Abstract

In a rope supporting apparatus for an elevator, a column-like body along a guide rail provided within a hoist way is mounted on the guide rail through support bodies located at upper and lower ends of the guide rail. A rope end fixing member to which an end of a rope is fixed is fastened to the column-like body. The column-like body has a higher bending strength than the guide rail. Since the support bodies at both upper and lower ends of the column-like body are disposed with a sufficient distance between them, a pivoting reactive force, which is a load generated in the support bodies in a direction perpendicular to a center axis of the rail, becomes small, and any bending moment applied to the guide rail by the pivoting reactive force is smaller than the bending moment applied to the column-like body.
