DAMPER DEVICE AND STARTING DEVICE

摘要

A damper device of a starting device includes a drive member, a driven member, outer springs that transmit torque between the drive member and the driven member, first and second inner springs that are placed inward of the outer springs and that transmit torque between the drive member and the driven member, and a dynamic damper having third springs coupled to a first intermediate member as a rotary element and a turbine runner as a mass body coupled to the third springs. The third springs of the dynamic damper are disposed so as to be located next to the outer springs of the damper device in the circumferential direction.

1. A damper device including an input element, an output element, an outer elastic body that transmits torque between the input element and the output element, and an inner elastic body that is disposed inward of the outer elastic body and that transmits torque between the input element and the output element, comprising:
a dynamic damper that has a third elastic body coupled to any one of rotary elements forming the damper device and a mass body coupled to the third elastic body, and that applies vibration of an opposite phase to the rotary element to dampen vibration, wherein the third elastic body is disposed so as to be located next to the outer elastic body in a circumferential direction.
