  • Damper device
    Patent number: 10711862
    Abstract: A damper device that includes an elastic body support provided to the intermediate element to support both end portions of the third elastic body at least when torque is not transferred between the input and the output; and an elastic body abutment provided to one of the input and the output, the elastic body abutment not abutting against an end portion of the third elastic body at least when torque is not transferred between the input and the output, but abutting against one of the end portions of the third elastic body as a relative torsional angle between the one of the input and the output and the intermediate element is increased when torque is transferred between the input and the output.
