ABSTRACT:
A hoisting machine is interposed between a wall of a hoistway and a car when viewed in a horizontally-projected perspective, and a drive sheave is located opposite the wall of the hoistway. Vibration prevention members are located between the hoisting machine and a mount member attached to fixing members in the hoistway. The vibration prevention members are located at surfaces of upper and lower portions of the mount member facing the hoisting machine, supporting the hoisting machine on the mount member from underside. As a result, vibration control of the hoisting machine can be readily achieved, and the torque acting on the hoisting machine is supported by horizontal rigidity of the vibration prevention member. Consequently, the hoisting machine can be attached to the mount member without failure. Vibration and noise, which would arise during operation of an elevator in a hoistway of a building, is reduced, thereby making the environment of the elevator silent.
