PROBLEM TO BE SOLVED: To provide a fluid spring unit capable of being in a simple structure with fewer components, being simple for assembling, and preventing leakage of fluid from a connecting portion. SOLUTION: The fluid spring unit has an approximately disk-shaped body 10, and a pair of sandwiching plates 40 and 50 being opposite each other so as to sandwich the fluid spring body. A sealing structure of a connecting portion between base plate portions 41 and 51 and a side trunk 13 is improved on the fluid spring unit. The fluid spring unit comprises ring-shaped metal rings 25 and 35 substantially buried into elastic bases 21 and 31, and ring-shaped elastic seal members 27 and 37 extending toward an inward direction. The fluid spring body and the pair of the sandwiching plates are integrated only by being fitted to the center opening part of the fluid spring body. The side fitted to a fitting and projection part is urged by the ring-shaped elastic seal member of the fixing base part. COPYRIGHT: (C)2005,JPO&NCIPI
