ELEVATOR DEVICE

To achieve the purpose of the present invention, the present invention provides an elevator device comprising an elevating path (1) which is formed vertically inside a building; a pair of car rails (2) installed vertically adjacent to both inner walls of the elevating path (1); a car (3) which moves from top to bottom inside the elevating path (1) along the pair of car rails (2); a pair of balance weight rails (5) which are installed vertically adjacent to one inner wall of the elevating path (1) and moves a balance weight (4) from top to bottom in direct opposition to the movement of the car (3); and an elevating unit which moves the car (3) and the balance weight (4). The elevating unit comprises a traction machine (10) which delivers power to move the car (3) and installs a rotary shaft to be parallel to the one inner wall of the elevating path (1); a main sheave (20) which is installed on one side of the traction machine (10) to be rotated in the a direction same as the rotary shaft of the traction machine (10); a supporting stand (50) which is installed on upper end of the car (3); a car suspension sheave (60) which is installed on the supporting stand (50) to be able to rotate; an auxiliary sheave (40) which is installed on upper end of the balance weight (4) to be able to rotate; and a tension member (30) which is wired on the main sheave (20) via the car suspension sheave (60) in the state that one end is fixated on the elevating path (1) and the other end is wired on the auxiliary sheave (40). The rotary shaft of the main sheave (20) is at right angles to the rotary shaft of the auxiliary sheave (40).
