To reduce effect of resonance of a plurality of intermediate elements while reducing rigidity, in a damper device containing the plurality of intermediate elements.
The damper device 10 includes a drive member 11, a first intermediate member 12 to which a power is transmitted from the drive member 11 by way of a first spring SP1, a second intermediate member 14 to which the power is transmitted from the first intermediate member 12 by way of a second spring SP2, and a driven member 15 to which the power is transmitted from the second intermediate member 14 by way of a third spring SP3. The first intermediate member 12 includes an annular outer periphery 12a which surrounds the first and second springs SP1 and SP2 which are arranged on the outer peripheral side than the third spring SP3, on the same circumference, to adjoin each other; and a pair of spring abutment parts 12b and 12c which are so formed as to protrude to the inner peripheral side from the peripheral edges on both sides of the outer periphery 12a, to face each other, for abutting with the first and second springs SP1 and SP2 at a point between them.
