Abstract
When 'It' is defined as the moment of inertia of all elements included in a torque transmission path from a front coverto a damper hub, 'Im' is defined as the moment of inertia of a first intermediate membercoupled to a vibration absorption spring Spd of a dynamic damper, “Idd” is defined as the moment of inertia of a mass body of the dynamic damper, “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.
