An air spring for vehicles is provided to change the spring properties of an air spring, thereby improving ride comfort according to rolling. An air spring for vehicles comprises: a tube line(100) whose both ends are connected to right and left air springs installed on a vehicle body; and a adjusting valve(200) installed on the route of the tube line. The adjusting valve blocks air inflow of the tube line in case of rolling side to side in order to change the spring properties of the air spring. The adjusting valve is installed in the middle of the tube line. The adjusting valve consists of: a valve body(210) having a through-hole(212) to be connected to the tube line; a chamber(220) positioned above the through-hole; and a central weight(230) combined with the valve body.
