<P>PROBLEM TO BE SOLVED: To provide an air spring capable of ensuring airtightness without complicating the structure. <P>SOLUTION: The air spring includes: an upper-surface plate 1; a lower-surface plate 2; a cylindrical flexible member 3 disposed between the upper-surface plate 1 and the lower-surface plate 2; and an elastic stopper 4 attached to the lower-surface plate 2. The lower-surface plate 2 has: a bead receiving part 8, into which the bead part 3b of the lower end part of the flexible member 3 is fitted; and a flange part 9 formed on the outer side in the radial direction from the bead receiving part 8. A through-hole 15 is formed on the flange part 9, a fixing member is engaged with the through-hole 15, and the lower-surface plate 2 and a top plate 13 of the elastic stopper 4 are fixed to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
