PROBLEM TO BE SOLVED: To provide a vibration-proof structure for an elevator capable of enhancing vibration-proofing performance without changing the structure at a large scale. SOLUTION: In the vibration-proof structure for reducing transmission of vibration to a building side by supporting a vibration generation source 16 for generating vibration accompanying with lifting of a car 11 through elastic bodies 41, 42, the elastic body is made to the one in which a first elastic body 41 and a second elastic body 42 having different kinds are arranged in parallel. While ensuring load-resistant property by making spring constant of the first elastic body high, transmission of vibration from the vibration generation source to the support means can be reduced by making spring constant of the second elastic body low.
