ばね。An air spring bellows is arranged between a load-bearing seat and a base to form a sealed container, and pressurized air in the sealed container is discharged to the outside or pressurized air is allowed to flow into the sealed container. A first valve mechanism is disposed in the sealed container, and the valve mechanism includes an actuation member that moves in accordance with fluctuations of the air spring bellows, and an air supply valve and an outflow valve that are displaced by the movement of the actuation member.
, an arm and a second arm.The upper end of the actuating member is fixed to a seat, and the lower bent piece of the actuating member is fixed to the first arm.
An air spring characterized in that the arm is provided with an upper bent piece so as to close or open the exhaust hole and the air supply hole by respectively engaging or disengaging the upper bent piece with the second arm.
