Abstract
In an elevator apparatus, multiple cars are raised and lowered within a hoistway. The cars within the hoistway are adjacent to each other when located at the same height. If at least one of the cars is defined as a first car and a car adjacent to the first car is defined as a second car, the first car includes, in a face facing the second car a recess when projected onto a horizontal plane. At least a part of a car guide shoe is disposed in the recess.
