Abstract
In a damper apparatus, power is transferred, in order, from a motor, to an input, to a first elastic body, to a first element, to a second elastic body, to a second element, to a third elastic body, and to an output. The first and second elastic bodies are disposed radially outward of the third elastic body, and adjacent to each other on a single circumference. The first element has an annular outer peripheral portion that surrounds the first and second elastic bodies, and a pair of contact portions that are formed on peripheral edges on respective sides of the outer peripheral portion to protrude from the peripheral edges radially inward and to face each other, and that are between and in contact with the first elastic body and the second elastic body.
