1. A transmission system including a damper device comprising:
an input element coupled to an engine via a clutch;
an output element coupled to an input shaft of a transmission; and
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 when a total moment of inertia of all rotating 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)≤0.55 is satisfied.
