  "textContent": "A variable load valve (21) comprises: a pressure regulating valve (50) capable of outputting a pressure corresponding to a full-load-condition load compensating pressure; a pilot pressure sensor (52b); a solenoid valve (52) capable of charging/discharging air pressure, and operable, in accordance with a detection value from the pilot pressure sensor (52b), to adjust the pressure output from the pressure regulating valve (50) by means of the charging/discharging, and output the resulting pressure; and an output valve (51) adapted to receive an input of the pressure output from the solenoid valve (52), as a pilot pressure. The output valve (51) has an empty-condition assuring spring (51d) for generating a pressure corresponding to an empty-condition load compensating pressure. The output valve (51) is capable of outputting a pressure obtained by adding the pilot pressure and a pressure corresponding to the empty-condition load compensating pressure based on a biasing force of the empty-condition assuring spring (51d), as a load compensating pressure according to a detection value from a sensor operable to detect an air spring pressure.",
