A wheelchair elevator includes a base, a support frame, and a movable flat. The support frame is positioned on the base, consisting of two X-shaped frames, and the movable flat is fixed on the support frame, having a receptive base respectively at two lengthwise sides a little lower than the flat. The receptive base has a lengthwise wheel passageway and a stopper behind the passageway. The flat with the support frame is raised up or lowered down by a shrinkable air tube pumped by a swing rod. Then wheelchair can be pushed on the two wheel passageways of the receptive base and stopped by the stoppers, and then the flat with the support frame is raised by pumping air into the shrinkable air tube to a needed height for boarding in a vehicle or lowered down from the vehicle.
