A wheel load adjusting apparatus used in a railcar, and the railcar includes: first and second air springs arranged between a carbody and a first bogie so as to be spaced apart from each other in a car width direction; third and fourth air springs arranged between the carbody and a second bogie so as to be spaced apart from each other in the car width direction; and first to fourth automatic level controlling valves provided upstream of the first four air springs and configured to adjust heights of the four air springs to maintain constant height of the air springs, wherein when the railcar passes through a curve, the wheel load adjusting apparatus limits an air supply/air discharge operation of at least one of the four automatic level controlling valves to suppress an increase in a pressure difference between at least two of the four air springs.
