A damper device including an input element to which a torque from an engine is transmitted; an output element; an elastic body to transmit torque between the input element and the output element; and rotary inertia mass damper having a mass body that rotates in accordance with a relative rotation of the input element and the output element. The output element is coupled to a rotor of an electric motor, which is coupled to an input shaft of a transmission. The rotary inertia mass damper includes a planetary gear mechanism having a carrier that supports pinion gears, the carrier is a part of the input element, one of the sun gear and the ring gear is a part of the output element, and the other of the sun gear and the ring gear functions as the mass body.
