  • Patent number: 10589962
    Abstract: In an elevator hoisting machine mounting device, an elastic support device includes a supporting elastic body that deforms elastically upon reception of a load from a hoisting machine unit. A buckling suppression device disposed at a remove from the elastic support device in a horizontal direction includes first and second buckling suppression elastic bodies that sandwich, from above and below, a buckling suppression attachment portion provided on a lower portion of the hoisting machine unit, and a holding tool that holds the first and second buckling suppression elastic bodies on a machine base. The buckling suppression device suppresses, by an elastic restoring force of the first and second buckling suppression elastic bodies, buckling of the hoisting machine unit relative to the machine base due to the elastic deformation of the supporting elastic body.
