Claim:
A machineroom-less elevator, comprising: a cage that moves vertically in an elevator shaft, the cage is guided by a pair of right and left cage-side guide rails and includes a pair of right and left doors disposed on a front surface of the cage that open and close in the right and left directions; a counterweight which includes a counterweight-side sheave, and moves vertically behind the cage along a rear wall of the elevator shaft, the counterweight is guided by a pair of right and left counterweight-side guide rails; a traction sheave which is disposed on a top of the elevator shaft near one of right and left sidewalls of the elevator shaft, and is driven in rotation about a rotational axis extending from the sidewall to the rear wall when viewed vertically from above; a driving apparatus which drives the traction sheave in rotation; a pair of right and left cage-side sheaves which suspend and support the cage on an upper part thereof, and which rotate about rotational axes parallel to a rotational axis of the traction sheave, or about rotational axes extending at an angle adjacent to the rotational axis of the traction sheave; a first diverting sheave which is disposed lower than the traction sheave near the sidewall, and is rotated about a first rotational axis extending in the right and left direction; a second diverting sheave which is disposed higher than the first diverting sheave said second diverting sheave is near the rear wall, and is rotated about a second rotational axis, perpendicular to the first rotational axis, extending in the rear and front direction; and a hoist rope passed around the traction sheave, with a first end of the hoist rope suspending the cage through the pair of right and left cage-side sheaves, and a second end thereof suspending the counterweight through the first and second diverting sheaves and the counterweight-side sheaves.
