PURPOSE: A swing door of a super low floor bus is provided to prevent the external air from being inserted into the inside by restricting excessive strain of a brush installed at the lower part of the door. CONSTITUTION: A swing door(50) of a super low floor bus is composed of a brush contacted with a floor mounted in a bus room and lowered gradually toward the outside, and installed on the bottom side of the swing door to shield the inside of the bus from the outside; a rotary shaft(H) disposed at a bus body to rotate the door and lifted at predetermined degree from the bus body; a piston(1) mounted on the bottom side of the rotary shaft to lift the rotary shaft; and a driving unit for moving down the swing door in closing the door and moving up the swing door in opening the door by inserting/exhausting high-pressure air into/from the piston.
