ABSTRACT OF THE DISCLOSURE An elevator drive apparatus comprising a motor and reduction gear unit resiliently mounted on a first support member via vibration isolators, and a traction sheave rotatably mounted on a second support member via a bed member and vibration isolators. An output shaft of the reduction gear unit is connected to the sheave by an elastic coupling. The vibration isolators and the elastic coupling isolate vibrations generated by the engagement between the teeth of the reduction gears and by the pulsating rotation of the drive motor and reducing such vibrations from the sheave, which improves the ride comfort in the elevator cage.
