PROBLEM TO BE SOLVED: To provide a pneumatic spring system for a vehicle, which can continuously change a communicating amount of fluid between a pneumatic spring and an auxiliary tank according to a situation of vibration. SOLUTION: A pneumatic spring system 201 for the vehicle includes a pneumatic spring part 208 provided between a vehicle body 202 and a carriage 204, an auxiliary tank part 210 provided to the carriage 204 or the vehicle body 202, and a variable choke device 16 provided to a communicating part communicating the pneumatic spring part 208 and the auxiliary tank part 210. The variable choke device 16 linearly or nonlinearly changes the communicating amount between the pneumatic spring part 208 and the auxiliary tank part 210 according to a relative displacement difference of a swing spool 50 with respect to a sleeve 40, regardless of a sign of the relative displacement difference of the swing spool 50 with respect to the sleeve 40.
