Abstract
In an elevator rope, an inner layer rope has: an inner layer rope fiber core; a plurality of inner layer strands; and a resin inner layer rope coating body that is coated onto an outer circumference. Inner layer strands are twisted together on an outer circumference of the inner layer rope fiber core. The inner layer strands have: an inner layer strand fiber core that is disposed centrally; and a plurality of steel inner layer strand wires that are twisted together on an outer circumference of the inner layer strand fiber core. In addition, a plurality of steel outer layer strands are twisted together on an outer circumference of the inner layer rope.
