DAMPER DEVICE AND STARTING DEVICE

摘要

A damper device includes a dynamic damper that has third springs coupled to an intermediate member and that also has, as a mass body coupled to the third springs, a turbine runner and a coupling member etc. The third springs of the dynamic damper are disposed so as to overlap both in the axial and radial directions of the damper device second springs that have higher rigidity than first springs and that are disposed inward of the first springs to transfer torque between a drive member and a driven member.

1. A damper device including an input element, an output element, first elastic bodies that transfer torque between the input element and the output element, and second elastic bodies that are disposed inward of the first elastic bodies to transfer the torque between the input element and the output element, wherein
the second elastic bodies have higher rigidity than the first elastic bodies, the damper device comprises a dynamic damper having third elastic bodies that are coupled to any of the rotary elements forming the damper device and a mass body that is coupled to the third elastic bodies, and the third elastic bodies are disposed so as to overlap the second elastic bodies both in axial and radial directions of the damper device.
