PROBLEM TO BE SOLVED: To provide a pneumatic spring capable of easily performing a hook engaging work while a resilient mechanism is being provided with a hanging part for use in hanging operation and further capable of easily manufacturing the resilient mechanism.SOLUTION: This invention comprises: an upper face plate 1; a lower side member 2; and a cylindrical flexing member 3 placed between the upper face plate 1 and the lower side member 2. The lower side member has a resilient mechanism. The resilient mechanism 4 comprises: a top plate 9; a bottom plate 10; and a laminated resilient body 11 placed between the top plate 9 and the bottom plate 10. The laminated resilient body 11 is applied as a laminated structure in which intermediate plates 13 are held among a plurality of resilient layers 12 to be laminated. An outer circumferential end edge of at least one intermediate plate 13 among the intermediate plates 13 is provided with a hanging part 14.
【課題】弾性機構に吊上げ用の吊り部を設けつつ、フックの係止作業を容易に行なうことが可能で、かつ、弾性機構を容易に製造することが可能な空気ばねを提供することを目的とする。【解決手段】上面板1と、下側部材2と、上面板1及び下側部材2の間に介装される筒状の可撓部材3とを備え、前記下側部材は、弾性機構を有し、弾性機構4は、頂板9と、底板10と、頂板9及び底板10の間に介在させた積層弾性体11とを有し、積層弾性体11は、複数の弾性体層12の間に中間板13を挟み込んで積層した積層構造とされ、中間板13のうち、少なくとも1枚の中間板13の外周端縁に吊り部14が設けられた構成とする。【選択図】図1
