Abstract: A drive member of a damper device includes a first input plate member and a second input plate member that rotatably support a plurality of pinion gears of a planetary gear of a rotary inertia mass damper. A driven member includes an outer teeth gear portion that meshes with the pinion gear in an outer circumferential portion thereof and is disposed between the first and the second input plate members in an axial direction so as to work as a sun gear of the planetary gear. A stopper is configured to restrict the relative rotation between the drive member and the driven member and includes a contact portion arranged in the outer circumferential portion of the driven member so as to contact with the first input plate member.

Abstract: An intermediate member is configured to include first and second intermediate members. Connecting portions that respectively extend outward from the first or the second intermediate plates are coupled with each other at two positions on the same circumference as pinion gears by two rivets (total six rivets at three connecting portions) as viewed in a central axis of the damper device. Such an arrangement enables spaces between the pinion gears to be used effectively, increases spaces for the first spring, the second spring and the inner spring and improves a vibration damping performance of a damper device.

Abstract: A damper device includes first inner springs configured to transmit a torque between a drive member and an intermediate member, second inner springs configured to transmit a torque between the intermediate member and a driven member, and a rotary inertia mass damper including a sun gear serving as a mass body rotating with relative rotation of the drive member to the driven member. The rotary inertia mass damper is provided in parallel to a torque transmission path including the intermediate member, the first inner springs and the second inner springs. A damping ratio ζ of the intermediate member determined based on a moment of inertia J2 of the intermediate member and rigidities k1 and k2 of the first and the second inner springs and is less than a value.

Abstract: A washer having such a thickness t that a value (L3−(L1+L2+t)) obtained by subtracting the sum of a first distance L1 in an axial direction between a leading end face of a friction member and a face of a lockup piston, a second distance L2 in the axial direction between a shell-side abutting face of a pump shell and a face of an outside extended portion of an output hub, and the thickness t in the axial direction of the washer, from a third distance L3 in the axial direction between an opposed face of a front cover and a cover-side abutting face of a tubular portion, is in a predetermined range larger than zero, is selected and placed between the lockup piston and the outside extended portion of the output hub.

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: Six through holes are formed in pinion gear supporting portions of two input plate members working as a carrier that supports pinion gears of a rotary inertia mass damper. The two input plate members are opposed to each other in such a manner that the through holes are aligned with each other. The through holes support the pinion gear. The input plate members are coupled with each other by means of rivets passing through the through holes located on both sides of the through holes. This configuration ensures strength (rigidity) of the carrier, suppresses deformation of a planetary gear, and improves meshing accuracy of gears.
