Abstract
A damperincludes a vessel; a partitioning memberwhich partitions an internal space of the vesselinto two accommodation chambersandfor accommodating a viscous fluidand which is movable with respect to the vessel; a moving force imparting devicefor imparting to the partitioning membera moving force in an Adirection by the input of rotation in an Rdirection with respect to the vessel, so that the moving velocity is set to one corresponding to the rotating velocity of that input of rotation; a resilient devicefor resiliently urging the partitioning memberin an Adirection; a communicating holeformed in the partitioning member; and a flow limiting devicefor limiting the flow of the viscous fluidin the accommodating chamberinto the accommodating chamberthrough the communicating holewhen the internal pressure of the viscous fluidaccommodated in the accommodating chamberhas exceeded a fixed value.
