A flywheel device including driving and driven side flywheels, a first spring mechanism directly connecting the two flywheels with a predetermined torsional angular gap, and a second spring mechanism provided in parallel to the first spring mechanism and connecting the two flywheels via a friction mechanism provided in series with the second spring mechanism. The flywheel device has two vibrational characteristics between which the flywheel device changes its vibrational behavior while passing through the resonance speed to suppress amplification in vibration. The friction mechanism slips momentarily only while passing through the resonance speed and does not slip at a standard range of engine speeds. Due to the lack of slippage of the friction mechanism at the standard range of engine speeds, the torque variation absorbing effect of the flywheel device is greatly improved.
