Abstract
A fluid transmission apparatus including a pump impeller that is connected to an input member coupled to a motor; a turbine runner that is rotatable together with the pump impeller; a damper mechanism that includes an input element, an intermediate element engaged with the input element via a first elastic body and an output element engaged with the intermediate element via a second elastic body; a lock-up clutch mechanism; a dynamic damper that includes a mass body and a third elastic body engaged with the mass body; and a centrifugal pendulum vibration absorber that includes a support member and a plurality of mass bodies each oscillatable with respect to the support member. The third elastic body of the dynamic damper is engaged with one of the intermediate element and the output element. The centrifugal pendulum vibration absorber's support member is connected to the intermediate element or the output element.
