Damper device

A damper device comprising:

• a rotator capable of rotating about a first center of rotation and provided with at least one first opening;
• a first oscillator capable of oscillating about the first center of rotation with respect to the rotator;
• at least one second oscillator including two guide surfaces recessed in a direction closer to the first center of rotation and at least one transmitting part capable of being supported by an edge of the first opening in a circumferential direction of the first center of rotation and capable of moving along the first opening, the second oscillator capable of oscillating in a radial direction of the first center of rotation with respect to the rotator;
• and
• two rollers that extend along a second center of rotation and at least part of which is supported by the first oscillator rotatably about the second center of rotation, the rollers being configured to come into contact with the respective two guide surfaces of the second oscillator pushed outward in the radial direction of the first center of rotation by centrifugal force generated by rotation of the rotator, and configured to roll along the respective two guide surfaces by oscillation of the first oscillator with respect to the rotator and to be pushed by the respective two guide surfaces in the circumferential direction of the first center of rotation, wherein
• the second oscillator is capable of translation in the radial direction of the first center of rotation with the two guide surfaces supported by the respective two rollers.
