To provide a leveling device for an elevator suppressing level difference of a car floor 7 and a landing place of each story 11 to a predetermined allowance range even when a car load Lw is fluctuated.

The car load Lw when a vibration proof rubber 6 for supporting the car floor 7 is compressed by the car load Lw and the level difference of the car floor 7 and the landing place of each story 11 is in the allowance range is recorded in a reference load record means as a reference load and it is controlled such that the vibration proof rubber 6 becomes the compression state by the reference load by operating a car floor driving means 15 based on difference of a measurement value of a weighing machine 9 for measuring the car load Lw and the reference load to vertically move the car floor 7.
