A main rope (13) is reeved around the sheave and a car is suspended from the rope for vertical movement. The reduction gear assembly includes a pair of large and small gears (8B,8D). The small and large gears are connected respectively to the input and output shafts of the reduction gear assembly and are disposed in face-to-face relationship. One bearing of the sheave is integral with a gearbox of the reduction gear assembly, and the large gear is supported in an overhanging manner by the shaft of the sheave.
