Abstract
Rubber vibration isolators are held between a base frame supporting a driving device and an upper deflecting sheave, and a support connected to car guide rails and a counterweight guide rail. The rubber vibration isolators are held between a horizontal member and vertical members of a support frame supporting lower deflecting sheaves. Transmission of vibrations generated by the driving device, the upper deflecting sheave, and the lower deflecting sheaves to the side walls of an elevator shaft can be intercepted.
