistway 1. Therefore, winding angles of the second main ropes 20 with respect to the second drive sheave 17 and the second turning sheave 36 can be ensured, so an increase in traction ability can be achieved. Thus, a driving force of the second driving unit 13 can be transmitted to the second main ropes 20 more reliably, so the car 2 and the counterweight 3 can be raised/lowered more reliably.
- the first driving unit 12 and the second driving unit 13 are disposed within the region of the car 2 on the vertical projection plane of the hoistway 1. Therefore, the horizontal cross-sectional area of the hoistway 1 can further be reduced, so the entire elevator apparatus can further be reduced in size.

- those portions of the first main ropes 19 which are located between the first drive sheave 15 and the first counterweight side return pulley 32 may be wrapped around the first turning sheave 35. In this manner as well, winding angles of the first main ropes 19 with respect to the first drive sheave 15 and the first turning sheave 35 can be ensured, so an increase in traction ability can be achieved.

- those portions of the second main ropes 20 which are located between the second drive sheave 17 and the second counterweight side return pulley 34 may be wrapped around the second turning sheave 36. In this manner as well, winding angles of the second main ropes 20 with respect to the second drive sheave 17 and the second turning sheave 36 can be ensured, so an increase in traction ability can be achieved.
