Abstract:

To provide a miniaturizable damper device and a fluid transmission device.

The damper device includes a planetary gear mechanism 41 having rotating elements including a sun gear 43 as an external gear, a ring gear 44 as an internal gear arranged coaxially with the sun gear 43, and a carrier 45 for holding a pinion gear 46 engaging with the sun gear 43 and the ring gear 44 in a rotatable and revolvable manner, and an elastic body 42 for connecting two of the rotating elements of the planetary gear mechanism 41 to each other in a relatively rotatable manner. In the planetary gear mechanism 41, the driving force of a driving source is input to the ring gear 44, and the driving force input to the ring gear 44 can be transmitted to an output shaft 50. Thus, the device is miniaturizable.
