    摘要: When “It” is defined as the moment of inertia of all elements included in a torque transmission path from a front cover 3 to a damper hub 7, “Im” is defined as the moment of inertia of a first intermediate member 12 coupled to a vibration absorption spring Spd of a dynamic damper 20, “Idd” is defined as the moment of inertia of a mass body of the dynamic damper 20, “A=Im/It”, “B=Idd/Im”, and “Netag” is defined as a rotation speed of an engine corresponding to a frequency of vibration to be damped by the dynamic damper, the starting device is configured so as to satisfy 0.04≦A≦0.10, 0.90≦B≦2.60 and 900 rpm≦Netag≦1400 rpm.
