Abstract
A vibration damping device including: a support member rotating with a rotary element to which torque from an engine is transferred about the center of rotation of the rotary element; a restoring force generation member coupled to the support member and swingable with rotation of the support member; and an inertial mass body coupled to the support member via the restoring force generation member and swung about the center of rotation in conjunction with the restoring force generation member with rotation of the support member. The order of the vibration damping device is larger than the sum of the excitation order of the engine and an offset value determined in consideration of the effect of oil in the oil chamber. The reference order, which is a convergent value of the order of the vibration damping device, is higher than the excitation order.
