7, the mounting portions 19 corresponding to the supporting portions 12 of the mounting frame 8 and arranged below the supporting portion 12 are formed. Reference numeral 20 denotes an upper vibration isolator made of vibration isolating rubber interposed between the upper support portion 12 of the mounting frame 8 and the mounting portion 19 of the hoisting machine 16.

Reference numeral 21 is a lower vibration isolator made of vibration isolating rubber interposed between the lower support portion 12 of the attachment frame 8 and the attachment portion 19 of the hoisting machine 16, and 22 is wound around the drive sheave 18. Although not shown, one end of the main rope is wound around a pulley pivotally attached to the top of the hoistway 1 and connected to the car 3, and the other end is pivotally attached to the top of the hoistway 1. The drive sheave 18 is wound around a pulley and connected to a counterweight to apply an upward load to the drive sheave 18. Point B shown in FIG. 3 is the position of the center of gravity of the hoisting machine 16, and exists near the opposite wall surface of the hoistway 1 from the center of the rim width of the drive sheave 18.

In the hoisting machine for an elevator constructed as described above, the hoisting machine 16 is arranged between the wall surface of the hoistway 1 and the car 3 in the horizontal projection plane, and the side surface of the drive sheave 11 is the hoistway 1.
