Patent ID: 8801524

Claim:
A damper apparatus comprising: an input element to which power is transferred from a motor; a first elastic body to which power is transferred from the input element; a first intermediate element to which power is transferred from the first elastic body; a second elastic body to which power is transferred from the first intermediate element; a second intermediate element to which power is transferred from the second elastic body; a third elastic body to which power is transferred from the second intermediate element; and an output element to which power is transferred from the third elastic body, wherein the first and second elastic bodies are coil springs and are disposed radially outward of the third elastic body, and are disposed adjacent to each other on a single circumference, stiffness of the first elastic body being higher than stiffness of the second elastic body; the first intermediate element has (i) an annular outer peripheral portion that surrounds the first and second elastic bodies, the annular outer peripheral portion having two peripheral edge portions, the two peripheral edge portions being apart from each other in an axial direction of the annular outer peripheral portion, and (ii) a pair of contact portions, each of the pair of contact portions being formed on each of the peripheral edge portions of the annular outer peripheral portion and extending from each of the peripheral edge portions radially inward and so as to face each other, and the pair of contact portions being disposed between and in contact with the first elastic body and the second elastic body.
