Abstract
In an elevator apparatus, a hoisting machine includes a driving sheave, and a motor portion that rotates the driving sheave, and is disposed in an upper portion inside a hoistway. A suspending unit is wound sequentially around a first car suspending sheave, a second car suspending sheave, the driving sheave, and a counterweight suspending sheave. The second car suspending sheave, the driving sheave, and the counterweight suspending sheave are disposed on a first side of a car guide rail center line that connects first and second car guide rails when viewed from directly above. A portion of the motor portion is disposed between a back surface of the second car guide rail and a hoistway wall. The driving sheave is disposed so as to overlap with the second car guide rail when viewed from a landing side.
