When a conventional machine roomless elevator system is formed by providing a traction machine between a passage for a cage and an inner surface of an elevator shaft, it becomes necessary that a cross-sectional area of the elevator shaft be increased in accordance with an increase in the sizes of the traction machine. In view of this problem, a machine roomless elevator system according to the present invention is provided with a cage hoisted by a rope; a counter weight hoisted by the rope; a traction machine provided in the portion of the interior of an elevator shaft which is higher than a cage stopping position on the uppermost floor, having a driving sheave around which the rope is passed and a motor for driving the driving sheave, and adapted to move the cage and counter weight in the vertical direction of the elevator shaft in accordance with the driving of the driving sheave; and a deflector wheel provided so that upper and lower ends with respect to the vertical direction of the elevator shaft of the deflector wheel are lower and higher respectively than those of the traction machine, positioned away from the traction machine in plan, and wound partially with the rope, the rope extending upward in the elevator shaft from the counter weight, being passed around the deflector wheel and driving sheave, and thereafter extending downward to the cage.
