Abstract

　ダンパ１は、容器２と、容器２内を粘性流体３を収容する二つの収容室４及び５に区画すると共に容器２と共にＲ方向に回転する軸方向Ａに可動な区画部材６と、転Ｒ１方向の回転入力により区画部材６にＡ１方向への移動力を与える移動力付与手段７と、区画部材６をＡ２方向に弾性的に付勢する弾性手段８と、容器２内の二つの収容室４及び５を相互に連通する貫通孔９と、容器２内の二つの収容室４及び５に収容された粘性流体３の貫通孔９を介する二つの収容室４及び５間の相互の流動を許容すると共にＡ１方向への区画部材６の移動に基づくＡ１方向における収容室４に収容された粘性流体３の一定値を超える内圧の発生では貫通孔９を介する収容室４の粘性流体３のＡ２方向における収容室５への流動を制限する許容・制限部材１０とを具備している。
