PURPOSE:To make improvement in controllability and safety as well as to check any possible degradation in an elastic member by forming an extension in a retainer, and interposing the elastic member between this extension and piston rod as well as between a canister and the retainer, respectively. CONSTITUTION:A cylindrical member 22 is attached to the outer circumference of a buffer body 20, and an air spring chamber 25 is formed by this cylindrical member 22, a rubber tube 23 and a canister 24. In addition, a cylindrical extension 30 is formed in a retainer 29 being clamped to a car body 28 by a bolt 27, and a first elastic member 32 is installed in space between this extension 30 and a cylindrical elastic member supporter 31 being fitted in a piston rod 21. Moreover, a second elastic member 33 is installed in space between a top face of the canister 24 and the retainer 29. The first elastic member 32 compresses cross and longitudinal force from the axle side, checking the displacement and improving safety or the like, and since the displacement is less, degradation in the elastic member is also checkable. |
