Provided is a damper device which is configured so that coiled springs and the eaves sections of spring seats have improved durability despite the fact that the eaves sections are adapted to be deformable, following the deformation of the coiled spring. A damper device is characterized in that the damper device comprises: first coiled springs (31) and second coiled springs (32), the first and second coiled springs (31, 32) being circumferentially arranged between the hub plate-side support arms (11) of a hub plate (1) and the intermediate plate-side support arms (24) of an input and output plate (2); and resinous first spring seats (41) and resinous second spring seats (42), the first and second spring seats (41, 42) being configured in such a manner that each of the first spring seats (41) and the corresponding one of the second spring seats (42) support the opposite ends of each of the first and second coiled springs (31, 32), the first and second spring seats (41, 42) each having a metallic core member (45) provided therein. The damper device is also characterized in that: the spring seats (41, 42) each have a seating section (43) and an eaves section (44); and the metallic core member (45) has an eaves-section metallic core member (452) having a low-rigidity section (452a) provided on the side thereof which is close to the seating section (43) and having relatively low rigidity, the eaves-section metallic core member (452) also having a high-rigidity section (452b) provided on the side which is away from the seating section (43) and having relatively high rigidity. |
