(54) VEHICULAR DAMPER DEVICE


(57) Providing a vehicular damper device capable of achieving a high damping effect, without an increase of vibration transmission sensitivity at frequencies other than the natural frequency.
A dynamic damper 120 is constituted by a second flywheel 54, and a D/D spring device 56 operatively connecting the second flywheel 54 to a first flywheel 50. The first flywheel 50, which is disposed on the side of an engine 24, is considered to be connected to a structural body having a larger inertia mass, than where the first flywheel 50 was disposed on the side of an output shaft 39. Namely, the first flywheel 50 is a part of a structural body which includes the engine 24 and which has a large inertia mass. Since the dynamic damper 120 is connected to the first flywheel 50 which is a part of the structural body having the large inertia mass, the dynamic damper 120 achieves a high damping effect.
