Abstract
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.
