Abstract
A damper device includes a damper device body, an output shaft and a dynamic vibration absorber. The damper device body includes an input member and an output member. The input member and the output member are coupled to be rotatable relative to each other. The output shaft outputs a torque transmitted to it from the damper device body. The dynamic vibration absorber is attached to the output shaft.
Claims6
A damper device comprising:
- a damper device body including an input member and an output member, the input member and the output member coupled to be rotatable relative to each other;
- an output shaft configured to output a torque transmitted thereto from the damper device body;
- and
- a dynamic vibration absorber attached to the output shaft,
- the dynamic vibration absorber including a base member and a mass body, the base member attached to the output shaft, the mass body disposed to be rotatable relative to the base member,
- the dynamic vibration absorber further including
- a centrifugal element disposed to receive a centrifugal force generated by rotation of the output shaft, and
- a cam mechanism configured to convert the centrifugal force acting on the centrifugal element into a circumferential force.
