The load supporting member includes: an impregnation material and reinforcement fiber bodies, which continuously extend in a longitudinal direction of the rope, are embedded in the impregnation material, and are configured to support a load acting in the longitudinal direction. The reinforcement fiber bodies include corrugated reinforcement fiber bodies which have, at least in part, a corrugated shape in a section parallel to the longitudinal direction. The corrugated reinforcement fiber bodies have such a length that a total length thereof given when the corrugated reinforcement fiber bodies are straightened is equal to or larger than 1.1 times a total length of the load supporting member. ## Claims ### Claim 1 A rope, comprising: a load supporting member including: an impregnation material; and reinforcement fiber bodies, which continuously extend in a longitudinal direction of the rope, are embedded in the impregnation material, and are configured to support a load acting in the longitudinal direction; and a covering member covering an outer periphery of the load supporting member, wherein the reinforcement fiber bodies include corrugated reinforcement fiber bodies which have, at least in part, a corrugated shape in a section parallel to the longitudinal direction, and wherein the corrugated reinforcement fiber bodies have such a length that a total length thereof given when the corrugated reinforcement fiber bodies are straightened is equal to or larger than 1.1 times a total length of the load supporting member. ### Claim 2 A rope, comprising: a load supporting member including: an impregnation material; and reinforcement fiber bodies, which continuously extend in a longitudinal direction of the rope, are embedded in the impregnation material, and are configured to support a load acting in the longitudinal direction; and a covering member covering an outer periphery of the load supporting member, wherein the load supporting member further includes a plurality of cross members, which are spaced apart from each other in a longitudinal direction of the load supporting member and embedded in the impregnation material, wherein the cross members are each elongated so as to extend in a direction perpendicular to the longitudinal direction of the load supporting member, wherein the cross members have an elastic modulus larger than an elastic modulus of the impregnation material, wherein the reinforcement fiber bodies include corrugated reinforcement fiber bodies, which are, at least in part, wound around the cross members and formed into a corrugated shape, and wherein the corrugated reinforcement fiber bodies have such a length that a total length thereof given when the corrugated reinforcement fiber bodies are straightened is larger than a total length of the load supporting member. ### Claim 3 (depends on 2) The rope according to claim 2, wherein the corrugated reinforcement fiber bodies and the cross members form each of a plurality of composite layers which are arrayed in a thickness direction of the load supporting member. ### Claim 4 (depends on 3) The rope according to claim 3, wherein the reinforcement fiber bodies include parallel reinforcement fiber bodies being bundles of reinforcement fibers arranged in parallel with the longitudinal direction of the load supporting member, wherein the parallel reinforcement fiber bodies are arranged at a center of the load supporting member in the thickness direction, and wherein the composite layers are arranged on both sides of the parallel reinforcement fiber bodies in the thickness direction of the load supporting member. ### Claim 5 (depends on 3) The rope according to claim 3, wherein the corrugated reinforcement fiber bodies have a total length which is larger in the composite layer arranged closer to a surface of the load supporting member in the thickness direction. ### Claim 6 (depends on 2) The rope according to claim 2, wherein the corrugated reinforcement fiber bodies have an elastic modulus which is smaller in the composite layer arranged closer to the surface of the load supporting member in the thickness direction. ### Claim 7 (depends on 2) The rope according to claim 2, wherein the cross members have a longitudinal-direction dimension which matches with a width-direction dimension of the load supporting member. ### Claim 8 (depends on 1) The rope according to claim 1, wherein the corrugated reinforcement fiber bodies are divided into a plurality of groups arrayed in a width direction of the load supporting member, and wherein the corrugated reinforcement fiber bodies in the groups adjacent to each other in the width direction of the load supporting member are deviated by 180° in phase in the longitudinal direction of the load supporting member. ### Claim 9 (depends on 1) An elevator, comprising: the rope of claim 1; a hoisting machine including a drive sheave having the rope wound therearound; and a car, which is suspended by the rope, and is configured to be raised and lowered through rotation of the drive sheave. ### Claim 10 (depends on 2) The rope according to claim 2, wherein the corrugated reinforcement fiber bodies are divided into a plurality of groups arrayed in a width direction of the load supporting member, and wherein the corrugated reinforcement fiber bodies in the groups adjacent to each other in the width direction of the load supporting member are deviated by 180° in phase in the longitudinal direction of the load supporting member. ### Claim 11 (depends on 2) An elevator, comprising: the rope of claim 2; a hoisting machine including a drive sheave having the rope wound therearound; and a car, which is suspended by the rope, and is configured to be raised and lowered through rotation of the drive sheave.
