A hoisting machine is interposed between a wall surface of a hoistway and a car when viewed in a horizontally-projected perspective, and a drive sheave is placed so as to oppose the wall of the hoistway. Vibration prevention members are provided between a mount member attached to the fixing members provided in the hoistway and upper and lower sections at surfaces of the mount member facing the hoisting machine, thereby supporting the hoisting machine on the mount member. As a result, required 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 a failure, and vibration and noise, which would arise during operation of an elevator of a building where the hoistway is installed, is reduced, thereby making an environment silent.
