PURPOSE: A rope-less elevator is provided to prevent the generation of vibration in a lift process and enhance riding comfort and stability by lifting a lift unit with air pressure. CONSTITUTION: A rope-less elevator comprises a lift path(10), a lift unit(20), an air pressure control unit(30), a support. The inside of the lift path is air-tight. The lift unit lifts along the lift path in a state of blocking air between upper and lower parts. The air pressure control unit controls the air pressure of the upper and lower parts of the lift unit and lifts the lift unit by pressure difference. The support is installed on the lower part of each floor and is protruded to the lift path at the time of lift unit stopping to support the lift unit.
