ABSTRACT:
There is provided an machineroom-less elevator which can reduce the pit depth in a bottom part of an elevator shaft, mostly perform maintenance work on an upper space of a cage, and reduce a top clearance. A pair of right and left cage-side sheaves are disposed in the upper space of the cage, and the rotational axes of the traction sheave and the cage-side sheaves are extended in the longitudinal direction. A sheave supporting beam to rotatably support cage-side sheaves is disposed in a space between and upper beam of the cage frame and a ceiling of the cage, and disposed below rotary shafts of the cage-side sheaves.
