Abstract
The present invention is to provide a hybrid core rope which does not require maintenance or a hybrid core rope capable of reducing a maintenance task. The hybrid core rope includes a resin solid core in which a plurality of spiral grooves is formed in the longitudinal direction on an outer peripheral surface thereof, a plurality of fiber bundles respectively spirally wound around the outer peripheral surface of the resin solid core along the plurality of spiral grooves, the fiber bundles having thickness to fill the spiral grooves, and a plurality of steel strands spirally wound around the outer peripheral surface of the resin solid core around which the fiber bundles are wound. The fiber bundles and the strands are respectively wound so as to have angles which are not parallel to each other.
