Claim 4:
5. A designing method of a damper device, the method comprising:
providing an input element coupled to an engine via a clutch;
providing an output element coupled to an input shaft of a transmission; and
providing a plurality of elastic bodies disposed between the input element and the output element, wherein
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, setting the moment of inertia J2 so that 0.12≤J2/(J2+JTM)≤0.55 is satisfied.
