PROBLEM TO BE SOLVED: To provide an air spring capable of moderating a contact condition between a diaphragm constituting an air spring for a bolsterless bogie of a rolling stock and a rubber-made member of an outer cylinder or an inner cylinder, reducing abrasion quantity of rubber, and extending a life against abrasion of the diaphragm or the rubber-made member. SOLUTION: This air spring 1 for the bolsterless bogie of the rolling stock comprises the diaphragm 2 and a rubber seat 8 that contacts with the diaphragm 2 to support the diaphragm 2. The rubber seat 8 comprises the rubber-made member 7 contacting with the diaphragm 2 and a backing 8 for supporting the rubber-made member 7. The backing 8 is formed so as to be vertical to the contact surface of the rubber-made member 7 with the diaphragm 2 and a support surface for supporting the rubber-made member 7 is substantially vertical.
