Description

この発明に係るエレベーター用巻上ロープは、エレベーターのかごを昇降路内で懸架するためのエレベーター用巻上ロープであって、複数の子縄が所定の樹脂で接着及び被覆されることによって一体化された内層体と、内層体の周囲を囲むように内層体の長手に沿って設けられ、複数の子縄が所定の樹脂で接着及び被覆されることによって一体化された外層体と、を備え、外層体は、内層体に対し、その長手方向に移動可能なものである。 An elevator hoisting rope according to the present invention is an elevator hoisting rope for suspending an elevator car in a hoistway, and is integrated by bonding and covering a plurality of strands with a predetermined resin. And an outer layer body that is provided along the length of the inner layer body so as to surround the inner layer body, and is integrated by bonding and covering a plurality of strands with a predetermined resin. The outer layer body is movable in the longitudinal direction with respect to the inner layer body.
