Abstract

See full text

A damper device includes: an input element coupled to an engine via a clutch; an intermediate element; an output element coupled to an input shaft of a transmission; a first elastic body that is disposed between the input element and the intermediate element; and a second elastic body that is disposed between the intermediate element and the output element and that acts in series with the first elastic body. When a total moment of inertia of the output element and a rotation element that rotates integrally with the output element on the engine side with respect to the input shaft is J2, and a total moment of inertia of all rotation members included between the input shaft and a differential gear coupled to an output shaft of the transmission is JTM, 0.12≤J2/(J2+JTM)≤0.5 is satisfied.
