PROBLEM TO BE SOLVED: To improve the durability of a bearing mechanism while maintaining the durability of a diaphragm. SOLUTION: An absorber 10 generates damping force with the movement of a cylinder 11 relative to a piston rod 12 in the axial direction of the absorber. An air spring 20 has a piston 21 forming an air chamber R, a chamber 22, and the diaphragm 23. The piston 21 is installed on the outer periphery of the cylinder 11 via the bearing mechanism 31 and a bellows 32 with air tightness so that it is moved integrally with the cylinder 11 in the axial direction of the absorber. The chamber 22 is arranged on the outer periphery of the piston rod 12 so that it is moved integrally with the piston rod 12 in the axial direction of the absorber. The diaphragm 23 is installed between the chamber 22 and the piston 21. The bearing mechanism 31 in the state of being sealed by the bellows 32 allows the rotation of the cylinder 11 relative to the piston 21 around the axis of the absorber.
