摘要： The invention provides an elevator apparatus comprising a cage 1 disposed inside a path of upward or downward movement vertically movably, a counterweight 2 vertically movable with the upward or downward movement of the cage 1, and a lift drive mechanism for driving the cage 1 upward or downward. The drive mechanism comprises a sheave 42 disposed inside the path, ropes 3 extending along a route around the sheave 42, and a drive device 5 in engagement with the ropes 3. The drive device 5 comprises a belt transmission provided alongside the ropes 3 and revolvingly movable along the rope extension route, a mechanism for pressing a belt surface of the belt transmission into contact with the ropes 3, and a drive motor for driving the belt transmission. The cage can be driven upward or downward without using any traction sheave, while the cage can be reduced in weight.
