THERE IS PROVIDED A MACHINEROOM-IESS 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 (10), AND REDUCE A TOP CLEARANCE. A PAIR OF RIGHT AND LEFT CAGE-SIDE SHEAVES (16R, 16L) ARE DISPOSED IN THE UPPER SPACE OF THE CAGE (10), AND THE ROTATIONAL AXES OF THE TRACTION SHEAVE (17) AND THE CAGE-SIDE SHEAVES ARE EXTENDED IN THE LONGITUDINAL DIRECTION. A SHEAVE SUPPORTING BEAM (15) TO ROTATABLY SUPPORT CAGE-SIDE SHEAVES (16R, 16L) IS DISPOSED IN A SPACE BETWEEN AND UPPER BEAM (13) OF THE CAGE FRAME AND A CEILING OF THE CAGE (10), AND DISPOSED BELOW ROTARY SHAFTS OF THE CAGE-SIDE SHEAVES (16R, 16L).
