Vehicle damper device

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.
