Claims

[Claims for Utility Model Registration] An annular shape that is directly or indirectly attached to a predetermined rotating shaft and is located concentrically outside the rotating shaft inside a case member that is rotated together with the rotating shaft. A viscous fluid-filled damper comprising: a mass storage chamber, an annular mass member movably housed and arranged in the mass storage chamber, and a predetermined high viscosity fluid sealed in the mass storage chamber; A plurality of protrusions that protrude in the axial direction or radial direction are independently provided in the circumferential direction on the mass member, and each of the protrusions is inserted into the mass housing chamber, and the protrusions are inserted into the mass storage chamber. By providing a recess that forms a gap of a predetermined size around the recess, a vibration acting part with a predetermined gap is formed between the circumferentially opposing surfaces of the protrusion and the inner surface of the recess within the recess. A characteristic viscous fluid-filled damper.
