Abstract
A damper device including an input element to which power from a motor is transmitted; a first elastic body to which power is transmitted from the input element; a first intermediate element to which power is transmitted from the first elastic body; a second elastic body to which power is transmitted from the first intermediate element; a second intermediate element to which power is transmitted from the second elastic body; a third elastic body to which power is transmitted from the second intermediate element; and an output element to which power is transmitted from the third elastic body. A stiffness of the first elastic body is higher than a stiffness of the second elastic body.
