PROBLEM TO BE SOLVED: To provide a viscous fluid-filled damper with a stirring cylinder portion hard to break by making a mounting shaft hard to extract from the stirring cylinder portion without impairing vibration damping performance. SOLUTION: A hard wall portion 15 is provided on the stirring cylinder portion 12 of the viscous fluid filled damper and the thickness of a rubber elastic body constituting the stirring cylinder portion 12 in an area on the hard wall portion 15 is reduced. Thus, when the mounting shaft 9 is moved in the direction of extraction, an engagement head portion 9a is hitched thereon for locking it with strong holding force. COPYRIGHT: (C)2007,JPO&INPIT |
