    Abstract: A damper device includes an input element to which a torque from an engine is transmitted; an intermediate element; an output element; a first elastic body that transmits a torque between the input element and the intermediate element; a second elastic body that transmits a torque between the intermediate element and the output element; a rotary inertia mass damper that includes a first mass body rotating in accordance with relative rotation between the input element and the output element and that is arranged between the input element and the output element to be parallel to a torque transmission path including the first elastic body, the intermediate element and the second elastic body; a second mass body; and an elastic body arranged to couple the second mass body with the output element.

    Abstract: An intermediate member includes first and second intermediate members. The first and the second intermediate members are provided with a spring supporting portion that extends along springs and supports the springs from an outer side. An expansion and contraction of the springs enables the intermediate member to be movable in a circumferential direction. Accordingly, sliding distances caused by the expansion and contraction of the first and the second springs become shorter, compared with a configuration where the first and the second spring are supported by the driven member or drive member from the outer side, thereby decreasing an energy loss (hysteresis) caused by the sliding. As a result, a vibration damping performance of the damper device can be improved.

    Abstract: A damper device includes rotating elements including an input element and an output element, first elastic bodies that each transmit torque between the input element and the output element, a plurality of second elastic bodies that act in parallel with the plurality of first elastic bodies when torque transmitted between the input element and the output element is greater than or equal to a predetermined value, and a rotary inertia mass damper. The rotary inertia mass damper includes a sun gear, a carrier that rotatably supports a plurality of pinion gears, and a ring gear that meshes with the plurality of pinion gears and that serves as a mass body. The plurality of second elastic bodies are located at a different position than the plurality of first elastic bodies in a radial direction of the rotating elements and are circumferentially aligned with the plurality of pinion gears.
