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 toward the first center of rotation and at least one transmitting part capable of being supported by an edge of the at least one first opening in a circumferential direction of the first center of rotation and capable of moving along the at least one first opening, the at least one second oscillator capable of oscillating in a radial direction of the first center of rotation with respect to the rotator;
• and
• two rollers each including a ring supported by the first oscillator and a shaft extending along a second center of rotation inside the ring and supported by the ring rotatably about the second center of rotation with respect to the first oscillator, the shaft coming into contact with a corresponding one of the two guide surfaces of the at least one second oscillator pushed outward in the radial direction of the first center of rotation by centrifugal force generated by rotation of the rotator, rolling along the corresponding one of the two guide surfaces by oscillation of the first oscillator with respect to the rotator, and being pushed by the corresponding one of the two guide surfaces in the circumferential direction of the first center of rotation.
