According to one embodiment, a damper device includes a rotator, a first oscillator, a second oscillator, and two rollers, for example. The rotator is provided with a first opening. The second oscillator includes two guide surfaces recessed in a direction closer to a first center of rotation and a transmitting part capable of moving along the first opening. The two rollers each include a ring supported by the first oscillator and a shaft extending along a second center of rotation inside the ring and rotatably supported by the ring. The shaft comes into contact with a corresponding one of the two guide surfaces of the second oscillator pushed outward in the radial direction by centrifugal force, rolls along the corresponding one of the two guide surfaces by oscillation of the first oscillator, and is pushed by the corresponding one of the two guide surfaces in the circumferential direction.

Damper device

A damper device includes: a pressing plate; a rotation plate disposed to oppose the pressing plate; an elastic member elastically linking the pressing and rotation plates, and in which bending is generated when relative twist of the pressing and rotation plates is generated; and seats provided on both end surfaces of the elastic member The seat has a projected surface, the pressing plate has a recessed surface corresponding to the projected surface, the seats and the pressing plate come into surface-contact with each other in a case where the relative twist is not generated, one seat and the pressing plate come into surface-contact with each other, and a void is formed between the other seat and the pressing plate, in a case where the relative twist is generated, and the void increases as an angle of the relative twist increases.

In a damper device according to an embodiment, a third member is configured to be rotatable about a rotation center, rotate integrally with a first member in a first section, and rotate integrally with a second member in a second section. A first friction member has a first friction face that generates a friction torque along with relative rotation of the first member and the second member, and a second friction member has a second friction face that generates a friction torque along with relative rotation of the second member and the third member.

A torque fluctuation absorbing apparatus includes a hub member with a flange portion, first and second side-plates provided at both axial sides of the flange portion, respectively, a damper mechanism absorbing a fluctuation of a relative torque generated between the flange portion of the hub member and the first and second side-plates, a thrust member provided between the first side-plate and the flange portion of the hub member, and a first disc spring provided between the first side-plate and the thrust member and biasing the thrust member towards the flange portion of the hub member. The first side plate includes a bent portion bent towards the flange portion of the hub member and a bore formed at the bent portion, and the thrust member is formed with an engagement portion extending through the bore of the first side-plate and engaged with the bore of the first side-plate.
