<p>PURPOSE:To effectively prevent secular fatigue and deformation of a joint between a bellows tube and a bellows plate and pipe ends due to vibration and improve fluid leakage preventive effect by well absorbing the vibration of the pipe with an air damping chamber and an elastic body to reduce load on the bellows tube and the bellows plate so that fluid shut-off effect can be satisfactorily shown. CONSTITUTION:A first pipe end 11 and a second pipe end 12 are jointed via a bellows tube 13, an air damping chamber is formed to encircle the outer periphery of the bellows tube 13 and a joint between the tube and both pipe ends 11, 12 and a housing 15 with the air damping chamber partitioned is provided with an elastic body 16 to elastically combine the first pipe end 11 and the second pipe end 12.</p> |
