Abstract
The present invention relates to a wheelchair of a bus, which is constructed from plates such as metal sheets connected with hinges and from power supplying devices such as hydraulic cylinders. Some of the power supplying devices work to fold and unfold the plates, and the other power supplying device works to lift up and down the plates. When the plates are folded, they form stairs that enable passengers to easily get on and off the bus. When the plates are unfolded, they form a lift which enables handicapped passengers in wheelchairs to get on and off the bus by the power supplying device.
