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.
A reciprocatingly movable body drive mechanism comprising a tension member in the form of a rope or belt for reciprocatingly driving a reciprocatingly movable body, and a drive device for driving the tension member longitudinally thereof while pressing a specified region of the tension member sideways in contact with the tension member, the tension member being reeved around at least one sheave, and the drive device being in contact with a circular-arc region of the tension member as reeved around the sheave for pressing the circular-arc region against the sheave, wherein the drive device comprises a belt transmission disposed alongside the tension member and revolvingly movable alone a tension member extension route, a pressing mechanism for pressing a belt surface of the belt transmission into contact with the tension member, and a drive motor for driving the belt transmission.
An elevator apparatus comprising a reciprocatingly movable body reciprocatingly movably provided in a path of reciprocating movement, and a mechanism for reciprocatingly driving the body, the elevator apparatus being characterized in that the reciprocatingly driving mechanism comprises:
