Abstract
An elevator drive belt, while applying a friction force thereto, drives an elevator rope which links an elevator cage and a counterweight together. A rubber hardness of the belt ranges from about 50 to 90 degrees of JIS-A hardness so as to suppress creep slip due to a shearing strain while the elevator is in operation. Even if the elevator cage and the counterweight are reduced in weight and the friction force to be applied to the elevator rope decreases due to the weight reduction, a friction force onto the elevator rope from the elevator drive belt compensates and guarantees a drive force of the elevator.
