Abstract:
1. A vehicle damper device disposed between a power transmission member coupled to an output shaft of an engine and a power transmission shaft disposed concentrically and rotatably relative to the power transmission member, the vehicle damper device comprising: an input-side rotating member to which power of the engine is input via the power transmission member; an output-side rotating member relatively non-rotatably coupled to the power transmission shaft to be concentric and rotatable relative to the input-side rotating member; a mass body disposed rotatably relative to the input-side rotating member; a first elastic member interposed between the input-side rotating member and the mass body, the first elastic member operatively coupling the input-side rotating member and the mass body while elastically deforming depending on a relative rotation amount between the input-side rotating member and the mass body; and a second elastic member interposed between the input-side rotating member and the output-side rotating member, the second elastic member operatively coupling the input-side rotating member and the output-side rotating member while elastically deforming depending on a relative rotation amount between the input-side rotating member and the output-side rotating member, wherein the first elastic member and the second elastic member are made up of coil springs, the first elastic member is disposed on an outer circumferential side relative to the second elastic member, and the damper device is disposed at a position axially separated by a predetermined value from the power transmission member, and the mass body is disposed on the outer circumferential side relative to the first elastic member.
