PROBLEM TO BE SOLVED: To provide a joint structure of an air spring which enables easy maintenance.SOLUTION: A joint structure of an air spring is used to join a link arm 12 to an air spring 20. The air spring 20 has: a contractible bellows 21 forming an air chamber; a seat part 23 provided at one end side of the bellows 21; and a shaft part 24 provided at the seat part 23 and extending in a contraction direction of the bellows 21. A through hole 121 into which the shaft part 24 of the air spring 20 is inserted is formed at the link arm 12, and a female screw part 231 is formed at the seat part 23. The shaft part 24 has: a male screw part 30 which is threadedly engaged with a female screw part 231; and a shaft part main body 31 having an outer diameter larger than that of the male screw part 30.SELECTED DRAWING: Figure 3

    【課題】メンテナンス容易なエアスプリングの接合構造を提供すること。【解決手段】エアスプリングの接合構造は、エアスプリング20のリンクアーム12との接合構造である。エアスプリング20は、空気室を形成して収縮可能なベローズ21と、ベローズ21の一端側に設けられた着座部23と、着座部23に設けられてベローズ21の収縮方向に延びる軸部24と、を有する。リンクアーム12には、エアスプリング20の軸部24が挿通される貫通孔121が形成され、着座部23には、雌ねじ部231が形成されている。軸部24は、雌ねじ部231に螺合される雄ねじ部30と、雄ねじ部30よりも外径が大きい軸部本体31と、を有する。【選択図】図3
