<p>PROBLEM TO BE SOLVED: To provide a bellows having high internal pressure resistance and excellent in stress absorption. SOLUTION: A reinforcement ring 20 is arranged on the outer circumference of each small diameter part 12 of a bellows body 10 in which a large diameter part 11 and a small diameter part 12 are formed in an alternate and continuous tubular shape, and a connection member 13 is provided on each end, and a plurality of vibration suppression mechanisms 30 are provided at equal intervals in the circumferential direction on its outside. In the vibration suppression mechanisms 30, connection rods 31 arranged on the outer circumferential side corresponding to each reinforcement ring are connected to each other through a thrust damper, the connection rod 31 at each end is connected to a flange 13B of the connection member 13 through a thrust damper 32, and each reinforcement annular ring 20 is connected to the corresponding connection rod 31 through a radial damper 33.</p> |
