PROBLEM TO BE SOLVED: To provide a torque converter including a damper mechanism which exerts attenuation performance in a wide frequency band without increasing the size of a device.SOLUTION: A torque converter 10 includes: a pump impeller 11; a turbine impeller 12; a lock-up clutch 20; and an output member 30 connected to an output shaft. It also includes: a plurality of primary springs 28 attached to the lock-up clutch 20; a plurality of secondary springs 38 attached to the output member 30; and an intermediate member 40 for holding the output member 30 and disposed between the primary springs 28 and the secondary springs 38 connected in series. At the intermediate member 40, a first dynamic vibration absorber 50 including a first mass body 51 and a first damper member 58 and a second dynamic vibration absorber 60 including a second mass body 61 and a second damper member 68 are attached. The set frequencies of the first dynamic vibration absorber 50 and the second dynamic vibration absorber 60 are different from each other.SELECTED DRAWING: Figure 1 【課題】装置を大型化させることなく広い周波数帯において減衰性能を発揮するダンパ機構を具備するトルクコンバータを提供する。【解決手段】ポンプ羽根車１１と、タービン羽根車１２と、ロックアップクラッチ２０と、出力軸に連結される出力部材３０とを有するトルクコンバータ１０において、ロックアップクラッチ２０に付帯される複数の一次スプリング２８と、出力部材３０に付帯される複数の二次スプリング３８と、出力部材３０を保持するとともに直列に連結される一次スプリング２８と二次スプリング３８との間に配設される中間部材４０と、を有し、中間部材４０には、第一質量体５１と第一ダンパ部材５８とを具備する第一動吸振器５０と、第二質量体６１と第二ダンパ部材６８とを具備する第二動吸振器６０とが付帯され、第一動吸振器５０と第二動吸振器６０とは、互いに設定周波数が異なることを特徴とする。【選択図】図１
