PROBLEM TO BE SOLVED: To provide an air spring capable of more surely securing airtightness of a diaphragm while suppressing an increase in weight.SOLUTION: An air spring 1 includes an upper face plate, a lower face plate and a diaphragm 50 connecting the upper face plate and the lower face plate. The diaphragm 50 has an annular cylindrical shape in which an opening is formed on an inner peripheral side. In the diaphragm 50, an upper face plate contact section 52 which defines the opening and is a region in contact with the upper face plate includes a deformation section 56 which is elastically deformed so as to project to the lower face plate side by being brought into contact with a support plate 11. The deformation section 56 is in contact with a slide member 12 positioned on the lower face side when viewed from the deformation section 56. |
