Damper device

A damper device comprising:

• an input element;
• a first intermediate element;
• a second intermediate element;
• an output element;
• a plurality of first elastic bodies that transmits torque between the input element and the first intermediate element;
• a plurality of second elastic bodies that transmits torque between the first intermediate element and the second intermediate element;
• a plurality of third elastic bodies that acts in series with the second elastic bodies and transmits torque between the second intermediate element and the output element;
• and
• a dynamic damper that includes a mass body and vibration absorbing elastic bodies, wherein
• the vibration absorbing elastic bodies of the dynamic damper are directly coupled to the first intermediate element;
• the second elastic bodies are straight coil springs disposed between the first intermediate element and the second intermediate element and the third elastic bodies are straight coil springs disposed between the second intermediate element and the output element so that outward movement of the second and the third elastic bodies in a radial direction of the damper device is restricted at respective both end portions;
• and
• a gap is formed between each body portion of the second and the third elastic bodies and a corresponding one of the second intermediate element and the output element disposed on an outer side of each of the second and the third elastic bodies in the radial direction,
• wherein damper device is configured so that torque is transferred in an order such that the torque is transferred from the input element to the first intermediate element, the torque transferred to the first intermediate element is then transferred to the second intermediate element, and then the torque transferred to the second intermediate element is transferred to the output element.
