A main rope group that suspends the car and the counterweight has: a first main rope that is wound sequentially around the first car suspending sheave, the first driving sheave, and the first counterweight suspending sheave, and a second main rope that is wound sequentially around the second car suspending sheave, the second driving sheave, and the second counterweight suspending sheave. The first driving machine, the first car suspending sheave, and the first counterweight suspending sheave, and the second driving machine, the second car suspending sheave, and the second counterweight suspending sheave, are respectively disposed at positions that are symmetrical in a vertically projected plane of a hoistway relative to a straight line that connects a pair of car guide rails that guide the car.
