To reduce influences upon a vibration absorption performance of a damper caused by centering fluctuation of a vibration absorber part in the damper of a torque converter.SOLUTION: A damper comprises: an input rotation member which performs torque transmission in the case of lock-up; an output rotation member for transmitting a torque to a rotary output shaft; an intermediate rotation member which is interposed between the input rotation member and the output rotation member; a first elastic member which is interposed between the input rotation member and the intermediate rotation member; a second elastic member which is interposed between the intermediate rotation member and the output rotation member; a vibration absorber part which is mounted in the intermediate rotation member; and a first centering part which is interposed between the intermediate rotation member and the output rotation member and in which a centering surface formed in the intermediate rotation member and a centering surface formed in the output rotation member are slid.SELECTED DRAWING: Figure 2 【課題】 トルクコンバータのダンパにおいて振動吸振子部のセンタリング変動によるダンパの吸振性能への影響を低減する。【解決手段】 ロックアップするときにトルク伝達する入力回転部材と、回転出力軸にトルクを伝達するための出力回転部材と、前記入力回転部材と前記出力回転部材との間に介在する中間回転部材と、前記入力回転部材と前記中間回転部材との間に介在する第１の弾性部材と、前記中間回転部材と前記出力回転部材との間に介在する第２の弾性部材と、前記中間回転部材に取り付けられた振動吸振子部と、前記中間回転部材と前記出力回転部材との間に介在し、前記中間回転部材に形成されたセンタリング面と前記出力回転部材に形成されたセンタリング面とが摺動する第１のセンタリング部とを備えた。【選択図】図２
